BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was founded in 2002, dedicated to designing, manufacturing, and sales of high-precision plastic extrusion equipment.
Based on 18 years of experience designing and fabricating high-quality machinery in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing our modern extrusion manufacturing base in Shanghai in 1999. Today, backed by 25 years of accumulated experience in plastic extrusion design and manufacturing, BAOD EXTRUSION stands as a premier global OEM/ODM technology partner for high-precision industrial, medical, and automotive applications.
Modern thermoplastic polymer processing demands tailored screw geometry, thermal zone stability, and precise melt pump metering. Selecting the correct extrusion line architecture is pivotal to achieving dimensional integrity, high yield, and minimal material degradation across critical industrial polymers.
Designed for steady-state polymer conveyance and shear-sensitive resin handling. Equipped with specialized L/D ratios ranging from 25:1 to 36:1, featuring barrier screw flights, Maddock mixing heads, and grooved feed bushings. Ideal for processing high-density polyethylene (HDPE), polypropylene (PP), and flexible PVC with sub-millimeter outer diameter consistency.
Utilizing multi-manifold dies or co-extrusion feedblocks to layer up to 5 distinct polymers (e.g., PA/Tie/EVOH/Tie/PE). Crucial for manufacturing low-permeability automotive fuel lines, oxygen-barrier medical tubing, and reinforced composite fluid lines where distinct inner chemical resistance and outer mechanical abrasion resistance are required simultaneously.
Custom built for processing ultra-high temperature resins like FEP, PFA, PTFE, and ETFE. Featuring corrosion-resistant alloy screws and barrels made from Hastelloy C-276 or Inconel 625, combined with micro-zone ceramic heaters reaching temperatures up to 450°C. Engineered specifically for high-spec semiconductor tubing, aerospace sleeve, and chemical transport hoses.
Integrated extrusion systems paired with continuous vacuum-assisted or blow-molded corrugated block formers. Capable of generating single-wall and double-wall flexible conduits from PA, PP, PE, and PVC. Designed with high-speed cooling jackets to support output speeds up to 30 meters per minute for automotive wire harnesses and medical breathing tubes.
Engineered for dynamic rubber-plastic seal profile manufacturing. Incorporates inline metal backbone/wire insertion heads, microwave vulc-ovens, and multi-durometer co-extrusion capability (combining rigid PVC base with flexible TPV/EPDM sealing lips). Widely utilized in global Tier-1 automotive door weatherstripping lines.
Extremely heavy-duty single-screw extrusion designs optimized for UHMWPE processing. Featuring hyper-torque planetary reduction gearboxes, forced-feed cooling channels, and hardened wear-resistant barrel liners. Resolves severe melt viscosity issues to manufacture wear-resistant guide rails and sliding seals.

All BAOD custom extrusion machinery features integrated closed-loop melt pump control and ultra-precise laser outer-diameter gauge feedback. The optical measurement feedback instantly adjusts the haul-off speed of our TKB Belt Pullers or TKC Crawler Units, keeping wall thickness deviations well within ISO 13485 and IATF 16949 regulatory limits.
The demand for custom extruders has expanded far beyond simple pipe manufacturing. High-value manufacturing hubs across North America, Europe, East Asia, and the Middle East require tailored extrusion lines that comply with exact physical, mechanical, and biological standards.
Single and multi-lumen central venous catheters, IV drip tubes, peristaltic pump tubes, and balloon catheters extruded inside ISO Class 8 cleanrooms.
Multi-layer PA12 cooling lines for EV battery packs, turbocharger air hoses, fuel vapor lines, and high-precision TPV door seals.
High-purity FEP/PFA tubing manufactured to withstand aggressive acids, solvents, and extreme thermal conditions without leaching trace ions.
Over the past decade, Chinese extrusion machinery manufacturers have transformed from basic equipment assemblers into global innovators of high-precision extrusion systems.
Integrating ultrasonic and optical measurement sensors directly into PLC controllers. Machine learning algorithms predict melt swell and automatically adjust motor torque and haul-off speed in real time, virtually eliminating raw material waste.
Optimizing screw flight profiles to handle shear-sensitive bio-based resins (PLA, PHA) and post-consumer recycled (PCR) materials without thermal degradation, maintaining consistent tensile strength across extruded profiles.
Replacing traditional gearboxes with high-torque direct-drive synchronous motors and ceramic induction heating bands, reducing power consumption by up to 25%–35% while lowering shop floor noise.
