Explore our primary collection of high-performance polymer extrusion systems designed for demanding industrial applications worldwide.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is a globally recognized manufacturer and designer of high-end plastic extrusion machinery. Leveraging more than 25 years of profound design experience originating from the tech-rich ecosystems of Taiwan through our parent group (KINGSWEL GROUP), we established our mainland manufacturing base in Shanghai in 1999, followed by major facility expansions in Jiangsu.
Our company specializes in solving high-precision engineering challenges, allowing automotive, medical, aerospace, and communication giants to realize tight dimension tolerances, complex multi-layer configurations, and efficient output capacities. We stand out in the global market by consistently maintaining our focus on quality control, structural longevity, and intelligent control interfaces.
Our long-term R&D efforts are strictly concentrated on the development of critical high-performance sectors:
Modern industrial tube extrusion demands high precision to support applications ranging from medical micro-catheters to high-pressure automotive fuel lines. Achieving sub-millimeter concentricity and linear consistency requires a deep understanding of polymer rheology, thermal profiling, and mechanical calibration.
At the core of BAOD's technological superiority is our custom screw geometry design. Each polymer type (e.g., FEP, PU, PA, PVC, HDPE) exhibits unique shear sensitivity and viscosity changes. Our engineering team designs screw profiles that prevent thermal degradation while ensuring homogeneous melt flow. Our high-precision single-screw extruders (SJ Series) feature L/D ratios tailored to specific materials, ensuring optimal compression, plasticization, and pressure stabilization before the melt enters the die head.
A precision extrusion line is a system where the performance of each stage depends on the consistency of the others. A breakdown at any point can compromise the entire line's output:
Utilizing high-torque AC servo drives paired with high-ratio gearboxes to ensure vibration-free screw rotations. Melt pumps are integrated for sensitive resins, absorbing pressure fluctuations from the screw to deliver a steady volume of melt to the die.
Stainless steel water troughs with multi-chamber vacuum calibrators control pressure dynamics down to millibar levels. This design manages cooling rates, preventing premature ovality and dimensional shrinkage.
Synchronized pulling systems with dual-belt contact tracks prevent tube compression or slippage. Our servo motors maintain exact linear pulling speeds, communicating directly with the main PLC.
For small-diameter tubes, traditional cutting can collapse the tube profile. Our rotary fly knife cutters (FQ Series) use high-torque motors to cut at speeds matching the linear flow, delivering burr-free cuts.
Automotive and medical OEM buyers look for more than just raw machinery. They seek suppliers capable of integration into automated factories. Procurement teams face challenges related to compliance, OEE (Overall Equipment Effectiveness), safety, and post-purchase service. Understanding these priorities helps structure successful purchases:
Our manufacturing base in Jiangsu, China offers a strong combination of technical competence and cost efficiency. This geographic location provides key operational advantages:
Producing single and multi-lumen micro-tubing in cleanroom environments. These systems work with medical-grade TPU, FEP, and PVC, maintaining wall thickness consistency to prevent tube collapse during medical procedures.
Manufacturing multi-layer PA (Nylon) and TPV hoses designed to transport corrosive fuels and cooling fluids. These lines feature co-extrusion technology to prevent fuel vapor leakage and meet automotive safety standards.
High-speed production lines for HDPE silicone-core microducts used in fiber optic networks. The co-extruded inner silicone layer reduces friction, allowing fiber cables to be blown over longer distances.
Expanding globally requires compliance with regional safety, emission, and electrical standards. BAOD EXTRUSION builds machinery in accordance with international safety requirements, ensuring smooth integration into local production sites:
All BAOD systems can be configured to comply with CE marking requirements, UL electric cabinet specifications, and local safety standards. Our testing protocols include factory acceptance tests (FAT) and detailed documentation for installation qualification (IQ) and operational qualification (OQ), which are critical for medical grade manufacturing.
We provide technical support through physical deployment of commissioning engineers and advanced remote diagnostic systems. Using remote connectivity, our design engineers can analyze PLC states, monitor extrusion pressure profiles, and resolve software issues, reducing unscheduled downtime.

We combine a high-precision melt pump with our SJ series extruders to eliminate flow fluctuations. This is supported by a high-frequency multi-axis laser micrometer and a closed-loop PLC system. When the micrometer detects variations, the PLC adjusts the haul-off puller speed or the screw RPM to maintain tolerances within ±0.01mm to ±0.02mm.
Fluoropolymers like FEP require high processing temperatures (up to 400°C) and corrosive protection, demanding specialized nickel-alloy (Hastelloy or Xaloy) barrels and screws. Nylon (PA) is highly hygroscopic and requires specialized drying hoppers and screws with dedicated compression ratios to handle its low melt viscosity and prevent hydrolytic degradation.
Adhesion is managed through precision die head design and temperature control at the co-extrusion crosshead. We design customized flow channels that ensure the layers meet under optimal heat and pressure. For incompatible polymers, we integrate specialized tie-layer extruders within the multi-layer setup.
Standard lines generally take 60 to 90 days. Complex configurations, such as multi-layer medical catheter lines or high-speed corrugated tube lines requiring custom crossheads, have a typical lead time of 120 to 150 days. This timeline includes design approval, machining, assembly, and factory acceptance testing (FAT).
We assemble electrical cabinets using UL-approved components (e.g., Siemens, ABB) and follow CE standards for the European market. Our machinery features dual-channel safety loops, emergency shut-offs, protective shielding, and meets CE machine safety directives.
We offer remote setup assistance as well as on-site engineering support. Our technicians assist with leveling, electrical hookups, die-head calibration, and initial trial runs. We also provide remote diagnostics to monitor system sensors and assist local maintenance teams.
