Discover our primary line of high-performance plastic extrusion machines engineered for medical, automotive, and industrial grade components.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was established in 2002. We specialize in designing, manufacturing, and servicing premium plastic extrusion systems. Integrating over 18 years of technical expertise from Taiwan via our original parent company, KINGSWEL GROUP (which pioneered mainland operations in Shanghai in 1999), we deliver highly automated, ultra-precision production systems to global markets.
Our research and development program focuses on four primary engineering vectors:
Maintaining micro-level outer diameter (OD) and wall thickness tolerances.
Energy-optimized screw-and-barrel geometries maximizing melt output.
Smart, closed-loop feedback systems featuring Siemens PLC modules.
Integrated overload safety relays, thermal guards, and emergency overrides.
Processing Polyurethane (PU/TPU) poses complex rheological challenges due to its shear-sensitive molecular structures, narrow window of processing temperatures, and hygroscopic nature. Our systems are engineered to address these characteristics.
Our extruders feature 38CrMoAlA nitrided steel screws, optimized with an L/D ratio of 28:1 to 32:1. This geometry guarantees homogeneous melting with minimal shear heat generation, preventing polymer degradation during TPU processing.
Constructed from SUS304 stainless steel, our vacuum sizing tables feature automatic water temperature control and multi-axis alignment. These elements help maintain accurate tube roundness and diameter.
Utilizing dual-axis synchronizers and high-resolution encoder feedback, our pullers apply consistent pulling tension. This helps prevent slip or deformation on soft TPU and medical-grade lines.

Engineering Details →From sub-millimeter medical tubes to reinforced industrial air hoses, our lines are optimized for diverse manufacturing sectors.
Modern vehicle engineering demands materials capable of withstanding chemical contact, temperature fluctuations, and structural vibrations. Thermoplastic polyurethane (TPU) hoses processed on our lines are commonly used for air brake systems, fuel lines, fuel tank vents, and cable protective conduits. Our multi-layer co-extrusion technology enables manufacturers to fuse PA, TPU, and barrier layers, enhancing chemical resistance and safety.
Medical-grade TPU is widely specified for catheters, IV tubes, and enteral feeding tubes due to its biocompatibility, flexibility, and strength. BAOD Med-Series extrusion lines operate within class-10,000 cleanrooms. Utilizing micro-extruder designs, vacuum calibration, and gravimetric dosing systems, these lines produce multi-lumen and thin-wall tubing with OD tolerances within ±0.02mm.
Industrial applications require flexible pneumatic lines that resist mechanical wear, oil, and kinking. Our TPV/TPU composite hose lines integrate inline spiral yarn winding or knitting units. This design applies reinforcing fibers between inner and outer extruded polyurethane layers, allowing the hoses to withstand working pressures up to 60 bar.
Our HDPE/Silicone core micro-duct lines are configured to extrude low-friction sub-ducts for fiber optic cables. The inner silicone layers reduce drag during cable installation, enabling longer blowing distances in telecom network deployment.
Operating a 16,000 m² factory in Jiangsu allows BAOD EXTRUSION to combine advanced Taiwanese engineering methodologies with China's manufacturing ecosystem.
In-house CNC machining of die heads, screws, and sizing sleeves guarantees quality control and reduces reliance on external vendors.
Our localized supply chain helps us manufacture and ship customized extrusion lines up to 40% faster than European counterparts.
Every line undergoes trial runs under simulated production conditions using raw materials supplied by the customer prior to shipment.
We design our systems to accommodate emerging plastic processing technologies and materials, including bio-based TPUs and smart factory integrations.
By pairing laser outer diameter gauges and ultrasonic wall thickness sensors with PLC control systems, our extruders automatically adjust screw speed and puller tension in real time to maintain dimensional stability.
We configure our screw profiles and barrel temperature zones to process bio-based, recycled, and biodegradable thermoplastic elastomers, helping manufacturers meet corporate carbon-reduction targets.
Our multi-layer crosshead die structures permit co-extruding up to five layers, allowing manufacturers to combine structural backing, barrier materials, and soft touch finishes in a single run.
We support international procurement teams with comprehensive documentation, compliance certifications, and global engineering deployment.
All mechanical and electrical components are configured to meet local safety and environmental standards, including CE marking, UL electrical compliance, and ISO 9001:2015 quality standards.
Our PLC units can be equipped with secure VPN gateways. This enables our engineering team in China to diagnose issues, update PLC programs, and assist with optimization remotely.
Our commissioning engineers travel globally to install equipment, calibrate dies, and train local operations staff, helping shorten the path to full production status.
Review typical engineering answers covering material handling, hardware tolerances, co-extrusion capabilities, and order lead times.
TPU is highly shear-sensitive; excessive shear forces break down the polymer chains, leading to loss of physical properties and defects like bubbles or gel spots. A medium L/D ratio (28:1 to 32:1) combined with barrier screws ensures homogenous melting at lower temperatures, keeping shear heat to a minimum.
We combine gravimetric raw material dosing, stable melt-pump pressure controls, a vacuum sizing chamber featuring sensitive differential pressure regulators, and high-precision laser diameter gauges. This integration enables real-time adjustments to maintain tolerances within ±0.02mm.
TPU is hygroscopic and will absorb moisture from the air, causing hydrolysis during extrusion, which results in internal voids, surface defects, and poor physical properties. Raw TPU must be dried in a desiccant dryer to a moisture content of less than 0.02% before processing.
Yes. Our heating control loops feature solid-state relays paired with PID microprocessors, maintaining barrel temperatures within ±1°C. This allows operators to run bio-based and biodegradable polyurethane materials with narrow processing temperature windows successfully.
Standard lines are typically completed and tested in 60 to 75 days. Heavily customized lines, such as those featuring multi-layer co-extrusion heads or inline braiding systems, typically require 90 to 120 days from drawing approval to final testing.
We offer dual commissioning paths. Our field service engineers can travel to your facility to handle setup, die tuning, and staff training. Alternatively, we provide complete video manuals, wiring schematics, and remote diagnostic sessions for local integration teams.
