Learning thermal transfer technology

Thermal transfer is a technique of printing a pattern on a heat-resistant adhesive sheet and printing the pattern of the ink layer onto the finished material by heating and pressurizing. Even for patterns of many colors, since the transfer job is just a process, customers can shorten the operation of printing patterns and reduce the loss of materials (finished products) due to printing errors. With the use of thermal transfer film printing, multicolor patterns can be patterned at a time without trapping, and simple devices can also print realistic patterns.

Thermal transfer equipment is used to decorate aluminum-shaped materials and all kinds of metal plate materials, which can achieve the effect of wood products or marble. Thermal transfer equipment is based on the principle of thermal sublimation. It can quickly transfer the desired wood grain or marble pattern to the surface of aluminum-type powder coating and penetrate the inside of the coating in 3-5 minutes. Micron. Aluminium transfer production process: First, the film is used to heat transfer film before cutting the required size. The second is to use the transfer ultrasonic packaging machine that will cut the good transfer film according to the size of the workpiece to ultrasonically weld the workpiece into the bag. The third is to insert the workpiece wrapping bag made of the transfer film on the packaging platform. The fourth is to place the transfer film on the heat transfer machine platform, and then put 18 aluminum materials. Connect the two ends of the aluminum material to the vacuum tap and lock it. Open the vacuum switch. The transfer film is tight at this time. Close to aluminum. The trolley automatically sends the aluminum material to the baking oven. The baking oven automatically raises the temperature by 220 degrees and keeps it warm for 3 minutes. The cart automatically exits the baking oven. The fifth is to loosen the vacuum tap and remove the workpiece. Sixth, remove the transfer film and check the quality of the workpiece.

Lithography thermal transfer production process, one is to use a film cutting machine to heat transfer paper roll cut into the required size. The second is to attach the thermal transfer paper film to the surface of the workpiece and put it on a flatbed hot stamping machine. The third is to push the flat plate to the heating zone of the platen heat transfer machine, press the pressure plate switch, the platen presses the thermal transfer paper tightly on the workpiece, and heats and insulates for one minute. The fourth is to raise the pressure plate, push the workpiece to the section, remove the transfer film and remove the workpiece and check it.

Thermal transfer technology is widely used in electrical appliances, daily necessities, building materials and other decorative materials. Due to its anti-corrosion, impact resistance, aging resistance, wear resistance, fire resistance, and its ability to remain in outdoor use for 15 years without discoloration, almost all products are produced using this method. For example, when you open the phone case, you can see a dense bar code label inside. Many label requirements can withstand the test of time, long-term non-deformation, no fading, can not be worn out due to contact with solvents, not because of high temperature deformation, discoloration, etc., it is necessary to use a special material print media and printing materials to ensure these characteristics, generally Inkjet and laser printing technologies cannot be achieved.
