Abstract
 Applies the PLC control in the injection molding machine production line, has the structure to be simple, the programming is convenient, the operation is flexible, the use security, the work are stable, the perform reliably and the antijamming ability strong characteristic, is one very effective automatic control way, is casts the production to realize, the low cost, the high grade automated production development direction highly effective. 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.
