Co-Rotating Parallel Twin Screw Barrel

Nanhaiya Co-Rotating Parallel Twin Screw Barrel design allows both screws to rotate in the same direction, producing strong intermeshing and continuous conveying action. This ensures high throughput and uniform melting, making it ideal for compounding, pipe extrusion, and sheet production. The barrel is crafted from premium steel and lined with nickel-based tungsten carbide alloy to resist wear and corrosion. Each barrel is finely machined for precise clearance, ensuring smooth rotation, consistent pressure, and reduced mechanical vibration.

Product Parameter (Specification)

Product Feature and Application

Nanhaiya parallel twin screw barrel features optimized channel design for enhanced melt uniformity, double-alloy protection for longer service life, and fine machining that ensures consistent plastic flow.It is widely used for PVC pipe, door, and window profile extrusion. The bimetallic alloy structure significantly improves wear resistance, making it suitable for high-fill and recycled materials.

Production Details

Co-rotating barrels provide excellent plasticizing, mixing, and conveying performance. They are widely used in PVC/WPC profile extrusion, pipe and sheet lines, and high-speed compounding operations. The design accommodates high filler content and recycled material, delivering consistent quality and minimizing product defects.
