Application of Delta’s PLC in Positioning in Injection
Automation equipment often requires the measurement of length or distance. There are various sensors of different types or working principles used for measuring length and distance. In terms of Delta’s PLC applied in the plastic injection machine, the current mold opening position or injection position are measured by the resistance ruler, and the variable output signal 0~10V enters the PLC analog input module. The PLC program then decides whether to open or close the position of the mold or decides the injection volume in the injection phase.

Application of Delta's Temperature Controller in Injection

Temperature control plays a significant role in the injection engineering. When the temperature of the plastic material is in good control, the fluidity of the melted plastic will be improved, and the filling status and the molding efficiency of the final product will also be enhanced.

Delta's DTC series temperature controller controls the temperature of the plastic injection machine in sections. The sensors are installed in the temperature sensing hole in each section, and Delta's human machine interface conducts the parameter setup, and DTC does PID control. On the other hand, the temperature of the mold directly affects the quality and molding efficiency of the final product, which makes the injection molding the key phase. Delta's DTA series temperature controller has been applied in the temperature control in air-cooled mold temperature controllers and vertical injection molding machines.
