Injection molding machine, extruder / extrusion production line, blow molding machine, blowing molding machine, blow molding machines, shredders, plastic auxiliary equipment such as including plastic machinery varieties, the injection molding machine, extrusion machine / extrusion production lines and blow molding machine products accounted for more than 80% of the total output value of plastic machinery, injection molding machine accounted for more than half of the sum of the three types of machinery.

To CTSC-200PLC in pet preform injection system application, for example, injection molding machine control the content of main organic barrel temperature, mold temperature, injection pressure, injection speed, Paul pressure, back pressure and position control. In the control device, the mini PLC programmable logic controller to control system of injection molding machine, to achieve, including the whole process of position control, speed control, pressure control, temperature control, fault control and real-time display of injection molding a variety of control, can greatly improve the quality of plastic products, to improve the economic benefit.
Temperature control using EM231 PID TrustPLC CTSC-200 series temperature control module PLC. The module specially for temperature control application quantity body custom, built-in PID temperature control algorithm, users do not need programming can realize complex closed-loop temperature control, reduce the computing burden of CPU, control the speed faster, the effect is more outstanding.

To PLC UniMAT in plastic extruder control system applications, for example, extruding machine control system comprises an extrusion system, transmission system, heating and cooling system and automatic control system. The automatic control system includes touch screen, PLC, pressure sensor, temperature sensor and some executive devices. Automatic control system is a human and machine interface, all of the parameters of the machine must be set here, monitoring and control of the machine and the start and stop of the machine. The automation process and reliability of a machine is reflected here.
