Explore our top-tier precision production assemblies engineered for global pipe, tube, profile, and sheath manufacturers.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) represents the cutting edge of plastic extrusion plant fabrication. Founded in 2002, our foundations rest on nearly three decades of engineering refinement. Our origins trace back to 18 years of designing and fabricating high-quality machinery in Taiwan under our original parent company, KINGSWEL GROUP, which later established our mainland manufacturing headquarters in Shanghai in 1999.
Today, we design and produce smart, automated, and highly energy-efficient extrusion lines that serve critical fields globally, including automotive tube routing, precision medical fluid pathways, complex multi-layer corrugated hoses, and municipal infrastructure. We continuously optimize processing parameters to deliver maximum melt homogeneity, high-output stability, and strict dimensional tolerances for complex polymers.
Our systems comply with directives defined by ISO9001:2015 and European CE safety requirements. We bridge the gap between Chinese price efficiency and European reliability guidelines, making BAOD the premier choice for demanding industrial and civil pipe plants globally.
How modern factories navigate shifting material parameters, energy efficiency standards, and infrastructural scaling.
Polyvinyl Chloride (PVC) remains a cornerstone material in global civil engineering, electrical conduit grids, and agricultural irrigation networks. However, modern industrial challenges demand a shift in processing methodologies. Traditional single-layer heavy-gauge PVC lines are giving way to advanced, energy-efficient multi-layer structures, chemical-resistant chlorinated PVC (CPVC) formulations, and oriented PVC (PVC-O) processing pipelines.
Globally, processors struggle with the high cost of thermal stabilizers, energy consumption fluctuations, and raw material variations. China's manufacturing base has responded by developing high-capacity extruders equipped with dynamic cooling systems, bi-metallic screws, and precise loss-in-weight gravimetric dosing units. These innovations dramatically lower the overall Cost of Goods Sold (COGS) while maintaining compliance with international ASTM, ISO, and DIN standards.
Setting up a modern PVC extrusion facility involves more than positioning an extruder next to a cooling bath. It demands a holistic manufacturing plant design, including central dust-free feeding systems, high-speed mixing units (heater/cooler combinations), closed-loop water recirculation systems, and inline quality assurance integrations.
BAOD Extrusion acts as a strategic EPC partner, delivering complete turnkey plant designs tailored to specific regional parameters. Whether resolving extreme ambient temperature swings in Middle Eastern installation sites or meeting low-noise, energy-saving regulations in Europe, our tailored configurations guarantee steady melt pressures, optimal gelation levels, and minimum scrap rates during continuous 24/7 production cycles.
To deliver competitive *information gain* to plant managers, our engineers have drafted the roadmap below showing the milestones of a fully optimized smart extrusion system. Moving from manual operations to closed-loop AI diagnostics represents the frontier of modern plastic processing.
Specialized screw geometry designs with variable pitch and bi-metallic flight coatings. This ensures uniform shear and optimal plasticization, even with highly filled PVC compounds (high calcium carbonate loading).
Adopting automated multi-chamber vacuum calibration tanks. Closed-loop pressure regulation maintains stable pipe roundness and uniform wall thickness at high extrusion speeds.
Integrating ultrasonic wall thickness scanners and laser diameter monitors. These feed data back to the PLC, allowing real-time adjustment of haul-off speed and extruder RPM to eliminate deviations.
Our multi-layer co-extrusion technology enables the use of recycled core materials wrapped in virgin PVC skins. This not only reduces material costs by up to 35% but also satisfies strict regional environmental guidelines regarding the circular plastic economy.
Additionally, modern systems leverage high-precision gravimetric control systems. The exact weight of material per meter is monitored continuously, correcting for bulk density fluctuations in raw polymer powders. This level of process stability prevents over-dimensioning of pipes, saving thousands of tons of material annually.
By using energy-efficient permanent magnet synchronous motors (PMSM) across the extrusion screw drive, vacuum pumps, and haul-off pullers, BAOD systems reduce total electricity consumption by 18-25% compared to legacy installations.

We address this through optimized screw geometries and precise temperature control. Our twin-screw design features internal oil cooling, combined with copper-pipe cooling jackets on the barrel. This prevents localized shear heating and stabilizer depletion, maintaining polymer integrity at high throughput speeds.
Gravimetric dosing controls the raw material feed rate based on the continuous weight of the material entering the extruder. It syncs the extruder screw RPM with the haul-off speed. This keeps the pipe weight-per-meter variation under ±0.5%, saving material by preventing over-dimensioning.
We use mirror-polished extrusion dies and high-precision vacuum sizing sleeves. The vacuum level is controlled by dynamic closed-loop frequency-inverter pumps, avoiding the pulsation typical of older vacuum calibration tanks. This ensures smooth surface finishes and helps prevent bacterial adhesion in medical fluids.
For polyolefin materials (like PP/PE) and specialized profiles, we typically utilize a 28:1 or 30:1 L/D ratio. For heat-sensitive PVC formulations, we customize the ratio to ensure complete melting and gelation without degradation from excess residence time.
We supply comprehensive documentation, engineering drawings, and electrical layouts. Every production line undergoes running trials at our Jiangsu plant before shipping. Additionally, our field service engineers provide on-site setup, calibration, and training for local operators worldwide.
Yes. We specialize in co-extrusion technology. We can design three-layer configurations where recycled PVC or PE regrind forms the core layer, enclosed by virgin material skin layers. This maintains structural properties while reducing raw material costs.
