The PLC controller

is the heart to automize the startup, production and shutdown of your extrusion line in conjunction with melt pump. All analog and digital IN and OUTPUT will be supervised, limited, interlocked and controlled with the eprotec m-pac system for extrusion or in compounding.

In compounding mode,

the extruder will have constant speed for its perfect application. The pump speed will follow according the inlet pressure control.

In extrusion mode,

the melt pump will have constant speed for a certain capacity to guarantee the constant flow of polymer. The extruder speed will smoothly follow the inlet pressure control.
