BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was established in 2002, specializing in the design, fabrication, and global sales of custom high-end plastic extrusion machinery. Leveraging over 25 years of engineering experience originating from the KINGSWEL GROUP investment in 1999, we produce elite-level extrusion units designed for modern smart factories.
Sub-millimeter tolerance control for micro-bore and multi-layer configurations.
Maximum throughput rate optimized for custom Polypropylene (PP) compounds.
Integrated PLC diagnostics, smart closed-loop sizing, and zero-waste cutting.
Polypropylene (PP), a semi-crystalline thermoplastic polymer, is widely recognized for its robust chemical resistance, excellent flexural fatigue limit, high heat resistance, and structural stability. However, executing a custom Polypropylene tube extrusion line requires precise mechanical design due to PP's rheological complexities. Unlike amorphous polymers, PP exhibits high melt elasticity and distinct crystallization kinetics during cooling. This article dissects the design and engineering considerations crucial for custom manufacturing partners to achieve superior dimensional tolerance and high throughput.
The processing window of Polypropylene generally falls between 200°C and 250°C. Achieving precise temperature controls is critical because even minor thermal variations can lead to significant changes in melt viscosity and downstream dimensional deviations.
Due to polypropylene's high shrinkage rate (typically 1.5% to 2.5%), the vacuum calibration and cooling process are highly critical stages of the line. The vacuum sizing sleeve (calibrator) utilizes a microscopic water ring structure to reduce friction. This ensures smooth surface finishes on the tubes while pulling the hot melt onto the calibration wall. Sub-atmospheric pressure inside the calibration tank forces the tube outward, solidifying the outer layer and locking in the critical outer diameter (OD) and roundness.
Industrial procurement managers evaluate equipment not only based on initial capital cost, but on Total Cost of Ownership (TCO) and system integration capabilities. Today's global buyers require integrated PLC controls (such as Siemens S7-1500 architectures) that support data exporting for ERP tracking, closed-loop outer diameter and wall thickness measurements, and automated high-speed cutters that minimize scrap during changeovers.
Manufacturing precision industrial equipment in China provides global companies with a unique combination of speed, scale, and advanced engineering capabilities. By relying on Jiangsu Baodie Automation Equipment Co., Ltd., clients leverage regional supply chain clusters that dramatically reduce lead times for complex, custom steel components, high-precision machining, and custom electrical enclosures.
Our facility is situated in Jiangsu, adjacent to Shanghai. This location gives us direct access to high-grade steel mills and premium heat-treatment centers. All extruder screws and barrels are fabricated using high-durability nitrided steel (38CrMoAlA), ensuring long operating lives even when processing glass-fiber reinforced PP compounds.
Every custom extrusion line leaving our assembly floor is engineered to meet target regional requirements. From CE markings for European customers to UL-certified control boxes for North American factories, we conform strictly to industrial safety protocols:
To support global manufacturers, we offer comprehensive pre-installation layout consulting, remote diagnostics via secure VPN connections, and localized maintenance partnerships. Our engineers assist in debugging process setups, optimizing cooling speeds, and providing training programs for operating crews. This ensures rapid startup times and minimizes production downtime.
At Booth 7.1C04 in Shanghai, BAOD showcased its "Smart Extrusion" setups, featuring energy-saving systems and closed-loop process tracking.
Recognized for supplying ultra-precise, spark-free safety lines for technical mining and civil infrastructure projects worldwide.
Analyzing micro-extrusion flow dynamics in China vs European standards, detailing wall thickness controls and co-extrusion die designs.
We mitigate PP shrinkage variations through precision-machined vacuum calibration systems and multi-stage cooling tanks. The water temperature is closely monitored using electronic valves, preventing rapid crystallizing stresses that cause wall deformation.
For PP compounds filled with calcium carbonate or glass fiber, we supply bimetallic barrels and screws with high-resistance coatings. These feature custom compression zones designed to prevent fiber breakage and screw wear while maintaining output stability.
Yes. Our extrusion lines come standard with PLC systems supporting Ethernet/IP or Profinet protocols. This allows real-time integration with shop-floor execution systems (MES) and remote system monitoring.
Yes. Our screw configurations and die profiles are highly adaptable. By fine-tuning the temperature profiles and calibration settings, operators can run PE materials on the same line, making it a versatile asset.
