What is thermal transfer technology?

Detailed explanation of the principle of thermal transfer technology?

Thermal transfer printing technology has been used in fabric thermal transfer printing production for a long time. With the rapid development of high technology, thermal transfer printing technology has become more and more widely used.

Ink types are classified into heat press transfer type and sublimation transfer type.

The objects to be transferred include fabrics, plastics (boards, sheets, films), ceramics and metal coated plates, etc.; the printing methods can be divided into screen printing, flat printing, gravure printing, embossed printing, inkjet and ribbon

Printing, etc.; from the classification of substrates, there are thermal transfer paper and thermal transfer plastic film, etc.

Mainly used for plastic, EVA, stainless steel, suitable for mass production.

Selection of heat press machine: 1. The core component of the heat press machine is the heating plate, so you should pay special attention when choosing a heat press machine.

2. The upper and lower plates should be made of aluminum, and the heating pipes should be cast inside the aluminum plates.

If the upper plate is an aluminum plate with grooves and then a heating tube is attached to it, it will cause unnecessary energy loss. It will also have shortcomings such as slow temperature rise and large constant temperature difference during use.

3. If the lower plate is made of iron plate or other materials, it will be easily deformed and aged if it works in a high temperature and high pressure environment for a long time.

4. Depending on the area of ??the heating plate, there are weight standards for the upper and lower plates. If it is too light or too thin, the heating plate will be easily deformed and affect its use.

Generally speaking, the heavier the weight, the more reliable the performance.

After the upper plate of the heat press machine is pressed down, it should be absolutely parallel to the lower plate.

To test whether the upper and lower plates bite tightly, you can place a piece of cardboard or other sheet-like tough material objects at the four corners respectively, and then press the handle. After the upper and lower plates bite and become stuck, turn the cardboard toward

By pulling it outward, you can know whether the upper and lower plates are flat and whether the machine is qualified.
