Explore our premium grade extrusion lines designed for high-performance and manufacturing excellence.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, is dedicated to the design, manufacturing, and sales of high-end plastic extrusion equipment. Leveraging over 25 years of engineering experience in designing and fabricating high-quality machinery, our foundations are deeply rooted in precision manufacturing. Our original parent company (KINGSWEL GROUP) invested in establishing our primary extrusion machinery manufacturing base in Shanghai in 1999, paving the way for decades of technological leadership in the polymer processing market.
Today, our company stands as a benchmark for automated, highly efficient, and safe plastic extrusion lines, serving a global client base in sectors ranging from automotive and medical tubing to aerospace and infrastructural pipe systems.
Polyethylene (PE), including its variations HDPE, MDPE, and LDPE, is the cornerstone of modern industrial fluid piping, microduct systems, medical conduits, and structural sheeting. Achieving stable, high-throughput extrusion of PE requires a comprehensive understanding of the polymer's thermal properties, shear sensitivity, and melt behavior. As a leading custom PE plastic extruder machine manufacturer, BAOD Extrusion integrates advanced rheological designs, thermodynamic control, and precise downstream calibration to achieve superior product consistency and wall thickness uniformity.
The core of any PE extruder lies in its screw and barrel design. Conventional screws often fail to homogenize high-molecular-weight PE without generating excessive shear heat, which leads to polymer degradation. BAOD utilizes custom-engineered barrier screws with an optimized Length-to-Diameter (L/D) ratio typically ranging from 30:1 to 38:1.
This design splits the polymer path into solid and melt channels, ensuring that only fully melted polymer passes into the metering zone. Additionally, distributive and dispersive mixing elements (such as Maddock mixers and pineapple mixing sections) are integrated to ensure uniform color masterbatch distribution and stable melt temperature profile before the polymer enters the extrusion die head.
PE extrusion requires precise thermal management to maintain the polymer melt strength while preventing degradation. Our extrusion lines feature multi-zone barrel heating systems using cast aluminum heaters paired with high-efficiency cooling fans. The control architecture utilizes PID (Proportional-Integral-Derivative) algorithms integrated into Siemens S7-1500 PLC systems, maintaining temperature fluctuations within ±1°C.
In addition, our die heads incorporate internal spiral mandrel technology. This layout distributes the melt flow symmetrically, eliminating weld lines (knit lines) and minimizing orientation stress. The result is a finished PE pipe or tube with uniform circumferential strength and isotropic burst pressure capabilities.
Post-die calibration is critical for establishing the exact outer diameter and roundness of PE pipes and microducts. BAOD’s patented auto-vacuum sizing tanks utilize closed-loop pressure control. By continuously monitoring the vacuum level and adapting the water spray intensity, our systems prevent deformation, especially in thin-walled microducts and multi-lumen tubes.
The sizing sleeves are manufactured from wear-resistant bronze alloys with specialized water lubrication rings, minimizing friction and preventing surface score marks on the extruded PE profile. High-precision pullers with servo-driven caterpillar tracks ensure tension-free, slip-free pulling forces synced directly with the extruder screw output speed.
Combining the cost advantages of Chinese advanced manufacturing with strict global compliance and on-site localization services.
Situated in the heart of Jiangsu’s advanced machinery manufacturing corridor, BAOD Extrusion benefits from deep, optimized local supply chains. We procure high-precision components, specialized tool steel, and structural fabrications locally, reducing lead times and passing substantial capital savings to our global clients.
All machinery engineered by BAOD is compliant with European CE safety regulations, ISO 9001:2015 quality standards, and UL certification requirements for electrical panels. Our control cabinets are constructed using flame-retardant materials, safety interlocks, and emergency stop features that guarantee worker safety in any environment.
Global procurement teams demand equipment that maximizes Overall Equipment Effectiveness (OEE) while minimizing Total Cost of Ownership (TCO). BAOD resolves this dynamic through smart energy-saving motors, simplified maintenance configurations, and standard off-the-shelf electronic parts that can be sourced in local markets globally.
We bridge the geographical gap through a network of local partners and field service engineers. From factory floor planning and layout consulting to commissioning, calibration, and operator training, we ensure your production crew is fully equipped to run the extrusion line efficiently from day one.
Adapting to the future of smart infrastructure, eco-friendly polymers, and high-precision automation.
The integration of IoT and cloud diagnostics is reshaping extrusion plants. BAOD’s modern PE extrusion lines feature OPC-UA communication protocols. This allows managers to monitor screw torque, melt pressures, raw material consumption, and thermal zones remotely in real-time, integrating with factory ERP systems for optimized operations.
With regulations driving the use of Post-Consumer Recycled (PCR) plastics, manufacturers must run feedstocks with variable melt flow indexes (MFI). Our custom-designed degassing extruders and dynamic filtering systems allow processors to run up to 100% recycled PE flakes while preserving pipe integrity and smooth surface finish.
In North America and Europe, fiber-to-the-home (FTTH) expansion has triggered massive demand for HDPE silicone core microducts. BAOD’s multi-layer co-extrusion technology enables simultaneous extrusion of the robust HDPE outer shell and the ultra-low friction co-efficient silicone inner layer, facilitating long-distance fiber blowing.

Expert answers to common engineering, customization, and procurement queries regarding PE Extruder Machines.
For most Polyethylene (PE/HDPE/LDPE) extrusion configurations, we recommend an L/D ratio of 30:1 to 38:1. This length ensures sufficient residence time for proper melting, degasification, and homogenization of the polymer chains under controlled shear rates, preventing thermal degradation while maximizing output capacity.
We utilize advanced spiral distributor co-extrusion die heads coupled with gravimetric dosing systems. This system dynamically measures the weight of the feed material and adjusts the extruder screw and puller speed relative to each other, ensuring that each layer (such as the inner silicone layer of a microduct) stays within a minimal tolerance of ±0.03mm.
Yes, our custom PE extruder screws can be customized with venting zones (degassing sections) and continuous double-column hydraulic screen changers. This allows processing of recycled PE flakes or PCR material without interrupting production, efficiently discharging volatile gases and filtering out contaminants.
