Engineered for strict tolerance control, thermal stability, and maximum material throughput.
Polyvinyl Chloride (PVC) is one of the most versatile yet thermally sensitive polymers in global industrial manufacturing. Due to its structural characteristics, achieving high precision in PVC extrusion demands an accurate equilibrium of thermal management, shear optimization, and exact mechanical design. Extrusion of rigid PVC (PVC-U) and plasticized PVC (PVC-P) requires distinct engineering approaches to prevent degradation, maintain dimensional stability, and achieve optimal physical properties.
Unlike polyolefins, PVC possesses a narrow processing temperature window. When subject to excessive heat or shear, the carbon-chlorine bonds degrade, releasing hydrochloric acid (HCl), which catalyzes further polymer breakdown. High-precision extrusion lines overcome this constraint by implementing:
Accurate compensation for viscoelastic die swell ensures profiles conform to exact client tolerances upon exit.
Multi-zone PID loop control prevents thermal peaks, eliminating raw compound degradation during continuous runs.
Auto vacuum sizing tanks ensure consistent cooling rates to prevent residual thermal stresses and warping.
High-quality PVC extrusion is as dependent on chemical formulation as it is on mechanical design. Standard blends utilize Calcium-Zinc (Ca-Zn) or organic stabilizers to meet compliance regulations (REACH/RoHS), replacing legacy lead-based systems. Lubricant balances, incorporating both internal (e.g., fatty acid esters) and external lubricants (e.g., oxidized polyethylene waxes), regulate plasticization rates and metal release within the extruder barrel, ensuring uniform polymer melting and consistent output.
Over two decades of precision engineering legacy, originating from robust Taiwanese design standards.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to the development, manufacturing, and sales of high-performance plastic extrusion systems. Rooted in 18 years of design and manufacturing experience in high-precision machinery in Taiwan under our parent group, KINGSWEL GROUP, the company established its major production base in Shanghai in 1999, later transitioning into a highly modern plant in Jiangsu.
For 25 years, our engineering focus has remained on four core technical values: high precision, high efficiency, high automation, and equipment safety. Our equipment serves critical industries including medical devices, automotive manufacturing, and consumer electronics.
Our ongoing collaboration with material compounders and research institutions allows us to design tailored extrusion screws for complex compounds, including fluoropolymers (FEP/PTFE), engineering plastics (PA/POM/PBT), and thermoplastic elastomers (TPV/TPU), alongside traditional PVC systems.

Our dedicated extrusion lines engineered for global industrial demands.
Our high-speed extrusion lines are optimized for specialized industrial sectors that demand adherence to regulatory and performance benchmarks.
High Speed PVC Medical Tube Extrusion Lines operate in Class 100,000 cleanrooms. To prevent particulate contamination, the system incorporates non-contact laser diameter measurement, closed-loop vacuum calibration adjustment, and medical-grade stainless steel tooling. These lines handle DEHP-free plasticized PVC with excellent process stability, providing OD/ID tolerances within ±0.02 mm.
For components like glass run channels, window belt lines, and door weather seals, our lines handle co-extrusion of up to three materials simultaneously. This incorporates rigid PVC substrates for structural mounting, flexible PVC or TPV profiles for sealing, and slip-coat coatings (TPV/Silicon) to reduce glass friction. Our TPV, PVC Automobile Sealing Strip Extrusion Line ensures proper fusion across polymer interfaces and controls the shrinkage of co-extruded materials.
From single-wall corrugated PA/PE/PP/PVC conduits to transparent PC/PMMA optical lampshades, our lines operate at high linear speeds while maintaining optical clarity, physical strength, and flame-retardant performance. Specialized downstream units, such as the High Speed Corrugated Pipe Extrusion Line, feature mold blocks designed for continuous forming at elevated speeds.
The global extrusion industry is shifting toward digitalization, decarbonization, and closed-loop process control. BAOD EXTRUSION remains ahead of these trends by actively integrating advanced controls and mechanical updates into our standard product configurations.
Integrating real-time sensor data with extruder speed and puller tension loops to dynamically correct dimensional deviations.
Developing screw and die geometries capable of processing PCR (Post-Consumer Recycled) PVC and bio-based plastics.
Replacing traditional heater bands with energy-saving electromagnetic heaters and implementing high-efficiency permanent magnet motors.
Our focus on real-time wall thickness and concentricity monitoring utilizes ultrasonic sensors integrated within the water cooling bath. By monitoring changes in wall thickness during processing, the control software provides adjustments to the die positioning bolts, reducing scrap rates during startup and long production runs.
The modern manufacturing landscape demands both fast lead times and cost efficiency. Operating our facility in Jiangsu allows BAOD EXTRUSION to leverage China's mature component supply chain while adhering to strict quality controls.
By using localized precision machining for core structural assemblies and sourcing electrical components globally (Siemens PLC, Schneider switchgear, Omron heat controllers), we deliver reliable performance at competitive price points. This integration ensures our customers benefit from high machine reliability alongside rapid parts availability.
Our supply chain model focuses on vertical integration: tooling design, CNC machining of extruder barrels, and custom assembly of line components are all executed in-house. This structure shortens engineering adjustment cycles, enabling us to deliver customized extrusion configurations within 60 to 90 days from order confirmation.
For international buyers and procurement departments, selecting the right extrusion equipment involves balancing performance requirements with direct financial return. Below is a comparative overview highlighting the positioning of BAOD EXTRUSION systems relative to other options on the market.
