Process control technologies in precision injection moulding

摘要

The control architecture of injection moulding machine consists of machine control, state variable control and set print control. Machine control ensures a specified packing pressure at the melt inlet. State variable control regulate the cavity pressure more precisely based on feedback of measured pressure inside the mould. The Set print control is used to adjust the specified cavity pressure. All these control processes help in achieving satisfactory quality of moulded part, when machine executes the programmed machine inputs.
