Thermal transfer film process analysis

Jan 09,2021

Heat transfer film is a kind of medium material used in heat transfer process, and it is a kind of decorative material that is widely used now. Many good properties such as grinding and heat resistance. Not only the tone of the thermal transfer film is very stable, the pattern is also very novel, so it is very popular.

The application field of heat transfer film is also very wide, divided into MDF transfer film, WPC transfer film, sublimation film, glass transfer film and floor transfer film. By heating the thermal transfer film, the pattern on the thermal transfer can be transferred to other materials that need to be decorated to form a beautiful and high-quality decorative mask. This process is the thermal transfer decoration process. The reason why the pattern on the heat transfer film can be transferred to the building materials that need to be decorated by heating is because the material of the heat transfer film is a polyethylene film, which is divided into four levels. Heating and pressing causes the transfer layer composed of the decorative wood grain printing layer, the base color layer and the surface protection layer to separate from the polyethylene, so that the pattern on the heat transfer film can be transferred to the material to be decorated Above, the operation is simple and easy, and the decorative renderings formed are also very beautiful. This method is also very environmentally friendly and does not generate a lot of harmful gases like previous decorations, and the patterns are also very delicate. The resulting pattern can be maintained for a long time and is very stable.

Due to its special properties, thermal transfer film requires a good grasp of temperature, pressure, and speed to get better results. The hot stamping temperature is generally 140 to 180 degrees, and the temperature must be kept constant. The pressure is generally 4 to 6 kg/cm2. The determination of the speed depends on the area to be dyed. Hot stamping must first determine the speed, followed by temperature and pressure.
