Not only caused the injection molding product the quality and the quality obtained the strict guarantee; Moreover also greatly raised the production efficiency and reduces worker's labor intensity, has the very good economic efficiency and the social efficiency. This article is uses in PLC to step-by-step along controls the instruction this methods design one kind both the security and the practical plastic injection molding automatic formation system. key word: PLC hydraulic cylinder solenoid valve injection molding machine
