BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to the research, design, manufacturing, and global sales of advanced plastic extrusion equipment. Leveraging over 25 years of Taiwanese technical expertise originally commercialized via our parent enterprise (KINGSWEL GROUP) in Shanghai in 1999, we build state-of-the-art machinery engineered for maximum precision, reliability, and automation.
Our long-term commitment to continuous research and development is focused on four core technology pillars:
Designing production systems for automotive-grade PVC (Polyvinyl Chloride) tubing demands a deep understanding of thermal sensitivity, precise shear rate controls, and rapid cooling mechanics. These lines are built to handle structural requirements like oil resistance, flame retardance, and flexible mechanical tolerances.
Our SJ-series single screw extruders use custom L/D (Length/Diameter) ratios of 28:1 to 33:1. This optimizes melt homogeneity while preventing localized thermal degradation of PVC, utilizing specialized barrier-type screw designs and precise ceramic heating bands paired with air-cooling fans.
Achieving structural roundness and wall thickness tolerances within ±0.03mm requires multi-chamber vacuum calibration. Stainless steel sizing sleeves match the exact shrinkage profile of the polymer, supported by closed-loop water temperature control systems.
Belt or caterpillar-type pullers feature servo-controlled synchronization to prevent tube deformation during high-speed pulling. The rotary fly knife cutter provides clean, burr-free cuts, reducing post-processing steps.
For tier-1 automotive suppliers and OEM purchasing teams, selecting the right extrusion machinery goes beyond base pricing. High-precision manufacturing systems must consistently deliver high yields with minimal down-time. We engineer our platforms around key procurement metrics:
| Procurement Metric | BAOD System Implementation Details | Operational Advantage |
|---|---|---|
| Dimensional Tolerances | Laser diameter gauges coupled with closed-loop haul-off speed adjustments. | Consistent compliance with SAE, DIN, and ISO standards. |
| Melt Stability | Bimetallic barrels with high-hardness wear-resistant screw coatings. | Extended service life under filled PVC conditions. |
| Equipment OEE | Siemens/Omron PLC automation with remote ethernet maintenance portals. | Reduced unscheduled downtime and fast remote support. |
| Traceability | Continuous sensor data logging for pressure, temperature, and speed. | Easy integration with factory MES/SCADA systems. |
Modern automotive component production requires smart data architectures. Our extrusion control systems provide direct communication interfaces to help you manage variables such as raw material changes, thermal variations, and mechanical wear. This level of system intelligence helps reduce scrap rates during production starts and tool changes.
Additionally, our machines incorporate modular extrusion dies that allow operators to switch configurations between single-layer protective tubing, multi-layer co-extrusion for composite tubes, and special profiles with minimal tooling changes.
Located in Jiangsu's industrial machinery corridor near Shanghai, BAOD EXTRUSION operates within one of the world's most robust manufacturing ecosystems. Our facility draws on a highly integrated supply chain of precision components, high-grade metals, and specialized engineering partners. This concentration of resources enables us to offer:
Deploying machinery internationally requires adherence to local electrical standards, pressure laws, and operating codes. We configure and document every machine to meet local requirements:
We guarantee documentation compliance and support for:
Flexible PVC sleeves are used to protect wiring harnesses in engine bays and undercarriages from moisture, oils, heat, and vibration.
Designed for battery pack thermal cooling runs, A/C condensation drains, and windshield washer lines, ensuring long-term flexibility without cracking.
As electric vehicles scale, thin-wall plastic sleeves with custom profile geometry are increasingly used to protect coolant tubes from mechanical wear and high voltage arcs.
The automotive industry's push toward lightweight structures and electric powertrains is changing plastic tubing requirements. Future systems will need to support bio-based or recycled PVC resins while maintaining strict wall thickness consistency. Modern vehicle designs require thinner tube walls to save space and weight without sacrificing burst pressure strength. Our co-extrusion technology adapts to these changes by layering barrier resins alongside flexible carriers, helping you stay ahead of shifting automotive standards.
Designed for ultra-precise micro-tubing, featuring high stability calibration tables and servo pullers.
Advanced co-extrusion system for automotive fuel and vapor lines using polyamide polymers.

Our systems maintain outer diameter and wall thickness tolerances within ±0.03 mm. This accuracy is enabled by closed-loop control systems integrating laser measurement gauges, vacuum sizing tables, and digital servo puller synchronization.
We design custom L/D ratios (ranging from 28:1 to 33:1) and compression profiles matched to the formulation properties of automotive PVC. Combined with ceramic heating and forced air cooling, this maintains precise temperature control within ±1°C.
Yes. We provide specialized co-extrusion feedblocks and tooling configurations that allow multi-layer setups. This enables combinations of different polymers for specialized properties like fuel barriers, color striping, or soft-hard combinations.
We manufacture panels to comply with European CE directives and custom UL/CSA layouts for North American projects. Detailed manuals, circuit diagrams, and compliance certificates are included with every delivery.
