Rigid Polyvinyl Chloride (RPVC) is an indispensable material in modern industry, valued for its exceptional structural rigidity, chemical resilience, flame-retardant properties, and thermal stability. Unlike plasticized PVC, RPVC contains minimal to no plasticizers, which dramatically increases its stiffness but presents unique processing challenges due to its high melt viscosity and high thermal sensitivity.
Processing RPVC requires highly specialized machinery. Because the polymer chain degrades when subjected to excessive shear or temperature overshoots (releasing corrosive hydrochloric acid gas), the extrusion line must feature precise temperature control, low-shear screw configurations, and corrosion-resistant flow channels. Our custom RPVC profile extrusion lines are specifically engineered to mitigate these material limitations while achieving high-speed production output and precise dimensional stability.
Achieving micron-level tolerance in RPVC profile manufacturing demands seamless integration of multiple downstream and upstream units. Below is the system configuration utilized by BAOD Extrusion.
Equipped with high-performance conical twin screws or single-screw configurations optimized with bimetallic treatment. Features localized ceramic heating bands and continuous air cooling systems to prevent heat spikes.
Engineered through finite element analysis (FEA) to guarantee uniform flow velocity across the profile cross-section. Employs multi-stage vacuum calibrators with intense water cooling to solidify shapes instantly.
Uses TKC Crawler-type pullers or QYP belt pullers to provide continuous pulling tension without distorting the profile. Integrated with chipless rotary fly knife cutters for clean, right-angle finishes.

BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), established in 2002, is dedicated to the research, design, and manufacturing of high-end plastic extrusion systems. Building upon 18 years of advanced extrusion design experience rooted in Taiwanese manufacturing practices, our parent company (KINGSWEL GROUP) laid our foundational operations in Shanghai in 1999.
With an unwavering focus on precision extrusion, high-efficiency processes, state-of-the-art automation, and thorough safety configurations, we supply top-tier solutions to automotive, medical, construction, and telecommunication sectors worldwide.
Sourcing an RPVC extrusion line from a top-tier Chinese factory offers unique competitive advantages that balance financial efficiency with state-of-the-art technological capabilities. At BAOD Extrusion, we merge localized manufacturing agility with international standards.
Our location in Jiangsu places us in the heart of China’s most advanced machinery cluster. This enables immediate sourcing of raw materials, heavy machining capability, and rapid custom adjustments during production stages.
We build custom dies, adjust barrel geometries, and integrate customized downstream equipment within a fraction of the time required by European builders, reducing commissioning lead time significantly.
By pairing local high-precision assembly with top-tier components (Siemens PLC, Omron temperature controllers, ABB drives), we offer systems with low operational costs and high structural reliability.
Our RPVC profile extrusion lines are designed to adapt to a wide variety of industrial verticals. By modifying the cooling layout, die configuration, and material feeding parameters, we accommodate the demands of multiple global industries.
Rigid PVC is highly sought-after for window profiles, door frames, siding panels, and wall cladding due to its exceptional weatherability and mechanical strength. Our extrusion lines allow window and door manufacturers to run continuous multi-hollow profiles with internal metallic reinforcement guide channels, matching exact DIN standards.
Safety is the primary metric for electrical installations. RPVC provides excellent dielectric properties and is self-extinguishing. Our extrusion lines manufacture micro-cable trunking, large industrial cable conduits, and slotted wiring ducts with clean punch designs integrated directly into the downstream system.
By using co-extrusion technology, we can feed rigid structural PVC alongside flexible PVC or TPV elastomers in a single die header. This allows production of hybrid sealing strips that grip securely onto metal car bodies while keeping the dynamic door seal soft and flexible.
Our specialized medical-grade lines produce rigid plasticized and unplasticized PVC components used in fluid connectors, medical valves, and analytical instruments, meeting strict cleanroom specifications.
High-precision multi-layer nylon tube manufacturing line designed for automotive and industrial hose applications.
Medical catheter and tubing line featuring high line speeds, cleanroom design, and strict diameter tolerances.
High speed block forming system designed for protective electrical conduits and automotive wire harnesses.
Specialized composite structure combining knit reinforcement fibers with high performance TPV liners.
Designed for producing vehicle glass run channels and door weatherstripping using co-extrusion technology.
The global extrusion industry is undergoing rapid changes driven by digital transformation, resource efficiency, and sustainability targets. At BAOD Extrusion, we integrate these trends directly into our equipment design.
Modern RPVC extrusion plants require deep visibility into performance metrics. Our smart controllers stream motor torque, melt pressure, vacuum stability, and cooling temperatures in real-time, allowing operators to run predictive maintenance and auto-tune extrusion settings to reduce waste.
Sustainable manufacturing models require extruders to process post-consumer and post-industrial recycled PVC. Since recycled PVC can vary in viscosity and contamination levels, we design specialized venting barrels and melt filters to ensure stable extrusion output.
