An Industry Whitepaper on Melt Rheology, Dynamic Vulcanization Control, and Precision Die Design
Unlike standard thermoplastics, Thermoplastic Vulcanizates (TPV) present unique processing challenges due to their dual-phase structure. TPV consists of fully crosslinked elastomer particles (typically EPDM rubber) dispersed within a continuous thermoplastic matrix (usually Polypropylene). Extruding this material requires specialized screw geometries, precise temperature profiles, and exceptional shear management to prevent material degradation while ensuring a smooth, matte finish that matches automotive OEM standards.
A key focus in modern automotive sealing systems is replacing traditional thermoset rubber (EPDM) with TPV. This transition is motivated by a significant reduction in overall component weight (up to 30%), built-in recyclability, and the capacity for multi-material co-extrusion with stiff PP cores or metal reinforcements in a single line pass.
Modern automotive weatherstripping is rarely a single compound. Multi-durometer extrusion lines combine hard TPV (for the structural, clip-on base) with soft TPV (for the flexible sealing bubble or lip). Furthermore, some profiles integrate a third compound—such as low-friction slip coatings—or require the embedding of a metal carrier (steel wire or stamped steel strip) inside the profile to maximize door grip performance.
BAOD's specialized TPV die heads feature computational-flow-dynamic (CFD) balanced runners. This guarantees balanced flow velocities across multi-layer profiles, preventing internal stresses that cause post-extrusion warping. Accurate water-spray cooling and vacuum sizing calibration units then freeze the complex shape instantly, securing strict tolerance controls.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), established in 2002, is committed to the design, manufacture, and sales of high-end plastic extrusion machinery. Leveraging 18 years of experience in engineering and fabricating premium machinery in Taiwan, our parent group (KINGSWEL GROUP) invested in setting up a state-of-the-art extrusion manufacturing base in Shanghai in 1999.
Today, our focus spans over 25 years of research, design, and manufacturing in plastic extrusion, positioning us as a premier factory. We supply complete turnkey systems designed for maximum precision, outstanding efficiency, high-level process automation, and extensive operator safety measures.
Continuous innovation in plastic extrusion since the initial design footprints in Taiwan and Shanghai.
Equipped with high-precision CNC machining centers, testing bays, and assembly lines to handle massive projects.
A dedicated team of design engineers, R&D specialists, QA technicians, and global support engineers.
Serving critical global industries with tailored tooling designs and compound configurations.
Providing custom multi-component glass run channels, door seals, hood-to-cowl gaskets, and trunk seals. The lines manage tight tolerances and allow in-line flocking or slip coating application for reduced friction against glass.
TPV seals display superior UV stability and ozone resistance compared to standard PVC. Our extrusion lines manufacture heavy-duty window frame gaskets, building expansion joints, and roofing sheet profiles capable of withstanding extreme weather.
TPV seals are widely integrated in household washing machines, dishwashers, and food-handling machinery due to FDA-compliant compound grades. The extrusion lines achieve high-speed profiles with precise physical properties.

Handles PA11/PA12 multi-layer fuel line systems with smooth walls or online corrugated formatting integration.
Achieves exceptional production velocities with medical grade PVC, maintaining roundness tolerances and cleanroom compliance.
Engineered for high-output manufacturing of protective automotive harness tubing and flexible plumbing hoses.
Incorporates online yarn-knitting reinforced structures with double-layer TPV coatings for extreme-pressure fluid transfer.
The definitive tooling and calibration setup for complex automotive glass run channels, featuring metal-insertion technology.
Where high-performance engineering meets next-generation digital factory systems.
By integrating neural network feedback systems, our future extruders autonomously adjust melt temperatures, screw speeds, and melt pump parameters in real time. This keeps dimensional variation below ±0.03 mm, even when processing variations occur within raw TPV material lots.
To support corporate ESG mandates, BAOD is developing specialized in-line scrap reprocessing technology. This module feeds start-up scrap and profile trimmings directly back into the secondary extruder, ensuring zero waste during the run without sacrificing the seal's mechanical properties.
We are advancing our electrostatic flocking modules and PU coating stations to run in-line at speeds up to 35 meters per minute. Our goal is to ensure strong adhesion between TPV profiles and coatings without the need for toxic primers.
Multi-manifold die architecture enables the combined processing of up to four materials simultaneously (soft TPV bulb, hard TPV foot, metal backbone, and PU slip coat) on a single extrusion line.
Combining complete supply chain integration with world-class engineering standards.
Located in the Yangtze River Delta industrial hub, BAOD leverages deep relationships with global component partners (Siemens, ABB, Yaskawa, Omron) and high-quality local raw material producers. This ensures rapid spare parts availability and lower overall component costs.
With a 16,000 m² state-of-the-art facility, we can construct, commission, and wet-test up to 15 complex extrusion lines simultaneously. This scale allows us to deliver complete production systems within 60 to 90 days, significantly faster than European equivalents.
Buying directly from BAOD cuts out middleman markups. Our customers receive high-quality machinery built with durable components, fully optimized extrusion dies, and tailored downstream equipment at competitive prices.
We ensure seamless line installation, regulatory compliance, and localized maintenance across the globe.
All extrusion machinery built by BAOD is engineered in strict compliance with the European Machinery Directive (2006/42/EC) and carries CE certification. For North American markets, our control panels are engineered to UL508A and NFPA 79 specifications, ensuring smooth inspections and local operator safety.
Our structures comply with local plant safety standards, featuring enclosed puller cabins, dual-circuit safety doors, interlocked emergency stops, and low-dB vacuum pumps to keep noise levels down.
Equipped with secure industrial VPN routers, our PLC systems support real-time remote diagnostics. This allows our engineers in China to assist with fine-tuning die pressure curves, monitoring thermal profiles, and updating code remotely.
We also collaborate with regional service partners across Europe, North America, and Southeast Asia to provide rapid on-site commissioning, operator training, and local spare parts delivery.
