our  system uses the SIEMENS PLC+ SIEMENS frequency converter + touch screen, greatly improves the practicability and accuracy of system. Control system with display and control, alarm and interlock function. Pressure was measured by high temperature melt pressure sensor,temperature measurement using circlip type thermocouple, temperature controller with integrated SSR module. The pressure to control the execution of selection of variable frequency motor. At the same time, set up the pump inlet pressure control loop, and the extruder control system is connected, to achieve closed-loop control of the whole production line.

    Product features: melt pump control system using the PLC Siemens PLC programmable control mode, equipped with advanced man-machine interface, can the pressure, temperature, flow, speedof a full range of control, automatic and manual control functions without switching, control system can well eliminate various factors caused by the pressure fluctuation of the extruder, stability the outlet pressure, melt pump play advantage in terms of maximum precision extrusion.
