High-speed, smart-control extrusion and handling lines designed for stringent industrial compliance, automotive routing, and medical device standards.
Processing Perfluoroalkoxy (PFA) presents mechanical and metallurgical challenges that standard extruders cannot handle. PFA exhibits exceptional thermal stability and chemical resistance, yet at processing temperatures ranging from 350°C to 400°C, fluoropolymers release micro-amounts of highly corrosive hydrogen fluoride (HF) gas. Without specialized machine metallurgy, standard extruder components degrade rapidly, causing catastrophic contamination of the extruded tube.
Our custom PFA tube extrusion lines address this through specialized material science. All melt-contact areas—including the screw, barrel, die head, and calibration tooling—are constructed using premium nickel-based alloys like Hastelloy C-276 or Inconel 625. This prevents chemical degradation of the machinery and guarantees the absolute purity of the output tubing, making it compliant with SEMI F57 guidelines for ultra-pure semiconductor water transport.
For semiconductor wet benches and chemical dosing lines, wall thickness uniformity and inner surface smoothness (Ra < 0.1 μm) are critical. Fluctuations in tube concentricity lead to weak spots susceptible to burst pressures or chemical accumulation.
By incorporating closed-loop laser monitoring linked directly to the vacuum calibration chamber and puller tension, our line achieves a dimension control tolerance of ±0.03 mm on both inner and outer diameters.
This control loop ensures that tube profiles remain perfectly concentric, mitigating the risk of micro-cracking during installation or runtime stress cycles.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is dedicated to the research, development, and manufacturing of precision plastic extrusion equipment. Our engineering foundation stems from 18 years of design and fabrication expertise developed in Taiwan under our original parent company, KINGSWEL GROUP, which established its main Shanghai production base in 1999.
Today, with a total operational history spanning over 25 years, our focus remains on pushing the limits of high-efficiency, highly automated, and safe extrusion processes. Our development roadmaps concentrate on four key pillars:
Our solutions serve key markets worldwide, addressing the needs of high-purity chemical processing, advanced electric vehicle battery cooling lines, and medical fluid transfer components. We maintain strict manufacturing and assembly protocols at our 16,000 square meter plant to ensure that every line meets international requirements.
"By merging Taiwan's precision component standards with mainland China's robust industrial supply chain, we deliver high-performance extrusion machinery that offers long-term reliability and low maintenance costs."
Our primary equipment range covers specialized tubing applications across medical, automotive, and general engineering fields.
The fluoropolymer extrusion market is shifting toward tighter tolerances and integration with Industry 4.0 standards.
As semiconductor lithography nodes advance below 3nm, the tolerance for chemical impurities decreases. Transmitted chemicals must flow through piping systems free of metal ions or micro-contaminants. Consequently, PFA extrusion equipment now integrates with Class 10,000 cleanroom layouts, using closed-loop systems to prevent cleanroom contamination during production.
Industrial operations frequently deploy layered fluoropolymer designs (e.g., PFA over-jacketed with conductive carbon layers or PVDF) to manage static charges in solvent transport lines. Our multi-layer co-extrusion crossheads allow processors to manufacture composite lines with stable layer boundaries, reducing material costs while maintaining the chemical resistance of the inner PFA layer.
Modern extrusion operations increasingly require continuous telemetry. Operating parameters—such as melt temperature, pressure profiles, screw torque, and cooling media temperatures—are monitored and fed directly to SCADA systems via OPC-UA protocols. This allows operators to track production metrics and verify batch-to-batch consistency.
Understanding which fluoropolymer to process depends on the thermal and mechanical profile required. The table below details why PFA remains the primary choice for critical UHP (Ultra-High Purity) applications:
| Property | PFA (Perfluoroalkoxy) | FEP (Fluorinated Ethylene Propylene) | PTFE (Polytetrafluoroethylene) |
|---|---|---|---|
| Continuous Service Temp | 260°C (500°F) | 200°C (392°F) | 260°C (500°F) |
| Melt Processability | Excellent (Thermoplastic Extrusion) | Excellent (Thermoplastic Extrusion) | Poor (Requires paste extrusion/sintering) |
| Chemical Resistance | Universal (Solvents, Acids, Bases) | Excellent, but limited at high temps | Universal (Solvents, Acids, Bases) |
| Inner Roughness Potential (Ra) | < 0.1 μm (Highly smooth) | < 0.15 μm | Rougher due to sintering method |
| Dielectric Strength | High (UHP electrical insulation) | High | Very High |
Our manufacturing base integrates modern CNC machining, quality control testing, and assembly bays. By managing component manufacturing in-house, BAOD minimizes external supply chain risks. We use CNC machining systems to produce extrusion screws, crossheads, and sizing sleeves, ensuring precise control over core tooling tolerances.
Additionally, our local manufacturing setup provides a direct cost benefit without compromising technical performance. We utilize standard European and Japanese automation components—such as Omron PLC controllers, Siemens drives, and Dynisco melt sensors—while handling structural fabrication locally to balance cost and performance.
Global procurement teams face three main challenges when sourcing fluoropolymer extrusion lines: long commissioning lead times, poor tooling durability, and inadequate after-sales technical support. Standard extrusion machinery may fail prematurely when processing corrosive melts, resulting in production downtime.
At BAOD, we address these challenges through structured support protocols:
1. Quality Control Protocols & Factory Acceptance Testing (FAT)
Every extrusion line undergoes test runs with target resins before shipment. We provide operational data, melt flow stability charts, and outer diameter tolerances to verify alignment with buyer specifications.
2. Technical Service & Engineering Support
Our engineering team assists with factory layout design, cleanroom integration, and calibration adjustments for specific line configurations.
