Product Features

Unique Advantages, Material Characteristics, and Process Know‑How

• Wide processing window for rigid and semi‑rigid PVC, supports recycled PVC (up to 30%+) and co‑extrusion cap layers/seals for enhanced UV and scratch resistance.
• Compatible with Ca‑Zn stabilizers, RoHS/REACH‑compliant formulations, and low‑smoke halogen‑free options; optimized screw geometry ensures thorough plastication and low shear.
• Precision melt management and low‑pulsation metering minimize flow marks, improve gloss, and stabilize dimensions on complex PVC profiles.
• Modular tooling with quick‑change die rails shortens setup time; PID‑controlled multi‑zone heating (±0.5°C) ensures repeatable quality across SKUs.
• Energy‑saving drives, VFD‑controlled pumps/blowers, and insulated barrel zones reduce specific energy consumption while maintaining output.

Core Equipment Highlights

• SJZ55‑110 Conical Twin‑Screw Extruder: high torque, strong feeding, bimetallic barrel and wear‑resistant screws for longevity in filled/recycled formulations.
• 4.5 m Stainless‑Steel Vacuum Calibration Tank: multi‑zone vacuum, dual‑mode cooling (water curtain + fine mist) for sharp edges, straightness, and minimal warpage.
• Belt Haul‑Off Machine: closed‑loop speed control and soft belt surfaces protect delicate profiles and ensure constant line speed.
• Lift‑Up Cutting Saw: burr‑free cutting, accurate length control; supports inline length metering and inkjet coding for end‑to‑end traceability.
