The screw is a building block structure, and its material is made of special alloy with high strength and wear resistance. The spiral parts adopt complete meshing model principle, three-dimensional design, numerical control processing, smooth surface, high matching accuracy and good self-cleaning. The screw mandrel is an involute spline, which transfers large torque and is convenient for assembling and disassembling screw.

The extruder cavity adopts multi-section building block type. Each cavity can control temperature independently. There are heating and cooling channels in it. According to user's requirements, steam and electric heating can be used and temperature can be automatically controlled.

The main motor, feeder, cutting machine and liquid feeding system of the extruder are all controlled by frequency conversion. The extruder system is controlled by PLC, and the touch screen is controlled by man-machine operation terminal. The picture is clear and intuitive.
