Color mold injection molding products to our lives has brought great convenience, two-color mold injection process is not being well known, then the injection molding process step is what is it? Here Shenzhen Kai Rui Technology Co., Ltd. will be with you to explain the process step of injection molding.

Chong Kai Rui Technology pointed out that a two-color mold injection molding process is to go through a very complex multi-step, in general it can be divided into two steps:

The first step is to fill the stage. We want a closed mold is filled at its beginning, until the cavity is filled to 95% of the time for the best. During the injection speed should be controlled within a reasonable range, typically the shorter the filling time, the higher the efficiency of molding.

The second step is the packing phase. Filling phase be made the first step, as the packing stage, the basic is the last step. This stage does is put constant pressure, the melt compacted in this way, the density of plastic reinforced plastic shrinkage resistance. This stage is held until the end of the plastic molding, curing sealing up to the gate in order to achieve the best results.
