Heat transfer film manufacture process
The thermal sublimation process in the clothing industry is the most common process for clothing printing. First, the thermal transfer film is printed by silk screen, and then the pattern on the thermal transfer film is transferred to the garment with a heat transfer machine. This process is particularly suitable for cotton Quality fabric. The production of thermal transfer film by silk screen printing is a complicated process. The video shows one of them. It requires printing water-based glue on the paper, curing the glue on the surface, sprinkling hot melt adhesive powder, and doing it again After drying, the graphic area will be covered with white hot melt adhesive powder. The machines involved in the video are flat screen printers, IR ovens, dusters and infrared tunnel ovens. The first section of the tunnel furnace is used for the drying of glue, and the second section of the tunnel furnace is used for the drying of hot melt powder.
Cylinder hot stamping machine for bucket
The curved hot stamping machine can stamp cylindrical products. When the diameter of the cylinder exceeds 250 mm, the manufacturing difficulty of the hot stamping machine will be greatly increased.
It is very important to keep the pressure balanced during the contact between the plastic bucket and the hot plate. The latest curved hot stamping machine uses the following main technologies:
1) Pneumatic pressurization of hot stamping plate to ensure stable pressure;
2) The hydraulic cylinder is used to push the fixture to ensure the continuous and stable rotation of the plastic bucket.
Hot foil stamping machine for shopping bags
The bronzing machine is a very important equipment in the post-press processing of the packaging printing industry. When the shopping bag needs to be bronzing, the special design of the bronzing machine with the cantilever structure will make the bronzing perfect. The cantilever structure of the bronzing machine can conveniently put the shopping bag on the cantilever workbench. At the same time, the bronzing machine adopts a hydraulic system, which can realize concave and convex embossing and three-dimensional bronzing for the shopping bags of high-grade brand goods.
How to decorate on shopping bag?
When you are shopping in a shopping mall, merchants often put the goods in their shopping bags and sell them together. The shopping bag is a free gift, in addition to the goods, so that you can carry it, the merchant will always use it to promote their brand. It is very common to print text or LOGO on top of shopping bags.
Brands that sell a lot of money may need offset printing, but a large number of small and medium-sized brands may prefer silkscreen and hot stamping. Silk screen printing and hot stamping are very suitable for decoration on the formed shopping bag. Although it is slow, it is adaptable and easy to change, so it is widely welcomed.
Hudraulic hot foil stamping machine for crates
Packaging industry, Die cutting, Embossing, high precision stamping, Decorative painting wood products branded paste painting process requires a lot of pressure. Usually the pressure of the pneumatic hot stamping machine is difficult to more than 15 tons, more than 15 tons stamping pressure hydraulic drive could be considered.
Pneumatic bronzing machine to pass the gas pressure as a medium, there are a lot of uncertainty, because there is more room for the gas molecules, can easily be compressed, so the pressure delivered to the product surface, there would be a process of change. The distance between the liquid molecules is much smaller than gas molecules, once the pressure delivered to the product surface, the pressure will remain for a long time stability.
Hydraulic drive, the machine itself to be equipped with a complete hydraulic system, compared to the pneumatic hot stamping machine, the structure is more complex, some of which will be expensive.
Automatic heat transfer machine for Long rod
For up to 800mm carbon fiber shaft, the heat transfer more difficult, but we have overcome many difficulties, and finally completed a set of automatic transfer machine.
1) carbon fiber material: Carbon fiber is made from organic fibers by carbonization and graphitization treatment obtained microcrystalline graphite materials. Similar to the microstructure of carbon fiber artificial graphite is turbostratic graphite structure. A mechanical performance of new materials, steel accounted for less than 1 / 4, the tensile strength of carbon fiber resin composite materials are generally in 3500Mpa above, is 7-9 times that of steel, tensile elastic modulus of 230 ~ 430Gpa also high in steel. Therefore, the specific strength of CFRP material intensity and the ratio of the density can be achieved 2000Mpa / (g/cm3) above, the specific strength of A3 steel only 59Mpa / (g/cm3) about a specific modulus than steel. Higher than the strength of the material, the smaller the component weight, higher than the modulus, the greater is the stiffness, in this sense indicates that the carbon fiber has broad application prospects in engineering. Carbon fiber is a carbon content higher than 90% of the inorganic polymer fibers. In which the carbon content higher than 99% of said graphite fibers. Carbon fiber axial strength and high modulus, non-creep, fatigue resistance, good heat and electrical conductivity between the metallic and metal between the thermal expansion coefficient, good corrosion resistance, low density of fibers, X-ray transparent too good. But its poor impact resistance, easy to damage, under the action of the acid oxidation, and metal composite occurs when the metal carbide, cementite and electrochemical corrosion. Therefore, before use of carbon fiber surface treatment. Carbon fiber shaft with the use of its excellent fatigue resistance. Through the experiment, as long as the transfer film adhesive layer to make the necessary improvements, the transfer of carbon fiber can achieve good results.
2) transportation; trough the use of the usual storage device can be placed about 150 shaft. As the inherent speed of thermal transfer, automatic transfer machine speed can reach 1200 per hour, higher speed depends on the overall structure of the machine, but given the long shaft, high speed could mean the loss of stability .
3) fixtures; double-stick-type structure, which is slender cylinder for the structure of commonly used products.

Under normal circumstances, a bronzing machine will only install a set of hot stamping foil feeding device and winding device, only hot stamping one color bronzing film, if you want to hot stamp another color bronzing film, you must use another set hot stamping machine, some users may find the cost too high. To this end, we have developed a two-color hot stamping machine (H2-TC4060LPT), which adds a feeding and winding device to the original hot stamping machine, which can stamp two colors of bronzing film at one time. However, this bronzing machine can only be used if the two hot stamping patterns are far apart and parallel to each other.
