Thermal transfer printing is a technique of printing patterns or patterns on heat-resistant adhesive tape, and printing the patterns of the ink layer on the finished material by heating and pressing. Even if it is a multi-color pattern, since the transfer operation is only a process, the customer can shorten the printing pattern operation and reduce the loss of material (finished product) due to printing errors. Using thermal transfer film printing, multi-color patterns can be formed into a map at one time, without color registration, and simple equipment can also print realistic patterns, and this process can be applied to the top cover of the disc.

Thermal transfer equipment is used to decorate aluminum profiles and various metal plates, and can achieve the effect of wood products or marble. The thermal transfer equipment works according to the principle of thermal sublimation, which can quickly transfer the desired wood grain or marble grain to the surface of the powder coating of the aluminum profile within 3-5 minutes and penetrate into the interior of the coating 40-60 microns.

Aluminum transfer production process: First, use a film machine to roll the thermal transfer film to the required size. The second is to use a transfer ultrasonic packaging machine to weld the cut transfer film into a workpiece wrapping bag by ultrasonic welding according to the size of the workpiece. The third is to insert the workpiece into the workpiece wrapping bag made of transfer film on the packaging platform. The fourth is to place the workpiece wrapped with the transfer film on the trolley platform of the heat transfer machine, and 18 aluminum materials can be placed in turn. Connect the two ends of the aluminum material to the vacuum tap and lock it, and turn on the vacuum switch. At this time, the transfer film is tightly Fits snugly on aluminum. The trolley automatically sends the aluminum material to the baking oven, the baking oven automatically heats up to 220 degrees and keeps the temperature for 3 minutes, and the trolley automatically exits the baking oven. Fifth, loosen the vacuum tap and remove the workpiece. Sixth, remove the transfer film and check the quality of the workpiece.

In the production process of lithographic heat transfer, the first is to use a film cutting machine to cut the heat transfer paper roll into the required size. The second is to attach the thermal transfer paper film to the surface of the workpiece and place it on the flatbed thermal printer. The third is to push the plate to the heating area of ​​the plate heat transfer machine, press the switch of the platen, and the platen presses the heat transfer paper tightly on the workpiece, heats it and keeps it warm for one minute. The fourth is to lift the pressure plate, push the workpiece to the section, remove the transfer film, remove the workpiece and inspect it.

Thermal transfer technology is widely used in electrical appliances, daily necessities, building materials decoration, etc. Due to the properties of corrosion resistance, impact resistance, aging resistance, wear resistance, fire resistance, and 15 years of outdoor use without discoloration, almost all products use labels made in this way. For example, when you open the phone case, you can see the dense labels with barcodes inside. Many labels are required to be able to withstand the test of time, not deformed for a long time, not fading, not worn due to contact with solvents, not deformed and discolored due to high temperature, etc. Therefore, it is necessary to use a special material for printing media and printing materials to ensure these characteristics, generally Inkjet, laser printing technology is unreachable.
