Features	stable quality,high output,wide application range
Drive	Motor

For the molding of rigid PVC products such as PVC profiles/pipes, conical twin-screw extruders have outstanding advantages and are also mainstream processing models. Under the same screw flight structure, although the length of the feeding section of the parallel twin-screw is 60% longer than that of the conical twin-screw, the heat transfer area is 45% smaller. The shear heat generated by the screw, that is, the conical screw is greater than that of the parallel screw, so the plasticizing effect of the conical twin screw on the material in the feeding section is better than that of the parallel screw.

In addition, because the volume of the conical twin-screw decreases continuously during the conveying process, the extrusion effect is enhanced, so that the material can fully contact the screw, so that the conical screw can provide higher energy conversion, so that the pre-plastic effect can be improved. better. In the metering section, the conical twin-screw has a smaller screw diameter, which weakens the shearing effect on the material and generates less shear heat, which just meets the requirements of PVC plasticizing extrusion.
