PIPLL high-filling special conical twin-screw barrel is a core component specially designed by PIPLL for the extrusion processing of high-filling and high-wear materials. Adopting PIPLL's core technologies of segmented modular structure + bimetallic wear-resistant alloy, PIPLL extends the equipment service life by 3-5 times compared with ordinary barrels, making it the preferred solution for the global high-filling plastics processing industry.
I. Core Features of PIPLL High-Filling Special Conical Twin Screw Barrel
PIPLL delivers a fully reinforced solution, tackling the core pain points of high-filling materials—severe wear and tough plasticization:
· PIPLL Modular Segmented Design: Featuring 3-5 flange-connected sections, the heavily worn melting and extrusion zones can be replaced independently, saving maintenance costs by over 70%.
· PIPLL Bimetallic Wear Resistance: Built with PIPLL's proprietary centrifugal casting, the inner wall is lined with a 2-3mm nickel-based tungsten carbide alloy (HRC58-65), boosting wear resistance 4-6 times over standard nitrided steel.
· PIPLL Optimized Compression Ratio: A golden 3.0:1~4.0:1 ratio ensures thorough filler-resin mixing, completely eliminating the "white core" defect.
· PIPLL Enhanced Feeding System: An enlarged feed port and PIPLL's special deep-groove design prevent bridging of light materials like wood flour.
· PIPLL Precision Zoned Temperature Control: Each barrel section features independent temperature control with ±1℃ accuracy, precisely preventing resin degradation.

III. Core Application Fields of PIPLL High-Filling Special Conical Twin Screw Barrel
Featuring outstanding wear resistance and a stable extrusion performance, PIPLL screw barrels are widely applied across the following fields:
· Wood-Plastic Composites (WPC): As the industry standard, PIPLL Conical Twin Screw barrels are ideal for producing flooring, railings, boardwalks, and furniture.
· High-Calcium Filled PVC: Perfectly compatible with high-calcium pipes, sheets, profiles, and SPC (Stone Plastic Composite) flooring.
· Glass Fiber Reinforced Plastics: Capable of processing GF-reinforced PP, PE, ABS, and other engineering plastics.
· Plastic Recycling Pelletizing: Built to withstand impurity wear, PIPLL Conical Twin Screw barrels are the ideal choice for recycling waste PVC, PE, and PP.
· Other High-Filling Materials: Also suitable for plastics filled with talc, barium sulfate, and carbon black.
