Shanghai Daoqin Plastics Co., Ltd.

injection shot pressure setting main/primary is control pressure make 足以推动 screw to setting injection shot speed degree requirements. due to types plastics features different, flow difficult easy degree different, types material temperature degree different, degree 也会发生变化, product different, injection molding parts mold design, mold temperature different make material flow formed retardant force 改变, need in types types different lower 维持 同一 injection shot speed degree, 就 改变 injection shot pressure, make 克服熔胶 flow formed retardant force. injection shot pressure and maintain pressure different, injection shot pressure main/primary effect/influence is stage/phase, maintain pressure effect/influence is cooling stage/phase.
