Restricted Forming

In restricted forming, the plasticization, filling, and curing reactions of the material are all carried out in the mold. In this process, the primary focus is on

Control three technical parameters, namely mold temperature, forming pressure, and forming time.

In restricted forming, the mold usually needs to be preheated to140one18090Due to the limitations of plastic in terms of time, reduction rate, and plastic parts

The electrical function and appearance of the mold are directly related to its temperature. The mold temperature is too low, which increases the resistance of plastic movement and improves its mobility

Deterioration, even with improved forming pressure, it is difficult to fill the mold cavity;The mold temperature is too high, which accelerates the solidification of the plastic, but the internal plastic

The material solidifies slowly, and the released gas is not easy to escape, causing swelling or bubbling on the surface of the plastic part.

Forming pressure is an important condition for plastic parts to obtain a shape that is exactly the same as the mold cavity;In addition; Because in the process of forming

In the middle, there are low molecular weight volatile compounds that can resist the pressure caused by gas and prevent plastic parts from foaming. Forming pressure

The variety of filling materials, mold temperature, preheating method, and shape of the plastic parts may vary.
