Founded in 2002, Jiangsu Baodie Automation Equipment Co., Ltd. (BAOD EXTRUSION) stands as a prominent pioneer in the development, engineering, and execution of high-efficiency plastic extrusion lines. Built on a rich foundation of over 25 years of engineering experience, our origins trace back to the KINGSWEL GROUP in Taiwan, which initially established a dedicated production footprint in Shanghai in 1999 to support the rapidly growing global demand for advanced polymer processing technologies.
Operating today from our modern, state-of-the-art 16,000 square meter manufacturing base, BAOD EXTRUSION coordinates a team of over 100 dedicated technical engineers, design specialists, and global service experts. By bridging Taiwan’s highly refined mechanical methodologies with domestic manufacturing agility, we provide end-to-end custom extrusion line services designed to fulfill demanding processing tolerances, maximize resin utilization, and maintain optimal uptime.
Polyethylene (PE) profiles—spanning High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Ultra-High-Molecular-Weight Polyethylene (UHMW-PE)—pose distinct challenges in profile processing due to their specific viscoelastic properties, melt elasticity, and thermal contraction characteristics.
Utilizing high L/D ratios (ranging from 28:1 to 33:1) and specialized barrier screw configurations, our extruders guarantee uniform melt temperatures, optimal plastification, and consistent head pressure, minimizing output variance.
We leverage advanced finite element analysis (FEA) to profile melt velocity distribution inside the die. This mitigates internal stresses, minimizes die swell, and maintains clean corner definitions on complex custom shapes.
Incorporating water-ring vacuum pumps alongside multi-axis adjustment platforms, our calibration tables ensure fast heat transfer, preventing the deformation of complex structures during cooling.
Information Gain: Engineering Insight on PE Viscoelasticity — Because PE displays pronounced shear-thinning and high shrink rates (up to 1.5% to 3% depending on crystallinity), our tooling adjustments incorporate localized shrinkage compensation zones. This design ensures that the extruded profiles cool into the precise specified dimensions without warpage or sink marks.

As the plastic extrusion industry transitions toward digital integration, the technological development path of BAOD EXTRUSION focuses on three main areas: predictive maintenance, automated material savings, and circular economy compatibility. Our roadmap details the implementation of technologies that improve efficiency and reduce environmental impact:
Edge Computing & Self-Optimizing Loops: Future iterations of our PE profile lines will feature integrated laser-scanning gauges connected via OPC UA protocols. The real-time dimensions of the PE profiles are processed directly at the machine edge. If a deviation is detected, the PLC automatically regulates the puller speed or melt pump throughput to correct tolerances without operator intervention.
Adaptive Screw Geometry for Recycled Feedstocks: With regulatory frameworks pushing for higher percentages of Post-Consumer Recycled (PCR) content, our screw geometry research focuses on high-venting systems. These configurations manage the volatile organic compounds (VOCs) and moisture variations found in recycled PE flakes.
A PE profile extrusion line is not merely a combination of components; it is an integrated processing system designed to resolve specific commercial and technical challenges across global industries.
Processing solutions for underground HDPE protective conduits, fiber optic micro-ducts, and structural spacer components. Equipment is optimized for high environmental stress crack resistance (ESCR).
Integrated manufacturing lines for complex multi-layer or co-extruded TPE, TPV, and PE automotive sealing elements, maintaining high precision for assembly tolerances.
Cleanroom-compatible setups designed for processing medical-grade LDPE, TPU, and PVC. Features non-contaminating vacuum configurations and multi-lumen capability.
Manufacturing at BAOD EXTRUSION’s Jiangsu facility demonstrates how China's modern manufacturing infrastructure translates directly into value for international clients. The integration of advanced machining systems and localized supplier networks allows us to produce high-specification extrusion lines with shortened lead times.
Rather than relying on outsourced components, we execute key fabrication steps—such as CNC machining of screw flights, barrel nitriding, and complex die wire-cutting—directly within our facility. This vertical integration allows for rigorous quality control at every stage of production.
Our strategic location in the Yangtze River Delta engineering cluster provides access to high-grade steel mills and precision electronic suppliers. This cluster allows BAOD EXTRUSION to source components like Siemens motors, Omron thermal control units, and ABB frequency converters efficiently. Consequently, we deliver systems that match European technical performance while optimizing initial capital expenditure.
Full European safety and machinery directive compliance verified via third-party testing.
Panel design and electrical layouts tailored to meet North American safety codes.
Strict adherence to standardized quality management pathways for every system built.
Integrating manufacturing equipment into overseas production environments requires compliance with local safety regulations and operational standards. At BAOD EXTRUSION, we configure our machinery to meet the regulatory requirements of your target market.
Our engineering teams adapt electrical cabinets to comply with local codes (such as NFPA 79 for North America or EN 60204-1 for European countries). Safety interlocks, dual-channel emergency stop circuits, and heavy-duty mechanical guarding are integrated directly during the assembly phase.
Remote Diagnostics & On-Site Commissioning: Every PE profile extrusion line is equipped with a secure VPN router interface. This allows our design team to perform remote PLC updates, monitor signal inputs, and diagnose process anomalies, reducing the need for on-site service visits. For physical commissioning, BAOD provides field service technicians to manage installation, calibrate mechanical interfaces, and conduct operator training.
BAOD EXTRUSION presented its latest "Smart Extrusion & High-Efficiency Innovation" solutions at Booth 7.1C04, showcasing real-time automated controls.
We deliver specialized production systems for explosive-conveying micro-tubes, designed to meet rigorous safety and dimensional standards.
