About Jiangsu Baodie Automation Equipment Co., Ltd.

Pioneering automation and efficiency in global plastic extrusion engineering since 2002.

Decades of Engineered Precision and Innovation

BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), established in 2002, is dedicated to the professional design, manufacturing, and distribution of high-performance plastic extrusion machinery. Rooted in 18 years of advanced mechanical engineering and design heritage from Taiwan under our parent group, KINGSWEL GROUP, we established our mainland production headquarters in Shanghai in 1999 before scaling operations into Jiangsu.

Our company focuses on high-precision extrusion systems, integrating structural reliability with smart IoT controls. By maintaining an in-house R&D team, we optimize extrusion geometry, thermal control stability, and high-speed drawing parameters, delivering customized production lines for complex polymer profiles worldwide.

Key areas of long-term focus include precision tube calibration, micro-diameter tolerance management, multi-layer co-extrusion technology, and complete line synchronization.

Technical Architecture of BAOD Extrusion Machinery

An in-depth look at our mechanical design, thermal profiling, and down-stream automation modules.

Extrusion Die & Tooling Design

Our tool design incorporates advanced flow channel dynamics simulation to prevent stagnation and thermal degradation of rigid and plasticized PVC. High-chrome tool steel is hardened, polished, and chrome-plated to ensure a smooth finish and minimize die-swell.

The bimetallic barrel and nitrided screws feature custom compression ratios engineered specifically for PVC thermal sensitivities.

High-Precision Auto Vacuum Calibration

The vacuum sizing tank utilizes closed-loop water temperature and vacuum pressure regulations. This controls the crystallization rate of the polymer melt.

By combining high-pressure spray cooling with precise sizing sleeves, we guarantee circularity and dimensional tolerances within ±0.03mm.

Technical Roadmap & Future Outlook: Our R&D department is currently transitioning all line systems to dynamic Closed-Loop PLC architecture. By integrating ultrasonic wall-thickness measurement sensors directly with puller speeds and extrusion throughput, our next-generation systems achieve zero-waste start-ups and self-correction profiles.

Technical FAQ: Custom PVC Extrusion Machinery

Expert answers on material behavior, machinery calibration, and process parameters.

Q1: How does BAOD handle the thermal sensitivity of PVC during high-speed extrusion?

Rigid and flexible PVC are highly heat-sensitive polymers that degrade if exposed to high shear or hot spots. BAOD utilizes custom-designed screws with deep channel depths and progressive compression profiles to minimize shear heating. Our barrels feature dedicated multi-zone electric heating coupled with air-cooling fans, controlled by PID loops to keep temperatures within ±1°C of the target setpoint.

Q2: What is the benefit of using a bimetallic barrel and nitrided screw for PVC compounds?

PVC dry blends often contain abrasives like calcium carbonate (fillers) and release corrosive hydrochloric acid gas during processing. Our bimetallic barrels feature an alloy lining that resists wear and corrosion, extending operating life up to three times compared to standard nitrided steel under continuous-use conditions.

Q3: How does the auto vacuum sizing tank control dimensional tolerances in medical tubing?

Our vacuum sizing tank maintains a stable vacuum environment. A closed-loop control valve adjusts vacuum pressure according to line speed variations. The outer diameter of the tube is formed as it enters the vacuum sleeve, while high-efficiency water rings and submerged spray nozzles solidify the shape without causing thermal stress distortion.

Q4: Can BAOD lines handle co-extrusion of different hard/soft durometer polymers?

Yes. Our multi-layer co-extrusion technology integrates multiple extruders into a single crosshead die block. This setup allows for the co-extrusion of hard PVC for structural rigidity alongside soft PVC or TPV for sealing flaps, commonly used in automotive sealing profiles and building window frames.

Q5: What cutting systems are used for high-speed line operations?

We offer our FQ Series Rotary Fly Knife Cutters and Puller-Cutter combination systems. For flexible medical tubing, high-speed rotary fly cutters provide clean, burr-free cuts at high line speeds. For rigid profiles and corrugated pipes, we integrate planetary cutters or automated saw units to ensure perpendicular cut ends.

Q6: How does BAOD ensure consistent wall thickness in multi-lumen catheters?

We use specialized internal air regulation systems that precisely feed low-pressure air into each lumen. This is paired with an ultrasonic thickness measurement system mounted directly after the sizing tank. The PLC monitors wall thicknesses in real-time, feeding correction signals back to the extruder drive motors to maintain target dimensions.

Q7: What is the average energy saving on BAOD's high-efficiency lines?

By utilizing permanent magnet synchronous motors (PMSM) and optimized high-torque gearboxes, our systems reduce electrical consumption by up to 20-30% compared to traditional AC motor setups. Additionally, the barrel heating zones feature thermal insulation blankets to minimize heat loss.

Q8: How does the auto-spool winding machine prevent tension deformation in flexible tubes?

Our traverse displacement auto-spool coiling machines use tension-feedback dancer arms. The servo-driven spindle dynamically adjusts its rotational speed based on winding diameter and tension readings, preventing deformation or stretching of thin-walled tubes during spooling.

Q9: What types of corrugation forming systems are available for high-speed pipe extrusion?

We build continuous horizontal corrugation forming machines utilizing chilled block circulation. These blocks are driven by a high-precision gear transmission system. A vacuum forming design draws the heated tube wall tightly against the mold blocks, ensuring well-defined corrugation geometry even at high output speeds.

Q10: What is the typical installation and commissioning timeframe for a new line?

Typically, installation takes 7 to 10 days once the machine arrives at your facility. This includes placing the equipment, connecting electrical and water supplies, running dry-run calibration, conducting live material extrusion trials, and training plant personnel.
