State-of-the-art co-extrusion technology designed for global polymer tubing manufacturing.
Polyamide (PA), commonly referred to as Nylon, serves as the cornerstone polymer for modern pneumatic and fluid control circuits globally. Known for its exceptional mechanical strength, heat stability, chemical resistance, and high burst pressure thresholds, PA pneumatic hoses are critical components across automotive chassis systems, factory automation, robotics, and medical devices.
Within the landscape of pneumatic hose production, precision is non-negotiable. Standard industrial setups demand hoses that can withstand continuous operational pressures of up to 2.0 MPa while maintaining structural flexibility and stress-crack resistance. To achieve these metrics, high-precision extrusion systems must control dimensions at a microscopic scale.
This whitepaper explores the critical engineering parameters of PA6, PA11, and PA12 extrusion technologies. We investigate the technological roadmap driving modern factories, analyze how Smart Factory 4.0 paradigms are reshaping manufacturing consistency in China, and provide global procurement teams with the baseline metrics needed to identify high-value machinery.
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 research and fabrication expertise, the company originates from the prestigious design standards of Taiwan, establishing its initial manufacturing base in Shanghai in 1999 under our parent company (KINGSWEL GROUP).
Through continuous investments in R&D, BAOD EXTRUSION has positioned itself as an industry leader in precision extrusion technology. Our focus remains steadfast on maximizing process automation, equipment safety protection, and processing efficiency for polymers like PA, TPV, PVC, and Fluoropolymers.
Exploring the engineering shifts and design changes driving next-generation PA tubing production.
Automotive and chemical sectors demand composite tubing with barrier layers. Our systems offer up to 5-layer co-extrusion technologies, combining Polyamide outer protective layers with EVOH or Fluoropolymer inner barrier linings. This decreases fuel permeability and dramatically improves the lifespan of critical transport lines.
Using ultrasonic wall thickness detection linked to gravimetric feeding units, BAOD machines achieve a concentricity profile exceeding 95%. Automated feedback loops instantaneously adjust screw speeds and puller traction, keeping dimensional variation below ±0.03mm, protecting against structural weak points under cyclic pressure.
By employing smart vacuum calibration tanks equipped with frequency-inverter water pumps, we reduce operational energy consumption by 35%. Dynamic spray cooling adjusts in real-time to the extrudate temperature, preventing thermal shock, residual stress, and micro-void formation in dense crystalline structures.
Modern polymer processing machinery must adapt to unstable supply chain dynamics. BAOD EXTRUSION coordinates a fully localized vertical manufacturing model. From structural frame processing, precision heat treatment of nitrided screws, to state-of-the-art PLC software coding, our entire chain is integrated internally.
Each machine frame undergoes comprehensive stress-relief processes to guarantee decades of structural alignment. Extrusion dies are machined with specialized mirror-polishing systems to minimize shear stress on hot PA melts, eliminating typical optical surface defects and ensuring smooth inner flow channels.
Providing specialized extrusion setups engineered for specific industrial sectors globally.
Engine bay conditions require high-temperature tolerance and mechanical resilience. Our PA11/PA12 lines output lightweight vacuum brake lines, diesel fuel delivery lines, and radiator cooling hoses compliant with SAE J844 and DIN 73378 standards.
Producing medical-grade PVC, PU, and PA catheter tubes requires strict cleanroom-compliant extrusion systems. Our precision melt pumps and custom micro-sizing vacuum systems ensure zero contamination and extreme dimensional stability at high linear production speeds.
Continuous movement in automated robotic cells induces severe bending stress. The PA tubing extruded on our lines features enhanced flexural fatigue life, helping prevent unexpected kinks and pressure drops in automated assembly plants.
When purchasing high-end capital machinery from China, global enterprises focus heavily on compliance, safety, and field service support. At BAOD EXTRUSION, we build our machines to align directly with international norms, integrating globally-sourced core control elements.
Whether your project requires conformity to CE Directives in Europe or UL/CSA Standards in North America, our electrical control cabinets and safety systems are customized to pass local verification easily.

PA11 and PA12 exhibit lower moisture absorption and superior dimensional stability compared to PA6. Extruding PA11/12 requires precise control over the screw shear rate and melt temperature profiles to prevent polymer degradation. Screw designs must incorporate barrier flights and mixing elements designed for lower processing temperatures and optimal melt homogenization.
The gravimetric dosing system measures the weight of raw material fed into the extruder. By cross-referencing this feed rate with the haul-off speed from the puller and dimensions measured by the online ultrasonic gauge, the PLC system makes real-time adjustments. This maintains consistent wall thickness and concentricity, preventing structural variance across the extruded tube length.
Small diameter tubing is prone to deformation upon exiting the extrusion die. The vacuum sizing tank uses a calibration sleeve to apply negative pressure, holding the outer diameter of the tube against the calibration sleeve while it cools. This secures the geometric profile and maintains tight tolerances before the plastic enters the water spray cooling phase.
