Explore our premium grade extrusion lines designed for high speed, absolute precision, and energy efficiency across medical, automotive, and industrial domains.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), established in 2002, is an industry-leading pioneer dedicated to the design, manufacture, and global distribution of high-end plastic extrusion machinery. Leveraging 18 years of experience in fabricating precision extrusion hardware in Taiwan under our original parent company, KINGSWEL GROUP, we established our world-class Shanghai production center in 1999, followed by major expansions in Jiangsu.
For a quarter of a century, BAOD has remained at the vanguard of innovation, specializing in high-performance polymer extrusion technologies. Our engineering matrix centers on micro-control systems, multi-layer co-extrusion crossheads, high-speed corrugated pipe shaping mechanisms, and fully automated downstream processing units.
Our core development strategy focuses on mitigating material degradation while maximizing polymer melt homogeneity. Through advanced computational fluid dynamics (CFD) and proprietary screw configuration design, we address the unique challenge of Polypropylene (PP) extrusion processing.
Precision Mechanical Tolerance
We achieve dimensional tolerances as narrow as ±0.03mm, matching stringent European medical and automotive component standards.
Turnkey System Integration
Complete design-to-execution support, including raw material feeding systems, vacuum calibration, caterpillar hauling, cutting, and automated dual-spool coiling.
Analyzing how custom PP profiles, microducts, and multi-lumen tubing address global manufacturing, infrastructure, and engineering demands.
Polypropylene (PP) offers structural stability combined with a low density of ~0.90 g/cm³. Custom PP extrusions replace heavier metal or elastomeric components in automotive fluid routing, air ducts, and aerodynamic seals, enhancing overall fuel economy and EV range.
Custom HDPE and PP silicone-core microduct extrusion lines facilitate the deployment of underground optical fiber networks. With a co-extruded low-friction inner silicone layer, these microducts reduce friction coefficient, allowing for long-distance pneumatic fiber blowing.
BAOD's precision tube extrusion lines produce medical-grade PP tubing characterized by chemical inertness, high temperature sterilization capability, and excellent resistance to kinking. Essential for drug delivery systems and sterile fluid transfer lines.
The demand for custom PP extruded components is growing, driven by circular economy mandates, lightweight vehicle construction, and the rapid expansion of fiber-to-the-home (FTTH) networks. Unlike PVC, Polypropylene releases no halogenated toxins upon incineration, positioning it as an environmentally preferred material for modern infrastructure.
Geographically, regions such as Europe and North America demand high-compliance, smart machinery that integrates with plant-wide SCADA systems. Industrial dynamics in Asia-Pacific emphasize high-speed output and multi-cavity co-extrusion setups to optimize cost-per-meter efficiency. BAOD Extrusion addresses this global market split by supplying extrusion lines that feature Siemens PLC controls, closed-loop pressure and melt monitors, and comprehensive digital integration capability.
Strategic technology milestones detailing BAOD's commitment to automation, precision control, and next-generation polymer processing.
Optimizing custom screw L/D ratios up to 33:1 to process high-molecular-weight PP with minimal thermal degradation.
Integrating auto-adjusting vacuum water tanks to regulate cooling temperatures based on inline dimensional feedback.
Refining flow channels to support up to 5-layer co-extrusion for composite PA/PP barrier tubes.
Deploying sensor suites to monitor extruder torque, die pressure, and motor temperature for preventative maintenance.
From cleanroom medical tubing to automotive assembly floors, see how BAOD extrusion lines adapt to specific operating environments.
Automated co-extrusion of TPV, PVC, and PP automotive weatherstrip seals. Inline metal inserts can be integrated using specialized crossheads, followed by punch operations and flocking applications.
High-speed manufacturing of HDPE/PP silicone core ducts. Lines are configured with multi-station winding equipment to produce continuous duct spools measuring up to 2,000 meters in length.
PP single-wall corrugated pipe lines designed to produce flexible electrical wire protection conduits. Running at speeds up to 30 m/min, with precise control over corrugation pitch.
Our machinery configurations adhere to CE directives and ISO 9001:2015 quality standards. We address regulatory issues like mechanical safety (EN ISO 12100) and electrical compliance (EN 60204) directly during the design phase. BAOD assists global manufacturers in meeting FDA, EU 10/2011, and RoHS criteria for their end-products by engineering contact parts with inert, food-grade materials and corrosion-resistant alloys.
Understanding that downtime impacts profitability, BAOD provides localized support, including commissioning assistance, remote digital diagnostics, and scheduled maintenance. Our spare parts network keeps high-wear items like screw barrels, heaters, calibration sleeves, and cutter blades stocked for rapid deployment.

For PP extrusion, we recommend a screw L/D (Length-to-Diameter) ratio between 30:1 and 33:1. This length ensures sufficient residence time to achieve polymer melt uniformity without inducing thermal degradation. Additionally, we integrate barrier flights and mixing elements to enhance dispersion and temperature homogeneity before the melt enters the die.
Polypropylene has a high semi-crystalline shrinkage rate (typically 1.5% to 2.5%). We mitigate this by utilizing our custom-engineered Precision Auto Vacuum Sizing Tanks. These tanks feature multi-stage vacuum zoning and precise water temperature control (using heat exchangers), enabling structured, uniform solidification that maintains target profile geometries and dimensional stability.
Yes, we design and build multi-layer co-extrusion configurations (such as 3-layer or 5-layer setups). These lines feed different materials—like PP, PA, and adhesive tie layers—into a co-extrusion crosshead to manufacture automotive fuel lines, barrier piping, and chemical-resistant conduits.
With our high-precision tube extrusion systems, we achieve outer diameter (OD) and wall thickness (WT) tolerances of ±0.03mm to ±0.05mm. This accuracy is supported by closed-loop laser diameter gauges and ultrasonic thickness scanners linked to the primary PLC, which automatically adjusts the puller speed and vacuum pressure.
Depending on the model, screw diameter, and material viscosity, our SJ Series Single Screw Extruders offer output capacities ranging from 10 kg/h to 500 kg/h. For instance, our larger lines process PP at high output rates while keeping energy consumption low per kilogram of extruded product.
