The injection molding skill of IML is to put the silk-printed and hot-pressed PET film into the injection mold. After the injection process of ABS material, the PET film can be pressure-molded with the ABS material in the cavity of the injection molding mold. The pressure-preserving and cooling form an outstanding ABS shell shape, and the screen-printed PET film is evenly covered in the mold to cover the outer surface of the ABS component shell, so as to realize the IMD in-mold molding skill product in the true sense.
The difficulties and points of this skill are roughly the following:
The gate orientation of the mold and the correctness of the mold;
ABS material activity direction and pressure temperature demand, pressure holding time setting;
Modular temperature control;
Precise positioning and operation of the PET film in the film;
The need for ABS pellet transport to purify the environment;
The operation method of the operator and the process before and after the mold;
Clean process control (refer to yourself, PET film and injection molds, etc.).
