The hot stamping film needs a certain high temperature when it is used or processed, so that the pattern or color can be printed on the product, but if the temperature is too high, it is not good, and it will have some negative effects, such as port inheritance and coarse tissue inheritance. It is all caused by overheating. Let's talk about the specific phenomenon of overheating for hot stamping film manufacturers.

1. General overheating: If the heating temperature is too high or the holding time at high temperature is too long, the strength and toughness of the hot stamping film will decrease, the brittle transition temperature will increase, and the tendency of deformation and cracking during quenching will increase.

2. Fracture inheritance: There are overheated materials. After reheating the hot stamping film, there are many controversial theories of fracture inheritance. When cooling, the inclusions will precipitate out along the hot stamping film, and it is easy to break along the hot stamping film when impacted.

3. Inheritance of coarse tissues: heating to a conventional temperature at a slow speed, even lower, the heat of the hot stamping film is still large. This phenomenon is called tissue heredity. To eliminate the heredity of coarse tissues, multiple high-temperature treatments can be used.

The temperature required for the hot stamping film is strictly regulated. If the temperature is lower than this, the printing cannot be completed. There may be uneven printing or not printing, but if the printing temperature is too high, it will If the fabric is damaged, the product produced is definitely unqualified.
