Explore our premium industrial plastic tubing extrusion lines engineered for high output, precise dimensional tolerances, and automated processing.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, dedicated to designing, manufacturing and sales of plastic extrusion equipment. Based on 18 years experience of designing and fabricating high quality machines in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing extrusion machines manufacturing base in Shanghai in 1999.
25 years experience of plastic extrusion designing and manufacturing. Long-term focus on research and development for:
Custom-engineered extrusion architectures built to fulfill rigorous operational benchmarks across primary international sectors.
Modern vehicles demand absolute durability for fuel lines, vacuum lines, and sealing profiles. BAOD Extrusion lines produce multi-layer PA (Nylon) smooth and corrugated tubes, as well as TPV/PVC sealing strips. These systems handle high extrusion pressures and maintain dimensional tolerance within ±0.03mm, ensuring resistance to chemical corrosion, high temperatures, and structural degradation under extreme dynamic stresses.
Medical tube manufacturing mandates strict compliance with FDA standards and Class 10,000 cleanroom environments. Our PVC, TPU, and multi-lumen micro-extrusion lines are engineered for precise medical catheters. Using advanced closed-loop outer diameter (OD) and wall thickness feedback systems, we guarantee high repeatability and zero contamination, allowing safe deployment in life-critical medical devices.
As 5G networks expand worldwide, demand for HDPE silicone-core microducts has surged. Our co-extrusion technology enables the concurrent processing of an outer wear-resistant HDPE layer and a low-friction internal silicone core. This structural combination minimizes friction during cable blowing, enabling longer, faster, and safer fiber-optic cable deployment over vast continental networks.
For industrial fluid processing, petrochemical transport, and utility networks, we supply heavy-duty lines like metal pipe coating and UHMWPE profiles. These lines protect steel pipes with high-density polyolefin shells, providing mechanical resilience and corrosion defense in challenging subterranean and offshore environments.
Integrating mechanical precision with digital intelligence to shape the next generation of plastic extrusion systems.
Our lines integrate high-frequency laser micrometers and ultrasonic wall-thickness monitors at the sizing and cooling stages. By continuously scanning the tube's outer diameter and wall thickness at 360 degrees, data is fed back to the Siemens PLC. The controller automatically adjusts the vacuum level in the calibration tank and the haul-off puller speed. This active closed-loop feedback keeps outer diameter variations within ±0.02mm, even at high line speeds.
Processing temperature-sensitive polymers (like TPV, PVC, and TPU) requires precise shear control to prevent material degradation. BAOD's custom screw designs utilize barrier flights and dispersive mixing elements. This enables thorough melt homogenization at lower thermal thresholds. Operating at lower temperatures preserves the polymer's molecular weight, improves mechanical properties, and reduces energy consumption by up to 22% compared to standard screw designs.
To produce multi-functional tubes (such as low-permeability fuel lines with EVOH barriers or low-friction microducts), our proprietary spiral mandrel die heads ensure uniform distribution across all layers. The flow channels are designed using advanced finite element analysis (FEA) to eliminate stagnation zones, maintain balanced pressure drops, and prevent inter-layer delamination during cooling.
Modern sustainability requirements demand that extruders handle post-consumer recycled (PCR) resins without losing product quality. Our upcoming extrusion platforms feature degassing barrels and melt filtration systems. This design accommodates raw material inconsistencies, enabling the processing of up to 50% recycled feedstocks while maintaining product specifications.

Processes reinforced high-pressure hoses with integrated knitting meshes. Offers durability and flexibility for automotive and industrial fluid lines.
Handles challenging profiles and weatherstrip lines. Integrates online punching, coating, and cutting tools to streamline post-extrusion processing.
Facilitating seamless deployment, regulatory alignment, and long-term operational success for international manufacturers.
Procuring machinery globally requires managing compliance, language barriers, and post-installation support. BAOD Extrusion addresses these challenges with structured programs that simplify international procurement and commissioning.
Regulatory Alignment & Certifications: All of our extrusion machinery, cooling tanks, and puller modules comply with CE safety standards. The electrical architecture features premium components from brands like Siemens, Omron, and Schneider, configured to meet regional safety and electrical standards (including UL and CSA codes for North America).
Factory Acceptance Testing (FAT) & Quality Assurance: Before shipping, each line undergoes comprehensive FAT testing using our customer's exact raw material formulations. We verify dimensional stability, line speed, and power consumption, providing detailed testing video logs and data profiles to speed up onsite installation.
Remote Diagnostics & Field Support: Our control cabinets feature IoT remote connectivity. If a parameter drift or PLC fault occurs, our engineers can access the machine remotely, diagnose the issue, and push software adjustments. For physical maintenance, our localized field partners and quick-ship spare parts logistics minimize unplanned downtime.

Get answers to common engineering questions regarding plastic tubing extrusion systems, material handling, and optimization.
We achieve dimensional stability through a closed-loop PLC system. High-precision laser micrometers continuously measure the tube's outer diameter post-vacuum calibration. If deviation occurs, the PLC automatically adjusts the haul-off puller speed and the vacuum tank pressure. Additionally, our gravimetric dosing systems regulate raw material feed rates to maintain melt density and weight-per-meter specifications.
We design our screws with a customized length-to-diameter (L/D) ratio, typically ranging from 28:1 to 33:1, depending on the polymer. The screw flight geometry includes barrier sections and Maddock mixing heads. This design applies low shear stress to the polymer while providing uniform heat distribution, preventing localized overheating and degradation in heat-sensitive compounds.
Proper adhesion requires matching the flow velocities and melt temperatures of each polymer layer within the die head. We design our multi-layer spiral distributor die heads using flow simulation software. This ensures that the pressure and flow rates of each layer align at the merge point, creating a strong bond without structural defects.
Our barrels and screws are made from high-grade 38CrMoAlA alloy steel, nitrided and polished to resist wear. For abrasive polymers (such as filled compounds or UHMWPE), we offer bimetallic barrels lined with tungsten carbide alloys. Under normal operating conditions, these components offer an operational lifespan exceeding 15,000 working hours.
For thin-walled medical tubes, we use multi-stage vacuum calibration tanks equipped with high-pressure spray manifolds. An automatic water level and temperature control system prevents deformation as the hot melt enters the water bath, stabilizing the tube shape quickly to maintain tight tolerances.
Yes. Our Siemens PLC systems support standard communication protocols, including OPC UA, Profinet, and Modbus TCP. This enables integration into factory SCADA platforms, MES systems, and IoT databases, allowing operations managers to track output, energy consumption, and performance in real time.
