BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to the design, manufacturing, and sales of high-performance plastic extrusion equipment. Based on 18 years of experience designing and fabricating high-quality machinery in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing our modern extrusion manufacturing base in Shanghai in 1999, subsequently expanding to Jiangsu to scale operations.
Our units of extrusion line incorporate state-of-the-art closed-loop pressure control systems, gravimetric dosing units, and custom-designed screw elements to address the exact shear requirements of advanced polymers (TPV, Fluoroplastics, Multi-layer PA, and PVC).
By designing each downstream modular unit (sizing tanks, pullers, cutters, and coilers) to communicate directly with the main PLC system, we ensure minimal material scrap during startup—a vital competitive advantage for Indian manufacturers managing fluctuating raw material costs.
India's plastics processing sector is undergoing a rapid, technology-driven evolution. Supported by national development plans like the "Make in India" initiative and specialized Production Linked Incentive (PLI) schemes for medical technology, electronics, and automotive parts, local factories are moving away from traditional, low-margin profiles. Instead, they are prioritizing high-end precision products. Today’s industrial landscape demands advanced, reliable units of extrusion lines that can handle challenging technical polymers while operating efficiently under local environmental conditions.
Our systems are built to withstand voltage fluctuations in industrial hubs like Pune, Gujarat, and Noida. Heavy-duty stabilizers and high-efficiency motors protect critical electronics.
Designed with dual-stage vacuum calibration cooling systems. These units maintain high calibration speeds even during peak summer temperatures exceeding 45°C.
Integrated variable frequency drives (VFD) and optimized heating zones lower power consumption per kilogram of output, lowering operational overheads.
Historically, Indian processors relied on either highly expensive European machinery or lower-cost local setups that lacked the precision needed for modern industrial components. Jiangsu Baodie bridges this gap by combining precise, Taiwan-origin mechanical designs with high-volume manufacturing capabilities. This approach offers a balanced solution: high performance and precision coupled with manageable capital expenditures.
In the global market, manufacturing standards demand complete automation, continuous material savings, and traceably high quality. To meet these expectations, our extrusion lines feature closed-loop dimensional controls. These systems constantly measure external pipe diameters and wall thicknesses, feeding data back to the puller and extruder units to make real-time, automatic corrections. This level of technology helps Indian export-oriented manufacturers confidently meet strict European and American quality requirements.
A high-performance extrusion line is only as strong as its weakest component. Each downstream unit plays a vital role in maintaining the structural integrity and dimensional tolerance of the final profile:
The raw polymer is melted and homogenized within the barrel. Our SJ Series features custom-designed L/D (Length/Diameter) ratios tailored for specific resins. For example, processing heat-sensitive polymers like PVC or engineering plastics like Fluorine polymers requires specialized screw geometries. These designs prevent degradation, control material shear, and deliver a smooth melt flow directly into the tooling.
Immediately after leaving the die, the molten polymer is shaped and cooled. The Precision Auto Vacuum Sizing Tank and Vacuum Calibration Cooling Table create a stable, low-pressure environment. Water temperatures and vacuum levels are precisely controlled, locking in the product's circular shape and dimensions without introducing internal stresses. This process is essential for producing high-precision medical-grade multi-lumen tubing.
Consistency in pull rate directly determines the wall thickness and overall stability of the extrusion process. The puller must exert constant, slip-free tension without crushing or distorting the profile. Our crawler and high-speed belt pullers use precision servo motors. These sync directly with the extruder's PLC, maintaining steady tension even at high production speeds.
The extrusion process must be continuous, but product delivery must adapt to specific lengths. For rigid products, the Follow-Up Saw Blade Cutter travels along with the pipe to make clean, square cuts before returning to its starting position. For flexible tubing, Rotary Fly Knife Cutters deliver rapid, burr-free cuts at high cycle rates. Finally, our high-speed, dual-spool automatic winding machines spool the finished tubing neatly, allowing operators to change spools without pausing the line.
BAOD EXTRUSION showcased its latest R&D achievements, presenting “Smart Extrusion & High-Efficiency Innovation” solutions designed to assist global processors in optimizing raw material consumption.
In infrastructure and quarrying, detonating shock tubes require extreme wall thickness consistency. BAOD's custom lines ensure reliable, high-speed output with integrated safety mechanisms.
Catheters and medical tubes demand micro-lumen channels with zero cross-contamination risk. We review the high stability metrics required to meet European medical standards.
To supply global automotive OEMs, fuel and cooling line manufacturers must pass strict stress tests. Our systems ensure consistent compliance by monitoring processes in real time.
We configure our machinery controls for the standard Indian utility voltage (415V, 3-Phase, 50Hz). Critical components—including PLC CPUs, sensors, and electromagnetic valves—run on isolated DC power systems protected by dedicated line filters. This prevents power fluctuations from disrupting continuous extrusion processes.
High ambient heat (up to 45°C) can affect cooling water efficiency, leading to dimensional variation in extruded profiles. To address this, our vacuum calibration spray tanks feature closed-loop temperature control valves. We also configure the piping for external chilling loops, ensuring consistent cooling performance regardless of local seasonal weather.
Yes. By customizing the screw profile and adjusting the L/D ratio of our SJ Series Extruders, our machines can process recycled HDPE, LDPE, PP, and biodegradable materials like PLA. This flexibility helps manufacturers meet domestic environmental regulations and reduce material costs.
Our medical extrusion lines consistently achieve tight dimensional tolerances, holding outer and inner diameter variations within +/- 0.02 mm. We achieve this by pairing servo-controlled pullers with digital vacuum regulation, which minimizes pressure fluctuations during sizing.
We provide comprehensive startup support. Our services include customized factory layouts, remote commissioning guided by experienced engineers, and on-site support through local technical partners to handle installation, electrical testing, and operator training.
Extruding materials filled with glass fiber or other abrasive additives can cause rapid wear on barrels and screws. To prevent this, we offer bimetallic barrels treated with specialized alloys. This treatment extends the service life of critical extrusion components, helping manufacturers maintain stable output over years of continuous operation.
