China Plastic Tubing Extrusion Manufacturers & Product Solutions

Unlike generic extrusion workshops that assemble standard components from open markets, BAOD EXTRUSION traces its roots back to 1999/2002 with 18 years of prior Taiwan-based extrusion machine design. Every critical melt-contact component — including barrier screws, multi-layer co-extrusion crossheads, vacuum calibrators, and high-precision haul-off pullers — is engineered in-house inside our 16,000 m² Haian facility. We specialize exclusively in high-precision, small-diameter tubing (0.5mm to 32mm) for automotive, medical, and specialized industrial sectors where tight dimensional tolerances (±0.02mm to ±0.03mm) and low scrap rates are mandatory.

We employ a three-tier closed-loop stabilization system. First, our nitrided and bimetallic screws are designed with specialized mixing heads to eliminate thermal gradients in the polymer melt. Second, our multi-stage vacuum sizing water baths use high-precision proportional vacuum regulators (maintaining vacuum variations under ±0.2 kPa) and closed-loop chilled water temperature loops. Third, we integrate dual-axis or four-axis laser OD gauges and ultrasonic wall-thickness monitors directly with the servo puller. When any dimensional drift is detected, the puller's micro-speed adjusts instantly to pull the tube back to the exact target geometry within milliseconds.

Yes. Fluoropolymers require dedicated metallurgical protection and accurate heating zones due to their narrow processing windows and corrosive outgassing at high temperatures (350°C to 400°C). Our custom fluorine plastic tube extrusion lines utilize barrels, screws, and die heads machined from GH113 or Hastelloy high-nickel super-alloys, paired with ceramic band heaters and solid-state relay (SSR) temperature controls sensitive to within ±0.5°C. This prevents barrel pitting, screw corrosion, and polymer shear burning.

We strongly advocate for material-based validation. Clients are invited to send their specific production resin to our factory, or our engineering team sources identical raw grades. The line is run continuously for a minimum of 4 to 8 hours under full target production speed. Dimensional tolerance readings, linear meters produced, puller tension stability, and sample roundness are recorded. Clients can either inspect the trial in person at our Haian facility or attend an exhaustive interactive video inspection. Machines are only released for packaging after the client signs the official FAT tolerance certificate.

European manufacturers undoubtedly produce high-end extrusion equipment, but their CapEx typically stands at 2.5x to 4x that of a BAOD turnkey line, accompanied by substantial maintenance and replacement parts costs. BAOD combines Taiwan precision engineering standards and globally recognizable core electrical components (Siemens PLC, ABB inverters, Schneider contactors, Omron sensors) with Chinese integrated manufacturing efficiency. Our clients routinely report equivalent CPK values (>1.33) and line speeds, realizing full capital return within 8 to 14 months of commissioning.

To provide a comprehensive technical and commercial proposal, we request: 1) Engineering drawing or specification sheet indicating Outer Diameter (OD), Inner Diameter (ID), Wall Thickness, and allowed tolerances; 2) Exact resin datasheet (polymer grade, MFI, filler/reinforcement percentage, and layer composition if multi-layer); 3) Target line speed (meters/minute) or output capacity (kg/hour); 4) Downstream cutting or coiling requirements; 5) Local plant voltage, frequency (e.g., 380V/50Hz, 480V/60Hz), and compressed air/water supplies.
