Explore our core engineering products designed for maximum dimensional stability, continuous output, and optimized energy efficiency.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is dedicated to the high-performance design, meticulous fabrication, and global distribution of advanced plastic extrusion machinery. Leveraging over 25 years of engineering experience in Taiwan and mainland China, the original parent entity (KINGSWEL GROUP) initiated extensive manufacturing operations in Shanghai in 1999, before establishing our specialized modern facility in Jiangsu.
Our commitment revolves around engineering solutions that integrate high-precision control, energy conservation, automated processing, and operator safety. Every machine is calibrated to deliver tight-tolerance dimensional stability under continuous operational stresses.

We systematically invest in barrier screw configurations, high-pressure die head optimization, and automated downstreams to ensure that raw materials like HDPE, LDPE, PP, PA, and TPU are processed at peak thermodynamic efficiency.
An in-depth look at structural design, thermodynamic behaviors, and mechanical factors governing the production of High-Density Polyethylene filaments and micro-tubes.
High-Density Polyethylene (HDPE) features a high crystalline structure and a tight molecular weight distribution. To achieve perfect filament cross-sectional tolerance (often within ±0.02 mm), the extruder's screw must design with custom L/D ratios of 30:1 or 33:1. This ensures consistent shear forces and uniform melt temperature distributions, eliminating polymer degradation or micro-voids.
The transition of melt from the cylindrical screw barrel to the micro-filament geometry requires advanced spiral mandrel dies or co-extrusion crossheads. Minimizing melt fracture and managing die swell are crucial. Downstream vacuum calibration and pressurized cooling channels precisely control the cooling rate, stabilizing the amorphous phase before crystallization sets in.
The correlation between extruder output speed, puller tension, and coiling torque dictates the final diameter consistency. BAOD lines leverage high-end servo motors coupled with closed-loop PID control loops. Real-time diameter gauges continually feed back dimensional data to the PLC, allowing automated micro-adjustments of puller speeds on the fly.

Combining complete supply-chain resilience with European-compliant precision engineering standards at BAOD Extrusion.
1. Vertically Integrated Supply Chains: Jiangsu Baodie is located in China's premier machinery manufacturing hub. This proximity allows immediate access to specialized metallurgical processing, top-tier heat-treatment facilities, and precise auxiliary component manufacturers. We pass these efficiency gains directly to our global client base.
2. Taiwanese Design Heritage & Shanghai R&D Roots: BAOD's engineering foundations derive from 18 years of high-quality machinery manufacture in Taiwan via KINGSWEL GROUP. Having set up our Shanghai base in 1999, we merged rigorous Taiwanese design templates with scalable mainland manufacturing systems.
3. Deep Customization Capabilities: Unlike rigid Western production pipelines, BAOD can adapt feed blocks, screw designs, vacuum tanks, and automation workflows to process specialized materials like post-consumer recycled (PCR) HDPE, highly filled HDPE composites, or multi-layer functional pipelines.
4. Strict Compliance & Quality Benchmarking: Every extrusion line developed in our 16,000 m² factory goes through intensive testing runs under simulated production loads before dispatch. Our mechanical and electrical configurations comply with CE directives, UL standards, and ISO 9001 quality management pathways.
5. Cost-to-Performance Ratio: By sourcing globally recognized electronic components (Siemens PLC, Omron temperature controls, ABB/Yaskawa frequency inverters) and combining them with in-house fabricated structural machinery, we provide highly competitive capital expenditures (CAPEX) with long-term reliability.
6. Comprehensive Post-Sales Engineering: Our technical team offers remote visual commissioning, PLC code updates over secure cloud connections, and field technician dispatch to facilitate immediate plant integration.
Explore customized machinery designed for distinct high-speed, multi-layer, and precision medical extrusion applications.
Modern production facilities demand cohesive, end-to-end plant layouts. BAOD EXTRUSION supplies turnkey micro-tubing and filament extrusion line systems starting from raw material handling (drying, volumetric dosing, gravimetric feeders) to closed-loop melt-pump integration, precise extrusion head systems, optimized multi-stage cooling lines, pulling caterpillars, and high-speed traverse auto-winders.
By implementing a centralized SCADA system, our machinery communicates essential performance data back to centralized execution systems (MES). This facilitates predictive maintenance alerts, tracks resin consumption metrics, and decreases scrap rates to optimize bottom-line efficiency.
