2. How does conical twin screw extruder work?

We have driving motor connect with gearbox, and one side of gearbox which connected to screw and barrel, we use the counter rotation to push the raw material go ahead. The conical twin screwed is covered by barrel, and barrel is covered by the heater, we use the heater to heating screw and barrel, it will melt the raw material, and forming product by pressure in the mould.

3. What products the conical twin screw extruder used to make?

The conical twin screw extruder is the main extrusion part in the production line, we need connect with down-stream machine to formed the whole production line.

We can used the conical twin screw extruder to produce PVC solid pipe, PVC corrugated pipe, PVC window profile, PVC ceiling, WPC wall panel, PVC wall panel, PVC marble sheet, Stone-plastic floor, PVC foam board, PVC granules and so on.
