Premium performance single layer tube extrusion lines, calibration units, and automated downstream auxiliary equipment manufactured by BAOD Extrusion.
A global pioneer in manufacturing smart plastic extrusion machinery, delivering industrial-grade reliability since 2002.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was formally established in 2002, dedicating its core engineering competency to the design, manufacturing, and distribution of premium plastic extrusion equipment. Based on a legacy of 18 years of high-quality machinery fabrication in Taiwan, our original parent company, KINGSWEL GROUP, established our state-of-the-art manufacturing hub in Shanghai in 1999.
Today, our operational capabilities span a 25-year timeline of persistent innovation, culminating in our advanced facility in Jiangsu Province. We serve a diverse, international client base, supplying precision extrusion lines optimized for the automated processing of complex thermoplastic compounds.
Analyzing market dynamics, capacity trends, and the strategic positioning of Single Layer Tube Extrusion Lines in the modern era of manufacturing.
Across the automotive, medical, aerospace, and telecommunications sectors, the demand for single layer polymeric tubes has grown in complexity. While multi-layer tubes satisfy specific chemical barriers, single layer tubes represent over 60% of global tube consumption due to their cost efficiency, structural integrity, and simplified manufacturing profile. However, achieving precise physical dimensions—specifically maintaining concentricity and minimizing ovality—is highly demanding at high linear outputs.
Chinese manufacturers have transitioned from offering budget-focused equipment to delivering highly customized, precision-engineered solutions that rival European standards. This dynamic shift is driven by the integration of closed-loop servo motors, laser diameter measurement devices, and gravimetric dosing units. Jiangsu Baodie has pioneered these integrations, enabling global factories to process complex materials like Fluorinated Ethylene Propylene (FEP), Polyurethane (TPU), Polyamides (PA11/PA12), and Medical-grade PVC with repeatable accuracy.
Rigid requirement for medical-grade PVC and PU tubes with wall thicknesses under 0.2mm, demanding sterile, non-contaminating vacuum sizing and high-speed rotary cutting.
Focusing on heat-stabilized PA12 and PA6 single-layer lines. These tubes must handle high burst pressures, requiring consistent crystallization and orientation during cooling.
Production of HDPE microducts lined with internal silicone layers or ribs, optimized for blowing fiber-optic cables over long distances in communication grids.
Comprehensive engineering specifications guiding the next generation of plastic extrusion performance.
To produce quality tubing consistently, every stage of the extrusion line must be dynamically synchronized. This technical roadmap details the mechanical and automation benchmarks engineered by BAOD Extrusion to guarantee minimal dimensional deviations.
| Extrusion Line Stage | Technical Features | Automation & Quality Integration | Impact on Final Product |
|---|---|---|---|
| 1. Material Feeding & Extruder | Bimetallic screw & barrel; gravimetric batch dosing; precise PID heating elements. | Loss-in-weight control loop; synchronization with puller speed to maintain linear mass weight. | Homogeneous melt viscosity, elimination of pressure fluctuations, consistent molecular density. |
| 2. Die Head & Tooling | Spiral mandrel or spider die design; chrome-plated flow channels; custom tooling geometry. | Thermal distribution simulations optimized for specific polymer rheology. | Uniform wall thickness distribution; reduction of weld lines and internal stress concentrations. |
| 3. Vacuum Calibration & Cooling | Multi-chamber vacuum tank; closed-loop vacuum pressure control; water temperature regulation. | Modulating vacuum valve control system synchronized with dynamic laser outer-diameter gauge. | High precision circular geometry; ovality control down to < 0.05 mm; rapid crystallization. |
| 4. Haul-off (Puller Unit) | Dual belt puller (TKB) or crawler (TKC); high-torque servo motors; multi-groove backing plates. | Zero-slip pneumatic tensioning system; real-time line speed matching via EtherCAT protocol. | Uniform pulling force, prevention of tube deformation or surface scratching during high-speed run. |
| 5. Cutting & Coiling Systems | Rotary fly-knife cutter (FQ); servo winding displacement system; dual-shaft winder (SPS-Dh). | Optical detection for cut length verification; torque-controlled winder preventing tension spikes. | Clean, burr-free cuts; neatly tensioned coils suitable for automated high-volume packaging. |
The primary advantage of BAOD machinery is the integrated PLC closed-loop control system. By gathering real-time dimensional data downstream, the PLC makes micron-level adjustments to extruder motor speed and vacuum tank negative pressure. This setup corrects fluctuations caused by raw material variations, ambient temperature shifts, or electrical supply cycles, maintaining production tolerances within ±0.02mm to ±0.05mm depending on the resin type.
