BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, is dedicated to the designing, manufacturing, and sales of high-end plastic extrusion equipment. Based on 18 years of experience in designing and fabricating high-quality machinery in Taiwan, our original parent company (KINGSWEL GROUP) invested in establishing our modern extrusion manufacturing base in Shanghai in 1999.
Executive Insights: The global demand for high-performance filaments, precision medical micro-tubes, and complex multi-layer automotive profiles is expanding rapidly. The convergence of additive manufacturing (3D printing monofilaments), high-speed telecommunication pipelines (silicone-core microducts), and medical-grade polymers requires extruder lines capable of maintaining sub-micron tolerances under high output demands.
Across advanced manufacturing markets in Europe, North America, and the Asia-Pacific region, filament and precision tube extrusion systems have transitioned from auxiliary tools to core components of high-end value chains. The rise of industrial FDM (Fused Deposition Modeling) 3D printing has forced manufacturers to move beyond simple PLA/ABS filaments. Modern facilities now require complex setups for engineering-grade materials like PEEK, PEI (Ultem), Carbon-Fiber reinforced Nylons (PA), and PVDF.
Additionally, the medical device sector depends on precision multi-lumen tubing for minimally invasive surgeries. These tubes require strict dimensional tolerances (ovality and wall thickness deviations below ±0.02mm). Similarly, the automotive industry needs multi-layer PA smooth/corrugated hoses for fuel, vacuum, and thermal management systems to meet strict environmental compliance rules.
| Polymer Type | Common Applications | Extrusion Temp Range | Tolerance Requirements | Crucial Extruder Line Feature |
|---|---|---|---|---|
| PA (Nylon 11/12) | Automotive fuel lines, pneumatic tubing | 220°C - 280°C | ±0.05 mm | Vacuum sizing calibration table, high-torque screw design |
| PEEK / PEI | High-temp 3D printing filaments, aerospace conduits | 360°C - 420°C | ±0.03 mm | Ceramic heater bands, high-temperature alloy screws |
| Silicone + HDPE | Fiber-optic micro-duct lines | 190°C - 230°C | ±0.10 mm | Co-extrusion cross-head feed block, dual puller systems |
| Medical Grade PVC/PUR | Multi-lumen catheters, IV drip tubes | 160°C - 200°C | ±0.015 mm | Cleanroom air support, ultra-precise melt pump systems |
Understanding how these products work in different regions helps factories set up custom machinery for their specific operating environments:
Typically used inside Class 10,000 cleanrooms. Systems feature medical-grade stainless steel vacuum cooling tanks, high-speed pullers, and precise cutting assemblies like the FQ Series Rotary Fly Knife Cutter to prevent tube deformation during production.
These systems must handle multi-layer configurations (such as PA/EVOH/PA) to prevent fuel vapor leakage. Incorporating our Multi-Layer PA Smooth/Corrugated Hose Extrusion Lines ensures layers adhere properly and the hose structure is uniform.
These applications require high line speeds to manufacture HDPE tubes with a thin, friction-reducing inner silicone layer. Precision tooling inside the crosshead die ensures the silicone layer is distributed evenly along the inner wall.
Engineered for high-stability manufacturing of tiny, thin-walled tubing used in pneumatic applications, consumer electronics, and general industrial lines. Featuring specialized die tooling for minimal thickness variation.
Designed for manufacturing composite fuel lines and thermal conduits. Delivers precise control over multiple melt streams, allowing different functional polymers to bond together effectively.
An ultra-precise, high-output production line built for medical manufacturing environments. Fully integrated with laser diameter control and specialized cutting systems to maintain strict quality standards.
Equipped with a high-speed mold block chain system for forming corrugated patterns. This line is widely used for producing automotive cable harnesses, medical breathing tubes, and electrical conduits.
Incorporates a precision reinforcement fiber knitting station within the co-extrusion line. Perfect for high-pressure cooling hoses and mechanical applications requiring structural reinforcement.
A specialized profile system built for manufacturing automotive door and window sealing strips. Supports single-extrusion, co-extrusion, and metal-insert insertion in a single, automated line.
