Explore BAOD Extrusion's high-efficiency custom solutions engineered for precision automotive tube and pipe manufacturing.
As the global automotive industry experiences an unprecedented transition toward hybrid and full Electric Vehicles (EVs), fluid management systems are under extreme thermal, chemical, and pressure stress. Polyphthalamide (PPA), a semi-crystalline aromatic polyamide, has quickly replaced traditional materials like Nylon 6, Nylon 66, and metals. PPA provides exceptional resistance to high-temperature coolant mixes, battery heat-sink fluids, engine oils, and aggressive hydrocarbons.
Extruding PPA is complex. Its melting temperature (300°C to 330°C) is significantly higher than that of standard PA12 or PA6. Consequently, it requires extremely precise thermal controls, optimized screw geometry (L/D ratios ranging from 28:1 to 32:1), and corrosion-resistant bimetallic liners to prevent thermal degradation and chemical wear. Designing a reliable PPA extrusion system requires significant experience, a deep understanding of polymer rheology, and precise structural engineering.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is a pioneer in manufacturing high-efficiency plastic extrusion lines. With engineering roots established in Taiwan through the original parent company KINGSWEL GROUP since 1999, BAOD transitioned its main manufacturing base to Shanghai and subsequently expanded to its current 16,000m² state-of-the-art facility in Jiangsu. With over 25 years of R&D expertise, BAOD specializes in precision extrusion lines, multi-layer co-extrusion technology, and process automation with built-in safety controls.
How China's leading automotive tube extrusion factories serve global markets while ensuring compliance and localized technical support.
China's extrusion machine factories utilize a robust regional industrial ecosystem. Because components like precision gears, servo motors, electrical parts, and hydraulic elements are sourced locally, we can significantly reduce production times. We combine high-quality bimetallic steel alloys with components from globally trusted brands (Siemens, ABB, Omron, Schneider) to provide high-quality extrusion lines at competitive pricing.
Exporting complex high-temperature PPA extrusion equipment requires strict compliance with international manufacturing safety guidelines. BAOD ensures compliance with standard international regulations, including CE Certification for European markets, UL listing options for electrical cabinets in North America, and compliance with the ISO 9001:2015 Quality Management system. This ensures our machines can integrate smoothly into automated Tier-1 automotive manufacturing plants.
To support global procurement teams, BAOD offers structured localization assistance. We provide installation, calibration, and commissioning services through regional service partners in Europe, the Americas, and Southeast Asia. We also support remote diagnostics using secure VPN connections, allowing our engineering team to troubleshoot, adjust PLC parameters, and optimize settings directly from our headquarters.
Understanding the transition to complex multi-layer co-extrusion technology for electric and internal combustion engines.
The demand for single-layer PA tubes is shifting toward co-extruded multi-layer systems. Modern cooling circuits require PPA on the inner layer (for high temperature and coolant resistance), combined with adhesive binders, barrier layers (such as EVOH for fuel lines), and external PA12 layers to resist stone impacts and environment-induced stress cracking.
BAOD is at the forefront of this trend, offering 3-layer, 5-layer, and custom multi-layer extrusion systems equipped with gravimetric feeding stations that control raw material consumption down to the milligram.
