Conical Twin Screw Extruder
The conical twin screw extruder is particularly useful for manufacturing plastic profile products using high calcium PVC powder as the raw material. Compared to a conventional single screw extruder and parallel twin screw extruder, the anisotropic conical twin-screw extruder has a large, unique feeding area, a high compression ratio, a higher shear and mixing efficiency for material in the longitudinal and transverse axis, and better plasticizing characteristics.

Advantages of conical twin screw extruder
- Equipped with a large feeding area and high compression ratio, the conical twin screw extruder is ideal for processing PVC powder.
- Longitudinal and transverse shear forces applied via the screws ensure the conical twin screw extruder is more efficient.
- The effective exhaust unit ensures products feature an excellent surface finish.
- A nickel based alloy bimetallic oval liner extends the extruder’s service life.
