PIPLL specializes in high-precision compatible screw barrels for all WEBER models, manufactured strictly to original specifications for perfect drop-in replacement. PIPLL delivers tailored solutions based on your operating conditions, formulations and production needs, cutting procurement costs and shortening lead times.
Core Technical Advantages (Strictly Following Original Design Standards)
PIPLL Industry-Leading Recyclate-Specific Wear Resistance System
· WC-Ni Bimetallic Liner: 2-3mm centrifugally cast tungsten carbide liner (HRC 65-68), 5x more wear-resistant than standard nitrided steel
· Armored Screw: PTA plasma surfacing WC flights with ≥250MPa bonding strength, chipping and wear resistant
· Low-Shear Gradual Compression: 2.0-2.8:1 compression ratio, 35% lower shear, prevents PVC degradation and reduces stabilizer usage by 10%
· Deep Channel Positive Conveying: Volumetric pulse-free feeding, stably handles 60-80 phr calcium carbonate formulations
PIPLL German-Standard Precision Manufacturing
· Screw concentricity ≤0.015mm, meshing clearance ≤0.02mm, operating noise ≤78dB
· All contact surfaces mirror-polished (Ra ≤0.4μm), no dead spots, easy to clean
· Comprehensive pre-shipment testing: material spectroscopy, hardness, concentricity and meshing clearance
PIPLL Custom Service Advantages
· ✅ High-precision drop-in replacement for all WEBER DS series models
· ✅ Wear resistance upgrades and structural optimization tailored to your formulations
· ✅ Machine retrofitting: capacity improvement, process optimization and wear enhancement
Main Application Areas (PIPLL Full-Scenario Coverage)
1.PVC Window Profiles (45%): uPVC windows/doors, guardrails, moldings. Global market share >30%, yield ≥96%. Models: DS 72/22, DS 85/26, DS 116/32
2.PVC Pipes (25%): Water supply/drainage, sewage, electrical conduits. Wall eccentricity ≤0.3%, cost reduction >20%. Models: DS 72/22, DS 85/26, DS 92/26
