Custom Plastic Extrusion Equipment Factory & Engineering Systems

Extrusion screw geometry must directly match the specific rheology and thermal sensitivity of your polymer. Polyolefins (HDPE/PP) benefit from barrier flight designs with Maddock mixing heads to ensure uniform shear melting without overheating. In contrast, sensitive engineering polymers like rigid PVC or fluoropolymers demand low-shear single screws with nitrided or bimetallic alloys to avoid chemical degradation. Our engineering department tailors L/D ratios (ranging from 25:1 to 38:1) and compression profiles strictly based on your resin grade and target throughput.

Consistent wall thickness requires multi-stage stabilization: (1) high-precision melt pump integration to dampen screw surging down to ±0.5%; (2) cross-head die flow channel design optimized through computational fluid dynamics (CFD) to prevent stagnation zones; (3) ultra-stable vacuum sizing with electronic proportional water-level/vacuum controllers; and (4) multi-axis ultrasonic gauges tied via closed-loop algorithms directly into the servo puller speed system.

Prior to shipping, every complete extrusion line undergoes comprehensive FAT testing in our Jiangsu facility. We encourage clients to ship their specific raw resin compounds. We conduct a continuous multi-hour production run, measuring OD/ID dimensions, wall uniformity, cut edge cleanliness, and line speed stability. Clients receive a comprehensive quality audit report along with full high-definition video logs and electrical safety certifications before sign-off.

Yes. Our stand-alone vacuum calibration tanks, high-speed belt pullers, fly knife rotary cutters, and corrugated pipe formers can be tailored to retrofit into existing manufacturing lines. We customize line heights, track directions, control interface protocols (analog signals, Profinet, or digital relays), and synchronized communication so your plant achieves higher reliability without a total line replacement.
