Baodie
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was established in 2002. We specialize in designing, manufacturing, and servicing industrial-grade plastic extrusion machinery. Guided by a legacy of 18 years of precision engineering in Taiwan, the original parent enterprise (KINGSWEL GROUP) set up its Shanghai extrusion manufacturing operations in 1999 to establish a global production hub.
With a historical background spanning 25 years in plastic extrusion machinery design, BAOD continues to pioneer advancements in:
By combining high-precision design methodologies developed in Taiwan with state-of-the-art manufacturing automation, Jiangsu Baodie produces machinery capable of tight-tolerance extrusion that holds up to the rigorous standards of modern global automotive assembly plants.

The rise of Electric and Hybrid-Electric platforms requires a massive shift in profile design. Modern battery packs need lightweight structural sealing, high-voltage insulation sleeves, and complex multi-lumen cooling tubes. Our custom profile extrusion lines are specifically engineered to produce components that withstand high battery temperatures and guarantee electrical isolation.
Passenger compartment noise mitigation is key. Wind noise is suppressed through high-precision TPV and PVC weatherstripping profiles. These sealing profiles feature multi-material co-extrusion technology, combining solid structural matrices with micro-foamed cellular structures to optimize clamping force and acoustic absorption. Our machinery achieves co-extrusion tolerances of ±0.05 mm.
Engine and battery thermal management require high-integrity coolant tubing. These hoses must resist aggressive chemical environments, glycol solutions, and continuous operating pressures. Our multi-layer co-extrusion lines produce smooth and corrugated PA/PE/PP/TPV hoses that prevent fluid permeation and maintain mechanical flexibility under extreme temperatures.
The worldwide automotive supply chain expects reliable manufacturing lines that can run 24/7 without material variation. Traditionally, European OEM machinery dominated the high-end precision automotive market. However, companies like BAOD EXTRUSION are shifting the industry balance.
We combine high-performance, DIN-compliant European mechanical designs with cost-effective Chinese supply chain management. This results in custom extrusion lines that match European precision (e.g., DIN 74324/DIN 73378 for air brake tubes) at a lower total cost of ownership.
From North America to the European Union and Southeast Asia, our lines are selected for their quick material changeovers, low raw material waste (scrapless startups), and digital controls that integrate directly into automotive MES (Manufacturing Execution Systems).
Our extruders use high L/D ratios (usually 30:1 or 33:1) with specialized barrier screws. Coupled with a loss-in-weight gravimetric feeding system, they prevent fluctuations in melt density. This ensures consistent wall thickness and output pressure even when processing difficult materials like TPV or UHMWPE.
For high-precision hoses and profiles, we integrate a multi-chamber vacuum calibration tank. This setup continuously measures the outer diameter using laser scanners, feeding data back to the puller and vacuum valves. It maintains dimensions within tolerances of ±0.03 mm in high-speed operations.
Downstream reliability determines overall line efficiency. Our servo-driven TKC Crawler-Type Pullers and QYP Belt Pullers provide smooth pulling force without marking or distorting profiles. The FQ Series Rotary Fly Knife and SC Saw Blade Cutters deliver clean, burr-free cuts at high line speeds, synchronized with the extrusion velocity.
To support international operations, BAOD builds all machinery under strict quality and electrical compliance guidelines. Every system is fully documented and built with high-quality components from brands like Siemens, ABB, Omron, and SMC.
These profiles require multi-layer co-extrusion to bond rigid substrate materials with soft sealing lips and low-friction flocking or slip coatings. BAOD's co-extrusion die heads control the distribution of TPV or PVC, ensuring clean, continuous boundaries between materials. This improves structural fit and guarantees weather tightness.
Automobile fuel lines must prevent hydrocarbons from leaching into the environment. This is achieved using multi-layer tubing with thin barrier layers of EVOH or PVDF inside PA11/12 structures. BAOD co-extrusion lines feed up to 5 layers through a single high-precision die head. This layout ensures uniform layer distribution and strong adhesion across the entire tube profile.
Automotive wiring harnesses must be protected from heat, abrasion, and moisture. Our high-speed single-wall corrugated pipe extrusion lines feature advanced mold blocks and vacuum forming technology. This design enables fast production speeds while keeping the corrugation peaks uniform, ensuring structural flexibility and long-term durability.

Our lines are engineered to meet tight industrial requirements. Under stable, continuous operation with gravimetric feeding and closed-loop laser gauge controls, we regularly achieve dimensional tolerances as low as ±0.03 mm for single-layer hoses, and ±0.05 mm for complex co-extruded TPV/PVC weatherstripping profiles.
Yes, our machines can be configured for both materials. However, because TPV (thermoplastic vulcanizates) and PVC (polyvinyl chloride) have different melting temperatures and shear behaviors, we customize the screw geometries, barrel cooling systems, and die head flow channels to suit the specific rheology of the material you choose.
We use specialized co-extrusion cross-head dies with adjustable flow channels, paired with high-precision melt pumps. Additionally, ultrasonic wall thickness monitors are integrated into the cooling lines to measure the thickness of individual layers in real time, allowing operators to make precise adjustments.
We offer full installation support, including on-site setup, calibration, and training for your operators. Every extrusion line is also equipped with a secure remote industrial VPN module. This allows our support team to access the control panel remotely, troubleshoot software settings, and assist your engineers in real time.
