Transfer printing refers to the printing method of transferring the image and text on the central carrier film to the substrate with corresponding pressure. According to the different selection pressure, transfer can be divided into: heat transfer, water transfer, air transfer, screen transfer, low temperature transfer, etc.
1、 Heat transfer printing skills
Heat transfer printing is a kind of skill to print the zebra picture of ink layer on the product data by heating and pressurizing. Even for multi-color pictures, since the transfer operation is only one process, customers can shorten the printing operation and reduce the loss of information (products) caused by printing errors. By using heat transfer film printing, multi-color pictures can be drawn at one time, without chromatic registration, and simple equipment can also print vivid pictures.
The heat transfer printing equipment is used to decorate aluminum shaped materials and all kinds of metal plates, which can play the role of wood products or marble. The heat transfer equipment is based on the principle of heat sublimation. It can transfer the required wood grain or marble grain to the surface of aluminum powder coating in 3-5 minutes and can penetrate 40-60 microns inside the coating. Aluminum transfer production process: one is to use the film machine to cut the heat transfer film. The other is to weld the cut transfer film with the transfer ultrasonic packaging machine to the workpiece package bag according to the size of the workpiece. Third, in the packaging channel, we use the transfer film to wrap the workpiece bag. The fourth is to place the work piece wrapped with transfer film on the channel of the car of the heat transfer machine. 18 pieces of aluminum can be placed in sequence. Connect the two ends of the aluminum to the vacuum tap and lock it. Open the vacuum switch. At this moment, the transfer film is tightly attached to the aluminum. The car takes the initiative to send the aluminum materials to the baking furnace, the baking furnace takes the initiative to raise the temperature by 220 degrees and keep the temperature for 3 minutes, and the car takes the initiative to exit the baking furnace. 5. Loosen the vacuum tap and take down the workpiece.
