Explore our premium extrusion lines, downstream haul-offs, and specialized medical tube manufacturing equipment.
Providing the foundations of polymer processing precision for over two decades.
Established in 2002 under the corporate brand BAOD EXTRUSION, Jiangsu Baodie Automation Equipment Co., Ltd. has stood as a pioneer in plastic extrusion machinery. Our roots date back to 1999 when our original parent company, KINGSWEL GROUP, brought 18 years of high-end design and manufacturing experience from Taiwan to set up a world-class manufacturing base in Shanghai.
Over the past 25 years, our engineering departments have maintained an unyielding focus on high-efficiency output, extreme dimensional tolerances, and high-automation integration. We offer comprehensive solutions that range from primary bimetallic extrusion screws to state-of-the-art multi-lumen medical catheter lines, ensuring global processors achieve optimal melt quality and maximum throughput.
Ultra-tight tolerances on polymer melt flow control.
Optimized screw geometry to reduce energy usage.
In-depth look at extrusion screw physics, material coatings, and dynamic shear control.
To counteract intense mechanical friction and corrosive outgassing, we utilize base alloys such as 38CrMoAlA, supplemented with PTA (Plasma Transferred Arc) welding of nickel- or cobalt-based tungsten carbide alloys on flight tips. This creates a surface hardness of 60–65 HRC.
Utilizing variable pitch and depth designs alongside barrier flights, our screws separate the solid polymer bed from the melted pool. This minimizes unmelts, lowers melt temperatures, and increases volumetric efficiency.
Through precision-designed Maddock and Pineapple mixing sections, we ensure that color concentrates, additives, and fillers are homogenized under low shear, preventing thermal degradation.
In high-precision extrusion systems, melt pressure stability is critical. Conventional screws often fail when processing materials like Fluoropolymers or highly loaded TPU, leading to surges. Our proprietary Micro-Grooved Feed Zone coupled with Decompression-Zone Screws balances internal pressures. The results are clear: melt pressure fluctuations are reduced to less than ±0.3 bar, ensuring uniform wall thickness on highly sensitive downstream extrusions.
Leveraging Chinese industrial clusters to deliver high-performance, cost-effective solutions.
Located in the industrial heartland of Jiangsu and Shanghai, BAOD EXTRUSION accesses a mature ecosystem of raw steel suppliers, nitriding specialists, and component manufacturers. This proximity minimizes raw material lead times and transportation overheads.
Our factory features 4-axis and 5-axis CNC screw grinding machines, heavy-duty deep-hole boring machines, and vacuum nitriding furnaces. By controlling the entire manufacturing process in-house, we eliminate external quality deviations.
Backed by a team of over 100 dedicated technical operators and engineers, our team brings decades of combined expertise in polymer physics, mechanical engineering, and automated PLC programming to every system we build.
Engineered to meet the requirements of international medical, automotive, and optical industries.
Medical applications require strict compliance with FDA food-contact standards and Class 10,000 cleanroom operational requirements. Our medical-grade screw geometries prevent material degradation in sensitive polymers like TPU, Pebax, and FEP. They provide stable melt flows for multi-lumen micro-catheters used in invasive cardiovascular surgeries.
Automotive manufacturers require multi-layer co-extrusion technology for low-permeation fuel lines and weatherstripping. We construct complex multi-layer PA (Nylon) smooth and corrugated tube lines, as well as TPV composite hose systems with integrated polyester knitting, meeting automotive standards for heat, chemical, and pressure resistance.
The deployment of fiber-optic networks requires HDPE silicon-core microducts. This requires co-extrusion lines capable of outputting a dual-layer profile with a low-friction internal lining. Our systems are engineered to run at high speeds while maintaining precise diameters and concentricity.
Extruding PC, PMMA, or PS lampshades demands optical-grade surface finishes. Any variation in melt temperature can lead to internal stresses, visible flow lines, or optical distortions. Our high-homogeneity extrusion screws ensure uniform optical refraction and high dimensional stability.
The road to smart extrusion, high output, and green materials.
Modern manufacturing requires remote telemetry, predictive maintenance, and real-time process control. Our machines integrate advanced PLC interfaces, closed-loop gravimetric dosing feedback, and online ultrasonic wall thickness measuring tools. This automatically matches line speeds with screw RPM, keeping product tolerances within micro-meters.
With the rise of bio-plastics (like PLA, PHA) and post-consumer recycled polymers (PCR), extrusion systems face challenges like unpredictable moisture absorption and inconsistent melt viscosities. We design screws specifically with active venting zones (degassing systems) and customized compression zones to process these materials without thermal breakdown.
We build machinery to meet the safety and quality requirements of global industrial standards.
All structural frameworks, electrical cabinets, and safety interlocks are manufactured to meet CE standards, ensuring compliance for European and North American installations.
Our ISO 9001:2015-certified facilities monitor every phase of production, from raw steel spectroscopic analysis to final line testing before shipment.
By integrating secure cloud-gateway modules into our control panels, our field engineers can remotely diagnose PLC programs and optimize melt parameters from our headquarters.
