Specific to an extruding machine using PLC as the main control unit. This extruding machine controls the acquisition module by temperature, then operated by the PCU, finally, it operates by the mode of output point control. This leads to inaccurate temperature control, and the cost is high. In the production process, the thickness of the finished product is often uneven. The customer installed the GSM controller which is developed by Winpark for this extruding machine, this controller realizes the automatic control the weight of film blowing machine. By weighting the flow rate of the feed which collected by the sensor, and control the speed of traction according to the change of the flow rate, thereby achieving the control the weight of the blown film. GSM controller has the function of integration automatic calculus, precisely control, safe and reliable. It’s saved labor and improved working efficiency. After comparison, GSM solution has low cost, good performance and short development cycle. Now, WINPARK keeps good cooperation relationship with them.

• function of integration automatic calculus, precise temperature control, easy debugging
• save the installation space, safe and reliable.
• the development process is easier

• Switch multi-channel of input freely
• Extended module support relay output and analog output
• PID auto-tuning function
