Exploring structural configurations, material processing tolerances, and advanced thermal management tubing for modern automotive platforms.
The global automotive industry is undergoing a structural transition. The transition from Internal Combustion Engines (ICE) to Hybrid Electric Vehicles (HEV) and Battery Electric Vehicles (BEV) has completely rewritten the parameters for fluid management. Traditional heavy metallic fluid lines are being rapidly replaced by high-performance multi-layer polymer tubes. These components must withstand higher thermal stress, aggressive chemical coolants, and intense vibration while retaining ultra-low permeability.
At the center of this revolution is the Custom Automobile Tube Extrusion Line. Manufacturing tubes for fuel delivery, air brakes, battery pack thermal loops, and oil-cooler lines requires precision control. Polyamides like PA11 and PA12, thermoplastic vulcanizates (TPV), and thermoplastic polyurethane (TPU) present complex thermodynamic behaviors. Processing these materials requires deep expertise in extrusion screw architecture, vacuum calibration, and continuous closed-loop control.
Modern automotive standards demand multi-layer structures (typically 3, 5, or even 7 layers) to achieve the necessary combination of barrier properties, mechanical strength, and chemical resistance. A typical EV battery cooling tube, for example, may consist of a high-performance polyamide outer layer for gravel-guard resistance, a bonding tie-layer, and a chemical barrier core. Our advanced extrusion systems employ co-extrusion feedblocks and precision dies engineered to ensure uniform wall-thickness distribution across all layers.
Our feedblock designs utilize flow channel simulation tools to optimize melt flow rates. By eliminating dead spots and minimizing shear stress, we prevent material degradation during processing. This configuration ensures that each polymer layer maintains its mechanical and chemical integrity, yielding components with consistent burst pressures and high resistance to stress cracking.
To meet IATF 16949 requirements, automotive tube extrusion lines must maintain strict dimension control. A variation of even 0.05 mm in outer diameter or wall thickness can result in failure at quick-connect points. Our extrusion lines integrate continuous gravimetric dosing systems with multi-axis laser diameter gauges and ultrasonic wall thickness measurement devices.
The ultrasonic gauge constantly measures the inner and outer diameters, concentricity, and individual layer thickness. This data feeds back to the extruder's PLC, automatically adjusting the haul-off speed or extruder screw RPM in real-time. This process guarantees that every meter of extruded tube meets the tightest dimensional tolerances, significantly reducing scrap rates and maximizing production efficiency.
Jiangsu Baodie Automation Equipment Co., Ltd. (BAOD EXTRUSION) delivers a unique manufacturing proposition. Grounded in Taiwan design philosophies and refined since our parent group's establishment in Shanghai in 1999, we combine European-grade precision standards with Mainland China's manufacturing scale.
By positioning our 16,000 square meter factory in Jiangsu, we leverage a highly localized supply chain for premium components, machining, and engineering talent. Our facilities are equipped with CNC machining centers that construct high-durability barrels and screws. This layout allows us to offer customized co-extrusion machinery at optimized capital expenditures, without compromising on performance, line speed, or safety.
Our localized R&D team specializes in tailoring line layouts, vacuum systems, and die geometry to the unique physical characteristics of advanced engineering polymers. This ensures seamless line start-up and minimized commissioning cycles for our global automotive clients.

Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is dedicated to the design, manufacturing, and global sales of plastic extrusion systems. Backed by 18 years of design experience in high-quality Taiwanese machinery, the parent company (KINGSWEL GROUP) established the manufacturing base in Shanghai in 1999, followed by expanded operations in Jiangsu.
We possess over 25 years of design and manufacturing experience in precision extrusion technology. Our focus areas include:
Deploying customized extrusion infrastructure to support critical fluid delivery configurations in automotive assemblies.
Electric vehicle batteries require complex liquid cooling circuits. Our multi-layer polyamide and lightweight polypropylene extrusion configurations deliver high-precision tubing that prevents coolant permeation and simplifies assembly routing.
Designed for low permeation under aggressive conditions. Co-extruded fluoropolymer (PVDF) barrier layers are integrated to ensure compliance with global environmental and emissions standards.
High-strength Polyamide 12 lines must maintain dimensional stability under pressures exceeding 20 bar. Our extrusion systems feature high-stability cooling tables and pullers that ensure concentric wall thickness for safe connector integration.
Detailed answers to mechanical, metallurgical, and control challenges in modern plastic profile and tube extrusion lines.
We integrate multi-axis ultrasonic wall thickness measurement and laser diameter scanners directly downstream of the vacuum calibration tank. These scanners feed real-time dimensional data back to our central PLC system. Using closed-loop control algorithms, the system automatically regulates melt flow and line pull speeds to maintain a concentricity of ≥95% and keep outer diameter variations below ±0.05 mm.
Polyamides and TPVs exhibit high melt elasticity, requiring controlled cooling rates to prevent structural collapse or internal stress. Our dynamic vacuum calibration systems feature dual-chamber vacuum pumps and digital control valves. This allows operator adjustments to water levels and vacuum pressure in real-time, preventing ovality and surface flaws on the extruded tubing.
Fluoropolymers release trace acidic gases at processing temperatures. To ensure long service life, the extruder barrel, screw, feedblock, and die-head are made of highly corrosion-resistant alloys (such as Hastelloy C or Xaloy). This material choice prevents pitting and chemical degradation, maintaining reliable melt quality over long production runs.
Our single-wall corrugators can run at speeds up to 30 meters per minute for small-diameter PA/PE/PP tubing, depending on the material formulation. The machine utilizes a closed-loop water cooling system in the forming mold block chain, ensuring rapid cooling and precise forming at high production rates.
All BAOD lines are built on standard Siemens, Omron, or B&R automation platforms supporting OPC UA and Profinet protocols. This configuration allows direct communication with plant MES and ERP networks, enabling live monitoring of energy usage, scrap rates, runtime, and diagnostic alarms.
We offer comprehensive pre-shipment FAT (Factory Acceptance Testing) at our Jiangsu facility using customer-supplied raw materials. After delivery, our engineers assist with installation, calibrate control systems, and train local staff to ensure smooth integration and optimized throughput.
