Core Technical Advantages — PIPLL Engineered
· Special Screw Geometry for Extreme High Filling: PIPLL adopts a 30D optimal L/D ratio for full resin-filler blending, supporting up to 100 phr calcium carbonate. Gradient low-shear design prevents PVC degradation, cuts heat stabilizer use by 10%, and enables stable pulse-free feeding, ideal for WPC production.
· Stainless Steel Double-jacket Cooling: PIPLL equips high-efficiency air cooling, reducing heat loss by 50% and keeping temperature accuracy within ±0.8℃.
· Graded Wear-resistant Solutions: PIPLL offers tailored options—38CrMoAlA nitrided steel for standard use, Ni60 alloy for medium wear, and WC-coated components for heavy wear, delivering 3-5× longer life than nitriding.
· Modular Precision Design: PIPLL uses segmented modular barrels for easy replacement, with ultra-precision machining ensuring screw concentricity ≤0.015mm and meshing clearance ≤0.02mm, for smooth, low-noise operation.
