1. What is Hot foil stamping machine? The hot stamping machine is a special packaging and printing equipment that uses heat and pressure to transfer the metal coating on the foil film to the product. It is widely used in paper, plastic, leather, glass, wood and other products 2 . Types of hot foil stamping machines. According to the power source of the hot stamping machine to generate pressure, it can be divided into manual hot stamping machine, pneumatic hot stamping machine, hydraulic hot stamping machine and electric hot stamping machine. According to the degree of automation of the hot stamping machine, it can be divided into: semi-automatic hot stamping machine and automatic hot stamping machine 3. Foil stamping and heat transfer printing Hot stamping and thermal transfer are closely related and difficult to distinguish on many occasions. Generally speaking, machines that use anodized aluminum can be called hot stamping machines, machines that use printed transfer films are called heat transfer machines, and machines that use heat transfer films are usually Photoelectric switches will also be installed to identify the pitch points of the thermal transfer printing film to achieve the positioning function! Some people also use whether the ironing head is a flat plate or a rubber roller to distinguish between a hot stamping machine and a heat transfer machine. Obviously, it is also difficult to distinguish them in terms of the applicability of anodized aluminum and heat transfer films! 4. Hot stamping machine operating system The ordinary hot stamping machine adopts the microcomputer control system , the high-end hot stamping machine and automatic hot stamping machine uses the PLC to carry on the control, specially the servo control system hot stamping machine or the automatic hot foil stamping machine, uses the PLC control system quite commonly. 5. Hot stamping machine movement characteristics The actions of the hot stamping machine mainly include the entry and exit and rotation of the worktable, the rotation of products and fixtures, the up and down and rotation actions of the ironing head, and the conveying and unloading actions of the products of the automatic hot stamping machine. Most of these actions are controlled by pneumatics, and a few are controlled by hydraulics. Those that require precise control are driven by motors or servo motors. As the market continues to improve the quality of hot stamping, various automatic hot stamping machines controlled by precision instruments have emerged! 6. How to evaluate the quality of the hot stamping machine? Hot foil stamping machine technology content is low, more and more enterprises began to produce and sell hot stamping machines, hot stamping machines of uneven quality, how to evaluate the quality of hot stamping machine is essential. As the majority of brand-name hot stamping machine is not sold through the network, so, through Alibaba sales of hot stamping machines are low-end hot stamping machine. 1) Design of the factory means: a special design department of the enterprise quality is more reliable. China has 70% of the hot stamping machine manufacturing enterprises and no special design department, the development of new products on-site assembly by the basic, which is extremely adverse to the standardization of production machinery; 2) Processing means: CNC processing costs are higher, but the parts manufactured high precision; visit the factory must inspect whether the factory has CNC machining capacity; 3) Materials Selection: Material selection is very important. Now fierce competition, the vast majority of domestic factories in the selection of the above efforts, only the brand enterprises are willing to insist on the selection criteria above; 7. How to choose hot stamping die? There are two main types of hot stamping plates, one is made by engraving copper plates, and the other is made by pressing silicone rubber. Copper plates are often used for printing substrates with softer materials, such as paper, leather, wood, and cloth; silicone plates are often used for printing substrates with relatively hard materials, such as glass, ceramics, plastics, and metals. For cold stamping processes, silicone rubber plates are also commonly used.

1. What is a screen printer? Screen printing machine uses rubber squeegee to apply pressure on the ink on the screen plate. the pattern is transferred onto the product through the hollow area. It is the most widely used special printing equipment in the industrial field. It is also the most compatible printing equipment for products materials. The UV screen printing process is also a relatively common silk printing process. When using UV inks instead of ordinary dry inks, you need to choose a UV curing machine or LEDUV curing machine to achieve this process. 2 . The difference between the Vacuum table screen printer and T -shaped screen printer The products involved in the plane screen printer are generally divided into two types. One is relatively thin and thinner products, such as paper, film, and general workbenches that need to be inhaled. They will be adsorbed when printing , for a product with a certain shape and quality. You can choose a T -shaped screen printer, which usually makes a fixture to fix. Automatic silk printing opportunities connect to automatic feed mechanisms and unloading mechanisms to achieve the automation of screen printing. 3. Shuttle screen printer and Turntable screen printer The limitations of the single workplace screen printer are very obvious, it is necessary to wait for one product to complete the screen printing before the other product can be placed. The production efficiency is affected. Like the pad printer, the screen printer can also install the shuttle workbench and the turntable workbench. There are two structures, front and rear movements and left and right movement, which are generally large -sized; turntable screen printers are relatively popular screen printers. During the silk seal period, stations continued to rotate, saving working time, and improved production efficiency. The turntable screen printer is generally suitable for products with smaller size. 4. Screen printing machine operating system The ordinary screen printing machine adopts the microcomputer control system to carry on the control, the high-end screen printing machine uses the PLC to carry on the control, specially the servo control system screen printing machine or the automatic screen printing machine, uses the PLC control system quite commonly because it need more parameter setting during screen printing. 5.

Glass is an amorphous solid material, mainly made of silicates (such as quartz sand) that are melted and cooled at high temperatures. It has the characteristics of transparency, resistance to heat and cold, corrosion resistance, and good optical properties. In daily life, glass is widely used in the packaging of wine, cosmetics and other fluids. Silk screen printing technology is the main printing technology for glass bottle decoration. It has the advantages of bright colors, strong coverage, high gloss, anti-friction, acid and alkali resistance, etc. The scraper squeezes the screen printing plate to transfer the ink to the glass bottle through the graphic part of the screen printing plate, forming the same graphic and text as the original. The main steps are as follows: 1. Make a screen printing plate: First, make the designed pattern into a screen printing plate. The pattern part of the printing plate has unobstructed mesh, and the non-pattern part of the mesh is blocked by photosensitive adhesive. 2. Prepare ink: Choose ink suitable for glass material, usually solvent-based glass ink and UV glass ink. 3. Printing: Install the screen printing plate, place the glass bottle on the workbench, operate the machine, the glass bottle rotates, and the ink is transferred to the glass bottle through the graphic part of the printing plate. 4. Drying: Put the printed glass bottle into the dryer for drying. Solvent-based ink requires an IR drying oven, or it can be dried naturally. UV ink requires a UV drying oven. Glass bottles can also be decorated by hot stamping, but the hot stamping of glass bottles is different from the hot stamping of plastics. Generally, hot stamping cannot be done directly. Instead, the surface of the glass bottle must be spray-painted first, and then hot stamped. Another way is to The hot stamping parts are screen-printed with hot stamping varnish, and then hot stamped. In this way, the hot stamping foil will be transferred to the surface of the glass bottle under the action of temperature and pressure. The process is roughly as follows: 1. Design: Silicone templates can be made for spray-painted glass bottles, and screen printing for glass bottles with silk-screen hot stamping varnish must be made first, and then transferred with a rubber roller. 2. Hot stamping: Install the hot stamping foil, choose a suitable semi-automatic hot stamping machine or fully automatic hot stamping machine, and perform hot stamping. Under high-temperature hot pressing, the gold foil is transferred to the surface of the glass bottle. Some automatic production lines integrate silk screen printing and hot stamping to achieve automation. 3. Cooling: Cool the gilded glass bottle so that the gold foil adheres more firmly to the surface of the glass bottle. The effect of hot stamping on glass bottles is very unique and can greatly enhance the texture and grade of the product. However, the cost of this process is relatively high, and it is generally used for the packaging of high-end wine bottles, perfume bottles and other products.

APPPEXPO Shanghai International Printing Exhibition will be held on June 18-21, 2023 at the National Convention and Exhibition Center in Shanghai. The number of exhibitors, exhibition area and number of visitors have all reached a recovery growth of more than 50% after the outbreak. The total exhibition With an area of more than 170,000 square meters, spanning 8 exhibition halls and covering 10 fields, more than 1,400 exhibitors competed to release new products, new technologies, new materials and new designs, attracting a total of 112,068 visitors and buyers.

On May 16, DS printech China 2023, a brand event in the screen printing, textile printing, digital imaging and special printing industries, was grandly opened at the Canton Fair Complex in Pazhou, Guangzhou. This year's exhibition is presented with a high-standard new look, focusing on the theme of "digital integration and green development", including eight major sectors: screen printing, industrial printing, laser engraving, digital printing, intelligent manufacturing, textile printing, clothing embroidery and personalized customization, bringing together nearly 400 well-known domestic and foreign brand companies compete on the same stage, fully displaying new materials, new technologies, and new products in the industry, so that practitioners can fully understand and experience the most advanced digital printing, green low-carbon, energy-saving and high-efficiency cutting-edge scientific and technological achievements and the best printing solutions. At the opening ceremony of the exhibition, Liu Xiaokai, director of the Printing and Publishing Bureau of the Central Propaganda Department and chairman of the China Printing Technology Association, attended and delivered a speech, and the directors of the member countries of the Asia-Pacific Screen Printing Association delivered speeches. Chairman Jiang Wenquan of Guangzhou Teyin Exhibition Service Co., Ltd. delivered a speech on behalf of the organizing committee, saying: "China International Screen Printing and Digital Printing Exhibition was born and developed in the wave of reform and opening up. After 35 years, we have always adhered to the The original intention is to promote and disseminate advanced screen printing, digital printing and special printing technologies as the mission, to help famous brands go global, to promote the sustainable development of the industry as the vision, to keep pace with the times, and to develop and innovate." Then the leaders , The VIP toured the venue.

The screen printing machine uses a screen printing plate, which is a printing plate that separates the graphic area and the non-graphic area on the transparent screen with photosensitive adhesive. The ink can pass through under the pressure of the scraper without being sealed by the photosensitive adhesive. area, while the area enclosed by the photosensitive adhesive cannot see through the ink. Since the ink is in direct contact with the product, the ink layer is the thickest of all printing processes. It is precisely because of this feature that it has an advantage in many packaging and printing fields. 1) Local UV When protecting printed matter, it can be fully protected with varnish, or only partially protected for the graphic area, which can save UV varnish, and can also highlight the three-dimensional effect of the graphic area. Partial UV is only limited to making graphics The screen in the text area, like ordinary screen printing machines, prints UV varnish on the graphic area and then performs UV curing. A flat screen printing machine plus a flat UV curing machine or UVLED curing machine is enough. 2) dusting Paper packaging has a kind of powder decoration, which is to attach metal powder to the part of the paper packaging to form a visual impact. Metal powder is usually made of very fine metal particles and has the characteristics of metal flash. The powder spreading process is also closely combined with the silk screen printing process. Generally, the glue is printed on the area that needs to be powdered, and then the powder is sprayed and cured with a powder spreader. The metal powder will be firmly fixed on the surface of the glue. The powder spreading process is generally divided into two processes: IR curing and UV curing. IR curing belongs to heat curing, and heat curing glue should be used, which has high fastness. UV glue is used for UV curing, and the fastness is slightly worse. The specific equipment selected is a flat screen printing machine plus a powder spreading machine plus an IR tunnel furnace or a flat screen printing machine plus a UV curing machine and a powder spreading machine.

Glass bottle is the safest packaging container. It has an advantage in the packaging of food, cosmetics, wine and other products. Usually, glass bottles need to be printed square glass bottle A square glass bottle is a bottle that is square in shape. It consists of four planes and requires printing on four sides. The printing of square bottles comes down to plane printing. You can use a plane screen printing machine to print one side at a time, or install an automatic rotating fixture on the plane screen printing machine to complete two or four sides of printing at a time. Square bottles can also be printed on the automatic screen printing machine, one is to use the four-color automatic flat screen printing machine for silk screen printing, the other is to use the four-color automatic curved screen printing machine to print on the automatic screen printing machine, common Using UV glass ink. The hot stamping of the square bottle is similar to the hot stamping of the flat glass. First, the glass varnish is screen-printed, and then the hot stamping machine is used for hot stamping. The current glass thermal transfer film is also relatively mature and can be directly used for thermal transfer printing to complete multi-color decoration at one time. round glass bottle Round glass bottles are one of the most stocked packaging forms on the market, and they still need silk screen printing, bronzing, heat transfer printing and other decoration methods. Round glass bottles, like plastic bottles, are most commonly used for silk screen printing. Whether it is a semi-automatic screen printing machine or a fully automatic screen printing machine, it is the machine that users like to choose. Fully automatic screen printing machines often use UV screen printing technology, while semi-automatic screen printing machines use ink UV type and heat curing type are more common. The heat transfer printing process for round bottles uses a curved surface heat transfer machine and a glass heat transfer film Round glass bottles also often encounter hot stamping process, similar to flat products, it needs curved screen printing machine to print glass varnish and then use heat transfer machine for hot stamping. On the fully automatic printing machine, the silk screen printing machine and heat transfer machine are combined on one machine to complete silk screen printing and bronzing at one time. A UV curing or heat curing device will be installed between silk screen printing and bronzing to accelerate the drying of the ink.

The fully automatic garment printing machine has a unique structure in the screen printing machine. All the printing heads and worktables rotate around a central layout. Due to the compact structure, it can achieve up to 10-12 colors in a leisurely space. It is suitable for Medium and high-precision piece printing, stable operation, high efficiency, convenient adjustment, exquisite structure and so on. The high-precision column rotation mechanism is adopted to ensure the symmetry of the machine rotation; The high-strength cast aluminum workbench is adopted, and the workbench is fixed by a pull shaft to ensure no shaking during operation; PLC program control, easy to operate, all failures are equipped with alarm devices, which is convenient for machine maintenance; The screen mechanism can be adjusted in three dimensions, which is suitable for high-precision silk screen printing; Adopt IR drying device, high efficiency, suitable for fast drying of inter-color screen printing Cloth screen printing mainly uses thermosetting inks and various water-based or oil-based glues, which need to be heated to dry. The multi-color automatic printing machine adopts multiple sets of infrared drying devices; each set of drying devices is equipped with three sets of IR lamps, and one set, or two sets, or three sets can be turned on as needed. The drying device can be manually lifted to facilitate inspection, removal and installation of the lamp tube. Both the screen device and the scraper device have a three-dimensional position adjustment function, which is very suitable for precise multi-color registration screen printing. The screen frame device can be lifted to facilitate the observation, cleaning and color adjustment of the screen. The whole machine adopts advanced PLC control technology, which integrates all the actions of the operation into the control system, making the operation more convenient. All machine faults adopt alarm device and sensor technology to report the machine's implementation and operation status to the operator in time, so as to facilitate timely troubleshooting of faults. The program adopts a humanized dialogue mode, and the user can rationalize the operation process according to different printing processes. The working table is made of high-strength cast aluminum material, which has good stability and is not easy to deform; The workbench is installed by a formed aluminum alloy cantilever and supported by a tie rod, which has good stability and will not shake during operation. The rotation of the worktable is controlled by a precision indexing plate, which has good positioning and is conducive to accurate overprinting. The whole machine is centered on a high-strength column. The column is welded with angle steel, and the drying device is located above the radius of gyration of the column, so the operation is more stable. In order to prevent the shaking of the screen frame device, there are steel materials between the column and the screen frame device for tensioning, which greatly improves the screen quality. Stability of the running process. The machine auxiliary device is mainly made of aluminum alloy material, with exquisite design and beautiful vision.

Plastic turnover boxes and plastic frames occupy an important position in the transshipment of fragile products and fragmented products, especially in various factories, they are almost indispensable. Plastic turnover boxes are injection-molded with polyolefin materials on large injection molding machines. According to their surface characteristics, we simply classify them into turnover boxes with a flat surface and turnover boxes with a rib structure on the surface. How to print the turnover box is a concern of many people. 1) Bronzing At the entrance of shops, pharmacies, and restaurants, you sometimes find piled up turnover boxes, and there are often golden words on a certain position on it, and these are bronzing. Hot stamping is no different for turnover boxes with a flat surface and a turnover box with a rib structure on the surface. As long as the hot stamping position is adjusted, the hot stamping is no problem. But for the turnover box with rib structure, you may need to make a thicker hot stamping plate to avoid the influence of ribs. 2) Thermal transfer printing Turnover boxes seldom use heat transfer printing, but some shopping baskets and fruit baskets used in supermarkets are decorated with bright and eye-catching images in order to attract customers, so you must use heat transfer machines. However, thermal transfer printing is not suitable for turnover boxes with ribbed structures on the surface. Compared with bronzing, thermal transfer printing has richer colors and stronger expressive force. 3) silk screen It is also very common to use silk screen printing for turnover boxes, which has many similarities with bronzing. Since the size of the screen cannot be made too small, there will be some requirements for the turnover box with a rib structure, for example, the area of the part to be printed should not be too small, and the screen must be able to fall. Obviously, if the surface is a completely smooth turnover box, there is no limit to silk screen printing. Of course, if you print many colors, you can buy multiple screen printing machines to print one color and one color. Generally speaking, the adhesion can be solved by choosing the appropriate polyolefin ink, or you can choose a special flame treatment machine to deal with it. 4) pad printing It is not very common to use pad printing on turnover boxes, but when those turnover boxes with rib structure need to be printed, and the printing position is not large, you can consider using pad printing. The outstanding advantage of pad printing is the deformation of the pad printing rubber head, so it has good adaptability to any shape of the product. When manufacturing such a pad printing machine, the travel of the pad printing machine needs to be considered, because the part to be printed on the turnover box may be close to the center. How about it, do you have a preliminary understanding of the printing of plastic turnover boxes and plastic frames?

Limitations efficiency pneumatic screen printing machine by air transport is difficult to have a big raise, with the cam arm structure to control the network version of the drop becomes reduced screen time is an important way to fall. So efficient than the inclined wall screen printing machine screen printing machine pneumatic efficiency of 22%. From a structural considerations, pneumatic screen printing machine is basically vertical lift, the structure is more complex when used to manufacture than the large format screen printing machine, manufacturing costs will be significantly improved, so in large format screen printing machine structure, the oblique wall screen printing machine has obvious advantages. But the oblique arm printing machine also has the obvious disadvantage is its repeatability is not high, due to the presence of structural parts in contact rocker cam wear, it is difficult to improve the manufacturing process, screen printing machine oblique arm overlay network is not suitable for high-precision and high-precision circuit board , switches sophisticated electronic components and printed film, which is more suitable for paper packaging for example, UV screen printing, screen printing and thermal transfer film matte, gloss and other local decorative printing field! The scraper mechanism of the oblique arm type screen printing machine, like the screen mechanism, realizes periodic reciprocating motion through two cams installed on the transmission shaft driven by the transmission motor, so that its speed is significantly increased, which makes it a local in terms of paper packaging. UV varnish, UV frost, UV matte and ceramic decal paper, heat transfer paper has a great advantage in the production. For further process optimization, the oblique arm screen printing machine can be equipped with a robot to realize the connection between automatic feeding and UV curing machine, and the work intensity of the operator is further reduced. With the expansion of fully automated screen printing machines in the global market, an automatic feeding device is added to the front end of the oblique arm type screen printing machine, and an automatic positioning device is added to the workbench. The production line of the fully automated oblique arm type screen printing machine is continuously popularized.

Cups are containers for drinks that people commonly use in their daily lives. There are many kinds and wide range of uses. They can hold beverages, coffee, water and some soups. Whether it is family, social occasions or outdoor sports, Du can see it. 1) Material: The material of the cup covers almost all kinds: paper, plastic, metal, ceramic, glass, wood, rubber. 2) Shape: Most of them are cones with large mouths, there are also some cylinders, and some more complex shapes: 3) Structure, some cups have no lids, some cups have lids, some cups have handles, and some cups have no handles. 4) Some cups will be carried with you, and some cups will be placed at home. Most of the disposable cups, especially those used for leisure drinks, should be thrown away after they are used up to avoid repeated use. The printing of cups involves almost all printing methods, offset printing, flexographic printing, hot stamping, heat transfer, silk screen printing, pad printing. Screen printing is the most widely used, especially for those cups with handles, which cannot be replaced by other printing methods. As far as screen printing is concerned, semi-automatic screen printing and full-automatic screen printing are all good methods. The screen printing of disposable plastic cups or paper cups that are currently popular in the market, due to the huge amount of use, has begun to use automatic screen printing machines more and more widely. Fully automatic screen printing machine specially designed for disposable cups such as milk tea cups, coffee cups, beverage cups, etc. The width of the integrated synchronous feeding and feeding device of the whole machine can be adjusted flexibly, which is convenient to adjust according to the size of the cup; the speed can be adjusted steplessly to match the transportation speed with the printing speed; Automatic manipulator push feeding; Online flame treatment device or plasma treatment can improve the surface tension of PE material and increase the adhesion of ink; Stable vertical turntable transmission system, stable operation and high precision; Automatic screen printing device, the fixture can be changed according to the size of the cup; electronic sensors are installed in the printing area to realize the function of no part without printing; photoelectric switch tracking system can be installed to realize color printing. High-performance UVLED drying device, instant drying of ink; energy saving, safe and environmentally friendly. The whole machine realizes mechanical transmission and touch screen operation, which can easily realize man-machine dialogue and make the operation more handy; The main parts are processed by CNC, the high-quality processing accuracy ensures the stability of high-speed operation, and the printing speed is up to 2000pcs/h; The electrical components and control system of the whole machine use German and Japanese components to ensure stable printing quality.

The glass surface cannot be gilded directly. If gilding is required, a coating can be established on the glass surface first. There are many ways to establish the coating, such as spraying, silk screen printing, and thermal transfer printing. Screen printing is one of the more common processes for establishing coatings. It has the characteristics of uniformity, easy control of thickness, and good adaptability to inks of various components. It is widely used in glass bottles, glass cups, or glass plates and other products. Applications. However, it is difficult to print the surface of irregular products such as spheres, concave surfaces, convex surfaces, etc. with silk screen printing. If such bottles need bronzing, other processes may be considered. We naturally think of the pad printing process. The pad printing machine is equipped with a very soft rubber head for printing, which can wrap the surface of very complex products, showing irreplaceability on the surface of spheres, bowls and even more complex products. The customer's product is a glass bottle with a shape similar to a pineapple. There are two relatively smooth but spherical areas on the surface of the bottle body that need bronzing, so naturally they will consider using pad printing to print the bottom layer first. In this experiment, we found a kind of glass ink that can be bronzing, carried out multiple pad printing, established the coating, and then used a flat bronzing machine to install a silicone mold with a curvature for bronzing, which better met the customer's needs. Due to the multiple printing and drying of ink involved in pad printing, and even the difficult bronzing, the efficiency of the product is low. For this reason, we have also designed an automatic pad printing and bronzing machine that integrates pad printing and bronzing, which greatly improves the production efficiency.

Nowadays, people's household water generally uses bottled water, and the PC mineral water bucket with a capacity of 5 gallons or about 18 liters is the most common, and it is often used in conjunction with a water heater. 5-gallon mineral water buckets have different shapes from different manufacturers, but they are generally cylindrical. In order to increase the strength, most factories will make annular bulges, and some mineral water buckets are specially designed with handles. The size of the mineral water bucket is about 300mm in diameter and about 350mm in height. In order to improve brand recognition, manufacturers and water providers will establish their own identification marks on the barrel, such as lettering on the blow molding mold, or sticking supplier information in the form of self-adhesive labels. Today we mainly discuss the application of silk screen printing process on 5 gallon mineral water bucket In fact, silk screen printing is currently the main process for decoration of 5 gallon mineral water buckets. Screen printing has low cost, simple operation and good printing effect. Whether it is a semi-automatic screen printing machine or a fully automatic screen printing machine, perfect printing can be achieved on the mineral water bucket. For semi-automatic screen printing machines, we may encounter how to choose a suitable machine for customers. The diameter of the mineral water bucket is about 300mm, and the length of its unfolded surface reaches 1000mm. If you want to print on the entire perimeter, you must choose For a curved screen printing machine with a long stroke like the S-380S, the price of the machine will be higher. However, there are also many users who only need to print on half of the perimeter of the surface of the mineral water bucket, and do not need such a large stroke. You only need to recommend the S-125SM curved screen printing machine with a stroke of only 400mm. Such machines are also much cheaper. For those large-scale mineral water bucket manufacturers, the efficiency of the semi-automatic screen printing machine may be too low to meet the customer's fast delivery requirements. You can also choose a fully automatic mineral water bucket screen printing machine, which will greatly improve the printing speed. Of course, The price of such a machine is very expensive. The silk screen printing of mineral water buckets is not complicated, but when you buy a silk screen printing machine, you need to communicate with the supplier in detail. Considering that the surface morphology of mineral water buckets is complex, how to use special screen and scraper structure may require special design. .

Pad printing machines are suitable for printing products with complex appearance or products that cannot be realized by silk screen printing. In most cases, it is suitable for products with relatively small dimensions. However, with the development of printing technology and the exchange and integration of various industries, pad printing machines have also begun to set foot in other In some fields, such as the tableware industry of daily ceramics, some bowls, plates, dishes, spoons and other products. Generally speaking, the shapes of these products are relatively complex, and it is difficult to print by conventional printing methods. Therefore, the early decoration method is to print the graphics and text on the decals first, and then transfer them to the surface of the tableware. The production of decals is a comparison Complicated craftsmanship, and most of the processes of decals need to be done by hand. With the rise in labor costs and the decline in the price of finished products, this traditional craftsmanship is becoming more and more unsuitable for reality. The latest market trend is the use of pad printing machines. The biggest advantage of pad printing machines is that they can use a soft rubber head to wrap the product to the maximum extent, and then transfer the pattern to the surface of the product, and the graphics and text on the steel plate are transferred to the deformation of the product surface. It can be corrected by continuously modifying the pre-deformation of the pad printing plate. Ceramic pad printing machines currently have single-color, double-color, three-color, and four-color. Due to the very large size of the steel plate, at present, an open structure is basically used for ink supply. The control system also has pneumatic drive steering servo motor drive. The most difficult thing in the pad printing of ceramic tableware is not the manufacture of the machine, but the production of steel plates according to the pattern of the product, and the multiple printing tests after customizing the pad printing head. Once the test is completed, the formal production of subsequent products becomes simple.

Europeans like a Frisbee sport very much, and the Frisbee in motion is made of polyethylene material. The factory that makes the Frisbee will require bronzing and heat transfer. In addition to the gloss produced by bronzing and the rich tones produced by thermal transfer, users pay great attention to the environmental protection of the production process. There is no ink in the production process of bronzing and thermal transfer, which conforms to strict environmental protection standards, so it is favored by such sports equipment manufacturers. It is more common to use the hot stamping process for plastic Frisbees, but some users also consult the thermal transfer process. So can the frisbee use the thermal transfer process, and what kind of machine should I choose? The so-called thermal transfer printing is to print the pattern that needs to be transferred onto the PET film by gravure printing, screen printing or inkjet printing, and then use a hot stamping machine and a thermal transfer machine to perform heat and pressure operations. First of all, we have defined the thermal transfer machine as the roller embossing type, and the bronzing machine as the flat embossing type. To perform the thermal transfer process, it is necessary to install an electric eye tracking system on the machine. The electric eye tracking system can control the conveying motor of the thermal transfer film to brake according to a certain position, and then a heat and pressure lamination action occurs. This is consistent with our common thermal transfer process. So can thermal transfer be achieved on a flat bronzing machine? The answer is also yes. The flat bronzing machine can also be installed with thermal transfer film, and similarly, the electric eye tracking system can also be installed. Therefore, as long as a flat silicone plate is installed on the flat foil stamping machine, and the necessary tension control is performed on the conveying device of the foil stamping paper, thermal transfer printing can still be achieved. But usually we do not recommend users to use a flat bronzing machine to realize the thermal transfer process, because the roller embossing type machine is a line contact, and the printing quality is easy to ensure, while the flat bronzing uses a surface contact, and the contact area is easily mixed with air, resulting in The adhesion of the local film paper decreased. However, in some cases, a flat heat transfer process must be used, such as the heat transfer of snowboard wheels, and the heat transfer of the top of some concave caps. The hot stamping on the plastic Frisbee needs a lot of pressure. The pressure of more than 5 tons is possible to achieve the perfect hot stamping effect. On the plastic material, the polyolefin material is not easy to be hot stamped. In addition to choosing special hot stamping paper, it is also necessary to High-pressure bronzing machine, if the bronzing pressure is not enough, it is difficult for the bronzing paper to obtain excellent adhesion. The hot stamping on the plastic Frisbee has also become multi-colored in recent years. Due to the low entry barrier for single-color hot stamping, many users are facing increasing market pressure. They consider three-color or even more color hot stamping on the plastic Frisbee. The principle of multi-color bronzing and multi-color pad printing is the same, but there is an obvious difference. Multi-color bronzing can only be the superposition of color blocks, and it is impossible to reproduce the tone, and different colors of bronzing paper are not allowed to appear. overlay. Multi-color bronzing machines are either in-line or turntable. At present, there are many turntables on the market.

The market differentiation of pad printing machines has become more and more obvious in recent years. Some users are sensitive to price requirements, while others are sensitive to quality. Different manufacturers responded quickly to their market segments, and those that supplied pad printing machines to high-end customers continued to refine their products. So what counts as high-quality pad printing? What are the important components that a high-quality pad printing machine usually includes? A pad printing machine is a simple printing machine that can print on the surface of products with complex shapes. Although most people are only interested in its ability to print, some people are concerned about whether it can achieve more precise printing. For example, what is the repeatability of its multiple printings, and how accurate is the reproduction of details during halftone printing? "Is its ink layer uniform and constant?" In order to realize these functions, the pad printing machine must be the same as other printing machines, requiring high processing precision of each part of the machine, high precision of mechanical assembly, and complete functions of the machine. 1) Automatic glue head cleaning device The depth of the pad printing plate determines its ink storage capacity. During the process of dipping the ink and transferring the pad printing pad, some ink will remain on the surface of the pad, and the accumulation will affect the thickness and clarity of the ink layer to a certain extent. The installation of automatic cleaning glue head device can effectively remove the ink on the surface of the glue head and improve the printing quality. 2) Servo drive+PLC The action of the pad printing machine roughly includes the ink taking of the pad printing head, the movement of the pad printing head, and the printing of the pad printing head. Their moving speed and position have an impact on the printing. Servo drive system and man-machine are used. The program control of the interface can realize the digital control of these actions and avoid misjudgment in experience. The biggest advantage of the human-machine interface is that when printing different products, it can be based on the different properties of the product, such as material, size, and angle. , the printing effect can be set differently. 3) Prepress processing Pad printing will also involve quite a lot of injection molded PP and PE materials, or some other materials that are not easy to print, you have to consider prepress, and the best prepress is plasma, although plasma is a bit expensive. , but in terms of printing quality stability, plasma has obvious advantages. 4) Linear guide The guiding device is an important factor for the mechanical operation to achieve the repeatability. At present, the use of linear guide rails will ensure the repeatability of the pad printing head and the steel plate moving back and forth, which is much more accurate than the traditional guide post. 5) Machining accuracy of mechanical parts The manufacturing threshold of the pad printing machine is low. It can be manufactured by buying a few lathes and milling machines, and the market is also good. In most cases, the products printed by the pad printing machine do not need too high precision. These pad printing machines no problem. But when you are involved in electronic products, thick film circuits, mobile phone lenses or some military products, it may be required to use CNC to process mechanical parts to achieve higher accuracy, only the accuracy of the parts is high enough, and the accuracy of the assembled machine is also will be higher.

Construction sites, heavy machinery factories and some occasions where there are falling objects, motorcycle drivers are required to wear helmets for protection. The decoration of safety helmets is a problem that printing practitioners often encounter. So how is the helmet decorated? Through a simple survey of industry personnel, it can be found that safety helmets can be decorated by pad printing, silk screen printing, bronzing, thermal transfer printing, water transfer printing, labeling, etc. Pad printing is the most mature and common decoration process. The reason is that pad printing is very suitable for products such as safety helmets with irregular shapes and fixed printing positions, and it is also very easy to realize mechanized operation. Monochrome pad printing Some helmets only require a single-color logo to be printed on the forehead of the helmet. This is a relatively simple color. As long as it is a single-color pad printing machine, it can basically meet the conditions. All you have done is how to make the jig that holds the hard hat in place. Multi-color pad printing More hard hats require multiple colors to be printed on the forehead, which is why you need to choose a shuttle-type multi-color pad printer. The reason why we choose a shuttle-type pad printing machine is that, in addition to the high overprinting accuracy, the shuttle-type pad printing machine also accommodates a relatively large size of the product, and the size of the safety helmet is relatively large. The turntable type pad printing machine cannot fit such a helmet. The multi-color same-position pad printing process is not complicated, and the pneumatic shuttle pad printer and servo shuttle pad printer can easily meet the requirements. Multi-color pad printing at different positions A considerable number of safety helmets are not only printed on the forehead, but also printed on the back, sides and even more irregular positions of the hat, so it is difficult for ordinary shuttle pad printing machines to meet the requirements, you must customize one. The multi-color shuttle pad printing machine with a servo rotating device on the worktable, considering that some large companies have high requirements for the printing accuracy and position accuracy of the safety helmet, it becomes necessary to use the full servo motor control for the pad printing machine. The pad printing machine controlled by servo motor can accurately control the front and rear, left and right, up and down, and angle according to the printing position of the safety helmet, so it has been widely used in many high-demand pad printing machines in recent years. In addition to the servo rotating device of the worktable, the control of the printing angle of the rubber head also tends to be servoed. For some electronic products, toy products and kitchen utensils, the printing position is very special. In addition to the multi-angle rotation of the fixture, the multi-angle rotation of the glue head will greatly improve the production efficiency.

There are three types of hot stamping machine: Pneumatic hot stamping machine, hydraulic stamping machine and electric hot stamping machine. 1) From the stamping pressure point of view, the same size stamping machine, hydraulic stamping machine, followed by the electric hot stamping machine, pneumatic hot stamping machine minimum; 2) From the use of perspective, pneumatic stamping machine widely used, focusing on a single product bronzing, electric hot stamping machine is suitable for paper and film, while the hydraulic stamping machine is more suitable for embossing, die-cutting and large gilt; 3) from the speed point of view, electric hot stamping machine fastest, followed by hydraulic stamping machine and pneumatic hot stamping machine; 4) in terms of stability, the compressibility of the fluid is small, so, hydraulic stamping machine, high stability, without the need for additional ordering air compressor Hydraulic hot stamping machine( HH-TC3040LP HH-TC4040LP HH-TC4050LPT HH-TC4060LPT) is a hot stamping machine that uses a hydraulic pump to provide flowing liquid to the action unit of the hot stamping machine to generate pressure. As far as the action of the current flat hot stamping machine is concerned, the up and down hot stamping action can be controlled by hydraulic pressure. Some flat hot stamping machines require a workbench. It can enter and exit automatically, and the movement of this entry and exit can also be controlled by hydraulic pressure. Up and down movements require more pressure, while in and out movements require less pressure. The pressure of the bronzing machine is a very important parameter to obtain the quality of bronzing and realize some bronzing processes. For some products that are difficult to bronzing, the pressure can make up for the defects. For example: For polyolefin materials and wood products, it is difficult to find very suitable bronzing paper. If the pressure is large enough, the adhesion of bronzing can also be guaranteed. There are two situations in which hot stamping on paper often requires greater pressure. One is that the size of the paper is large, and the other is that embossing is required. Hydraulic hot stamping machines are all good choices. Hydraulic hot stamping machines often carry hydraulic pumps, and users can work by adding hydraulic oil themselves. Hydraulic oil has a great relationship with the hydraulic components of the machine. It is necessary to choose high-quality and wear-resistant grades, and it should be checked frequently. If the hydraulic oil is obviously discolored, thickened, and impurities appear, it should be replaced in time.

Pad printing machines have been popularized for decades, and manufacturers are constantly upgrading in terms of structure and performance. Users will also provide advice based on their own operating experience. China is an important participant in the supply chain of the world pad printing machine market, providing global users with annual A wide variety of pad printers with different uses. For users who are new to pad printers, there are now more options for choosing pad printers than before, which means that you must understand the relationship between pad printer performance and price. If choosing a pad printer is important, I hope this article can help you understand this knowledge. 1. Choose an open pad printer or a closed pad printer? The environmental tendencies of printing presses have been talked about for many years, and this is the number one issue for operators to provide health assurance. The quality control obtained by the use of solvent-based inks in pad printing machines has been difficult to replace by other water-based inks or UV inks for many years. For a long time, solvent-based inks will remain for a long time, and pad printing machines can do structural work. The first attempt is to adopt a closed oil cup structure, which has gradually entered the mainstream market in recent years, especially in developed countries in Europe and the United States. 2. Choose a touch screen or a microcomputer? The structure of the original pad printing machine is relatively simple, and the action form is not complicated. It is relatively simple to use a microcomputer program to control, but the microcomputer program is a fixed program that is encapsulated, and the user cannot expand the function. When the structure of the pad printing machine is When it becomes complex and more functions are required, a PLC operating system with man-machine dialogue function may be more suitable. Manufacturers of pad printing machines have faced changes in the market in recent years. A more obvious trend is to manufacture pad printing machines with a high degree of automation, so the use of programmable and visual programs for mechanical control may be essential. For users, the pad printing machine with human-machine interface is better at realizing different printing tasks according to your own habits. 3. What kind of plates are used? Pad printing machines generally use thick steel plates, thin steel plates and resin plates. For domestic users, the use of resin plates is not a good option. Therefore, steel plates are generally used. The plate-making method of steel plates involves a process that is not very environmentally friendly, but as far as the current environmental protection policy is concerned, it is acceptable. Many European customers prefer to use resin plates, which are made with only water and alcohol, and are preferred despite their low print durability. 4 Cleaning the plastic head unit The cleaning head unit is a separate part, you may need it for an additional fee, and you may opt out of it. We know that cleaning the glue head is done manually at first, and it is important to keep a part of the residue on the surface of the glue head in the process of transferring ink. Accumulation for a period of time will cause quality problems. The usual method is to remove it with adhesive tape. Causes downtime, but the pad printer installed with the automatic cleaning glue head device will perform the online cleaning step, and the time required to clean the glue head is far less than the time to manually clean the glue head after the shutdown. On higher-end pad printers and automated pad printers, it has become very common to install an automatic cleaning head device. 5. Robot There are so many types of products printed by pad printing machines and screen printing machines that it is difficult for you to use a standard mechanical structure to achieve all printing tasks. You can only design different transfer devices according to different products. In this regard, the role of the manipulator is very powerful. The manipulator can grasp different products and feed materials to serve the main body of the printing press. The manipulator imitates the action of the hand, which does not seem to be continuous, but it is very easy to carry large spaces and long distances. It is widely used in rotary pad printing machines or products with complex product shapes. Of course, not all products are suitable for using robots. You must discuss with your partners what structure to use to maximize efficiency. 6. Workbench There are many types of workbenches for pad printing machines, such as shuttle workbenches, turntable workbenches, and disc workbenches. Each workbench now has a variety of structures to choose from. For example, shuttle-type worktables are controlled by pneumatics and servo motors. Many users have instructed that the positioning accuracy of servo-motor-controlled worktables is relatively high. In order to improve the accuracy of rotary table-type worktables, linear guide rails have also been used in recent years. , the trend of servo motor drive. You will also find many users in the market using disc-type workbenches. The disc-type workbench is an intermediate form of the transition from semi-automatic pad printing machines to fully-automatic pad printing machines. With the cooperation, the market share is steadily increasing.
