  • Product Detail

Our PVC screw barrels are engineered for optimal performance in the extrusion of PVC products. Featuring high wear resistance and superior plasticization, these screw barrels ensure consistent output and quality. Ideal for producing PVC pipes, profiles, sheets, roof tiles, flooring, marble sheets, foam sheets WPC, SPC and compoud pelletizing. our PVC screw barrels are designed to enhance productivity and minimize downtime.

Types of PVC Screws

  1. 1. Equidistant Unequal-Depth Single Screw Designs
  2. 2. Counter-Rotating Parallel and Conical Twin Screw Barrels
  3. 3. Co-Rotating Parallel and Conical Twin Screw Barrels

PVC Screw Design Principles

  1. 1. Low Shear: Prevents overheating during extrusion.
  2. 2. Corrosion Resistance: Essential for durability.
  3. 3. Strict Control for Injection Moulding: Ensures high-quality outputs.

Manufactured by HUACHEN Screw

Our PVC screw barrels are specifically designed for high performance in various PVC applications:

Rigid PVC Pipes, Profiles and Sheets

  • – Conical twin screw extruders are widely used for forming rigid PVC products. They offer superior plasticization due to their structural design and energy conversion efficiency.

PVC Compound Pelletizing

  • – Counter-rotating parallel and conical twin screw machines are commonly used. Co-rotating parallel twin screws are ideal for PVC modification. Single screws are suitable for low capacity and quality requirements.

PVC Injection Moulding

  • – PVC, being highly viscous and corrosive, requires screws with chrome-plated surfaces and corrosion-resistant features. Ensuring good plasticization with low shear heat generation is crucial.
