Explore our engineering excellence, custom configurations, and automated processing lines.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), established in 2002, is an industry-leading manufacturer specializing in the research, design, and customization of high-efficiency plastic extrusion systems. Rooted in over 18 years of advanced mechanical engineering and design expertise from Taiwan, our initial operations began under the Kingswel Group in Shanghai in 1999, establishing a strong foundation for precision engineering in mainland China.
Over the past quarter-century, we have steadily expanded our technological horizons to support international medical, automotive, packaging, and chemical engineering markets. By continuously integrating automation with polymer science, we deliver high-speed, multi-layer co-extrusion technologies that fulfill rigorous global standards.

In-depth technical insight into custom multi-layer structural extrusion systems
Effective co-extrusion depends on matching flow characteristics between dissimilar polymers (e.g. TPV, PVC, PA, Fluoropolymers). BAOD design integrates computer-aided simulation flow channels to prevent melt fracture and delamination at the interfaces.
Our custom crosshead dies offer concentric alignment, allowing tight-tolerance wall thicknesses down to ±0.02 mm. This level of precision is necessary for critical applications like multi-lumen medical catheters and high-pressure automotive lines.
Equipped with modern Siemens/Beckhoff PLC control systems, BAOD machines feature dynamic closed-loop monitoring. Continuous parameters adjustments based on laser gauges ensure stable OD/ID ratios throughout long production runs.
Co-extrusion is a key manufacturing technique in modern polymer processing, enabling engineers to combine several distinct material characteristics into one continuous profile or tube. By combining different materials, manufacturers can optimize performance properties—such as barrier resistance, chemical inertness, cost efficiency, and flexibility—within a single, integrated cross-section. Selecting an experienced Custom Co Extruder Manufacturer involves evaluating their engineering capability to handle these complex thermodynamic and physical interfaces.
For example, in the automotive sector, fuel line assemblies rely on multi-layer co-extruded tubes (often PA12/PVDF or specialized elastomer combinations) to minimize fuel vapor emissions while resisting external abrasion and road salt exposure. Similarly, high-performance medical tubing—including multi-lumen catheters—requires precise structural stability across micro-scale pathways. Successfully processing these materials demands tight thermal controls and optimized flow channel designs in the co-extrusion die to manage shear-induced degradation.
Sourcing specialized co-extrusion machinery from China offers substantial logistical, technical, and economic benefits. The country's deep manufacturing ecosystem allows companies like BAOD EXTRUSION to source high-grade steel alloys, precision motor drives, and advanced electronic components with minimal transit delays. This concentration of local suppliers reduces total lead times compared to Western European counterparts.
Furthermore, the concentration of polymer research institutes and downstream processing industries in China drives rapid design iteration. When custom systems are requested, our engineering team utilizes local component networks to source high-efficiency heating elements, custom cooling systems, and specialized extrusion tooling. The result is custom co-extrusion lines that balance performance and cost, helping global buyers achieve a high return on investment.
| Polymer Profile Configuration | Target Application Industry | Tolerances Achievable | Key Process Feature |
|---|---|---|---|
| Multi-Layer PA/PE/PP Hose | Automotive Fluids, Fuel Systems | ±0.03 mm | High-pressure resistance, chemical barrier layer integration |
| TPV/PVC Co-Extruded Seals | Automotive & Construction Weatherstripping | ±0.05 mm | Dual-durometer soft/rigid composite extrusion |
| Precision Medical Catheter Tubes | Minimally Invasive Interventions | ±0.01 mm | Micro-lumen configuration, biocompatible polymer handling |
| Fluoropolymer (FEP/PTFE) Tubes | High-Temp Chemical Transmissions | ±0.02 mm | Corrosion-resistant screw/barrel coatings, precise heating zones |
For international buyers, the performance of a co-extrusion line relies heavily on the availability of post-sales support and regulatory compliance. Ensuring compliance with global directives—such as the EU Machinery Directive (CE Mark), UL/CSA electrical standards, and ISO 9001:2015 quality management procedures—is standard practice for BAOD EXTRUSION.
To support global installations, we provide comprehensive documentation package services, including installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation. We also offer remote diagnostic interfaces on our PLCs, allowing our engineers to assist with troubleshooting, parameter optimization, and software updates regardless of your factory's location.
