Non-Intermeshing Parallel Twin Screw Barrel

Nanhaiya Non-Intermeshing parallel twin screw barrel runs parallel but do not intermesh, reducing shear while maintaining consistent material transport. This configuration prevents excessive heat buildup and preserves material properties. The barrel is made from premium alloy steel, lined with nickel-tungsten carbide, and precision-machined to ensure tight tolerances. It is suitable for polymer compounding, WPC production, and materials that require careful handling during extrusion.

Product Parameter (Specification)

Product Feature and Application

Non-intermeshing barrels are used where low shear and gentle mixing are required. They are ideal for PVC profiles, WPC decking, and sensitive thermoplastics. The barrel allows higher filler ratios while maintaining material integrity and consistent product quality.

Production Details

Each Nanhaiya parallel twin screw barrel undergoes advanced CNC machining and precision grinding. The surface is mirror-finished to minimize friction and improve plastic flow. The screw flight is hardened by nitriding or bimetallic alloy coating for long-term stability.
