Explore our state-of-the-art precision extruders, calibration systems, and downstream processing equipment customized for industrial requirements.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is dedicated to the professional design, high-end fabrication, and global sales of premium plastic extrusion equipment. Leveraging over 25 years of engineering experience and continuous optimization inherited from the original parent enterprise (KINGSWEL GROUP founded in Shanghai in 1999 with Taiwanese expertise), we stand at the forefront of polymer extrusion processing technologies.
We are committed to delivering custom, turnkey production systems that feature high automation, safety, and energy efficiency, helping our clients minimize scrap rates and optimize overall production efficiency.
We combine Taiwanese engineering discipline with mainland China's highly resilient and robust manufacturing supply chain to construct world-class extrusion lines at competitive price points.
The demand for multi-material profiles, multi-lumen tubing, and barrier layers requires advanced rheological engineering and control. Discover the core technologies driving the next generation of co-extrusion machinery.
Custom-designed crossheads and spiral mandrel distributors optimize melt flow velocity across all layers (ABA, ABC, or multi-layer configurations). This mitigates interfacial instabilities and maintains exact wall-thickness ratios.
Our feedblocks enable fast geometric configuration adjustments. Operators can modify layer sequences and thickness ratios with minimal downtime, ensuring superior material yields when handling heat-sensitive polymers.
High-precision gravimetric dosing units monitor material consumption rates in real time. They communicate with the main extruder controller to automatically adjust screw speed and puller velocity for micron-level tolerance management.
In multi-layer co-extrusion (such as PA/EVOH/PA/PE structures for automotive fuel lines or high-barrier packaging), different polymers exhibit unique viscosities and shear-rate profiles. If the velocity profiles do not match at the merge point inside the die, interfacial shear stress will build up, leading to delamination and aesthetic defects like "sharkskin" or melt fractures.
At BAOD, our computational fluid dynamics (CFD) simulation software designs flow channels specifically tailored to your production materials. By simulating shear stress distributions and heat transfer characteristics inside the tool, we guarantee smooth flow convergence. This is critical when extruding materials with highly contrasting melting points, such as PVC combined with thermoplastic polyurethanes (TPU) or fluoropolymers (PVDF).
BAOD provides customized turnkey solutions that comply with sector-specific global standards. We design systems optimized for complex industrial applications.
Automobile development requires light, durable conduits. Our multi-layer co-extrusion lines produce PA/TPV/PVC smooth and corrugated hoses for fuel vapor, engine coolant, and air brake systems. These systems maintain dimensional stability and meet stringent EV heat insulation standards.
Engineered for cleanroom production, our medical-grade co-extrusion lines process PVC, TPU, and PE with extreme precision. They are designed for multi-lumen catheters, anesthetic conduits, and peristaltic pump tubes. These systems feature closed-loop vacuum water sizing to ensure stable OD/ID control.
For modern fiber-optic installations, our lines produce HDPE silicone core tubes (micro-ducts) with low-friction inner layers. By co-extruding a thin silicone slide layer inside the tough HDPE structural wall, cable blowing resistance is minimized, extending maximum installation distances.
Our production base in Jiangsu, China, operates under strict lean manufacturing protocols. By integrating advanced CNC machining centers, precision tool grinding machines, and automated assembly areas, we monitor every step of the production process—from raw steel processing to final assembly testing.
Supply Chain Integration: Located in the Yangtze River Delta, BAOD benefits from China’s leading industrial manufacturing ecosystem. We source premium steel, heat-treatment processes, and electrical components efficiently, passing the cost savings directly to our global customers. This localization ensures rapid parts replenishment and minimizes lead times compared to standard European machinery builders.
Purchasing capital equipment from overseas requires clear guarantees on compliance, safety, and local integration support. BAOD has established an international service model designed to mitigate operational risks for global manufacturing enterprises.
All extrusion machinery is manufactured to comply with EU CE Mark standards, UL configurations for the North American market, and local electrical regulations (including CSA or GOST).
We invite customers to verify their machinery prior to shipment. Real-time video audits or in-person FAT trials are conducted using your specific resins to confirm performance parameters before delivery.
Our engineers support installation, commissioning, and on-site training worldwide. Online remote access modules allow our technical center to diagnose PLC issues and push updates instantly.
Engineered for high-tolerance medical catheters, capillary tubing, and small industrial piping with custom material feedblocks.
Designed for automotive fluid lines, including fuel, cooling, and braking tubes, processing PA6, PA11, and PA12.
High-capacity lines built for ISO Class 8 cleanroom production, ensuring high-speed output and accurate dimensional control.
