BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to the design, manufacturing, and distribution of state-of-the-art plastic extrusion machinery. Based on 18 years of pioneering engineering in high-end plastic processing lines in Taiwan, our original parent company (KINGSWEL GROUP) established our specialized manufacturing base in Shanghai in 1999.

The global demand for specialized plastic extrusions continues to soar across key sectors including automotive, aerospace, healthcare, infrastructure, and electronic packaging. Modern manufacturing mandates extrusion hardware capable of working with increasingly complex polymers (such as TPV, UHMWPE, fluoropolymers, and multi-layer polyamide composites) while keeping dimensional variance within micrometer thresholds.
In the global market, processors are transitioning from simple mono-layer extrusions to high-precision, multi-lumen, and co-extruded solutions. These intricate requirements have shifted the focus toward highly specialized downstream units of extrusion lines. These auxiliary units, such as precision pullers, rotary fly knife cutters, and closed-loop vacuum calibration cooling tables, are no longer secondary concerns. Instead, they represent the defining parameters of yield optimization, wall thickness stability, and final product quality.
A high-output extrusion system operates as a chain of highly interlocked machinery. The performance of each individual unit directly dictates the dimensional precision and mechanical integrity of the final extruded product.
Acting as the core melt-delivery system, the SJ Series utilizes optimized L/D ratios (ranging from 25:1 to 38:1) tailored to polymer-specific rheology. Precision temperature control loops (±1°C accuracy) ensure uniform melt temperature, preventing localized shear degradation and ensuring consistent melt pressure at the die interface.
Sizing the tube profile immediately after extrusion is critical. Utilizing automated vacuum control loops, our sizing tables maintain constant internal pressures down to ±0.1 kPa. Multi-nozzle spray structures apply uniform cooling configurations to lock in geometry and eliminate internal material stresses.
Uniform linear tension is key to avoiding ovality. Our precision belt pullers (TKB series) and crawler-type haul-offs (TKC series) are driven by high-performance servo motors. These systems synchronize directly with extruder speed, eliminating stick-slip issues during high-speed production.
For flexible or thin-walled pipes, the FQ Series Rotary Fly Knife Cutter offers high-speed, dust-free cutting. Servo-driven rotary blade profiles sync dynamically with the product line speed to deliver clean, right-angle cuts without structural deformation.
The SPS-Dh and related custom winder systems offer automatic spool changeover and precise traverse displacement control. Tension control algorithms ensure the extruded tube is wound under uniform stress, protecting thin-walled tubing from collapse.
Used dynamically for PA, PE, PP, or PVC single-wall corrugated pipe processing. Mold blocks move on optimized closed loops under vacuum or blow-air systems, ensuring perfect rib structures for automotive harness tubes or medical respirator hoses.
Operating out of Jiangsu and Shanghai, BAOD EXTRUSION harnesses China's industrial clusters. This local infrastructure supports deep collaboration across steel procurement, raw casting, precision machining, heating component fabrication, and advanced PLC control integration.
By consolidating core manufacturing processes in our 16,000 m² factory, we bypass the supply chain bottlenecks that often challenge European or North American operations.
From mechanical fabrication to electronics configuration, BAOD manages every phase of production. We build systems that meet CE, ISO9001, and UL safety standards.
Automotive OEM lines require multi-layer polyamide (PA11/PA12) tubes and TPV fluid paths. The extrusion units must withstand high melt pressures while managing precision co-extrusion crossheads. Downstream calibrators and dual-stage vacuum tanks ensure structural integrity, preventing fuel vapors from leaking.
Cleanroom environments rely on our custom PVC medical tube extrusion lines. The vacuum tables feature closed-loop water filtration and non-contaminating components. Precision fly knife cutters slice catheter tubes cleanly, preventing plastic deformation to guarantee patient safety.
TPV/PVC sealing profiles require co-extrusion with metal carrier inserts. Our downstream units utilize caterpillars with variable speed profiles and punching machines. These features allow manufacturers to produce seals that meet tight tolerances for automotive wind-noise suppression.

Looking toward 2030, the extrusion industry is prioritizing two core pillars: intelligent automation and material versatility. The development roadmap for our extrusion lines focuses on integrating Internet-of-Things (IoT) sensors, real-time cloud analytics, and adaptive closed-loop controllers.
Integrating optical sensors with the haul-off and extruder screw drives. This design enables the system to dynamically adjust speeds, compensating for slight fluctuations in melt pressure to maintain tight product tolerances.
Adapting screw profiles and melt zones to handle post-consumer recycled (PCR) plastics and biodegradable polymers (such as PLA and PHA), which exhibit different thermal properties compared to virgin polymers.
Predictive maintenance modules monitor temperature drift and wear profiles on the screw, reducing unplanned downtime by up to 30%.
Upgraded heating bands and barrel insulation blankets cut energy usage by up to 25% across all SJ Series Extrusion units.
Integrating downstream scrap-detection systems with upstream grinding and feeding units to recycle start-up scrap on the fly.
Industrial equipment requires dependable, long-term support. BAOD EXTRUSION provides complete engineering backup, global shipping, and certified compliance options to ensure reliable performance worldwide.
All machines meet CE and ISO 9001 standards. We customize control layouts to comply with regional electrical and safety codes, including UL (USA), CSA (Canada), and GOST (Eurasia).
Our logistics team packages all components in heavy-duty, anti-corrosive wooden crates. They manage sea, rail, and air freight logistics, handling custom clearance documents for smooth delivery.
We offer remote diagnostics via secure VPN links, allowing our software engineers to update PLC programs instantly. For physical setups, our technicians travel worldwide to manage installation and train operators.
Our vacuum calibration tanks utilize auto-regulating vacuum valves and multi-chamber water layouts. Sensors monitor internal pressure variations, letting the PLC adjust water flow and vacuum levels (accurate to ±0.1 kPa). This prevents wall-collapse or deformation, even on high-speed lines processing thin-walled tubes.
Bimetallic components feature an alloy lining (typically tungsten carbide or nickel-chrome alloys) inside the barrel and on the screw flights. This design offers excellent wear resistance against abrasive polymers, glass-reinforced engineering resins, and additives, extending screw lifespan by 3 to 4 times compared to standard nitrided steel.
The FQ Series uses grease-free, food-grade mechanical bearings and a sealed servo motor. The cutting chamber is designed to minimize dust and micro-particles, and it can be integrated with HEPA vacuum extraction. This helps the unit meet Class 10,000 / ISO ISO 7 cleanroom medical standards.
Yes. Our SJ Series Extruders and downstream units are designed for easy integration. We can configure our machinery to work with co-extrusion die-heads or crossheads from other suppliers, utilizing custom adapters and shared communication buses (e.g., Profinet, EtherCAT, Modbus) for synchronized line control.
The SPS-Dh uses a pneumatic dancer arm or load cell linked to the drive controller. As the spool fills, the PLC calculates the changes in diameter and adjusts torque dynamically. This maintains a constant winding tension, preventing thin-walled pipes from stretching or compressing on the spool.
