Explore our engineering excellence through these standard-setting primary systems configured for diverse industrial applications.
The global manufacturing landscape is undergoing a massive transformation, driven by additive manufacturing (3D printing) and high-precision plastic extrusion. Today, the demand for Custom Plastic Filament Extrusion Machines extends far beyond basic plastic processing. Advanced sectors including aerospace, automotive, medical instrumentation, and consumer electronics now require structural and high-temperature filaments with strict tolerance limits of ±0.02 mm.
Industrial polymer filaments such as PLA, ABS, PETG, TPU, and high-performance engineering plastics like PEEK, PEI (Ultem), and PPSU demand sophisticated extrusion control systems. Achieving structural uniformity in these filaments requires precise control over thermal degradation, melt flow index (MFI), and volumetric expansion. As a leading manufacturer, we develop machines designed to process diverse rheological compounds, converting raw polymer pellets into high-grade industrial filaments.
High-precision filament extrusion plays a critical role in modern production workflows:
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, dedicated to designing, manufacturing and sales of plastic extrusion equipment. Based on 18 years experience of designing and fabricating high quality machines in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing extrusion machines manufacturing base in Shanghai in 1999.
Over the decades, we have continuously refined our technical capabilities. Our long-term research and development focuses on:
Ultra-precise dimension and tolerance management for high-precision plastic products.
Optimized screw geometries and thermal zones that lower energy use while maximizing output.
Integrated Siemens PLC architecture for smart diagnostics and centralized operations.
CE and UL compliant safety relays, thermal protection, and automated shutdown systems.
Operating from our 16,000 square meter factory in Jiangsu, BAOD combines advanced manufacturing technology with efficient supply chain management. This allows us to deliver high-performance extrusion lines that match European precision standards while remaining cost-effective.
Our China-based factory improves efficiency through key structural advantages:
To manufacture high-quality 3D printing filament or engineering monofilament, an extrusion system must maintain consistent material flow and dimensional stability. Variations in melt pressure, temperature, or puller tension can lead to diameter inconsistencies, causing printing failures or structural weaknesses.
We design bimetallic screws configured for specific polymers. For PLA/ABS, we utilize a barrier design with a high L/D (Length/Diameter) ratio to ensure uniform melting without thermal degradation. For high-temperature materials like PEEK, we use wear-resistant alloys that handle temperatures up to 450°C.
Our extrusion lines feature a high-precision gear melt pump positioned between the extruder and the die head. This pump regulates polymer flow, eliminating pulsation and maintaining consistent head pressure to achieve precise filament sizing.
Our cooling systems utilize multi-stage water baths with automated temperature regulation. Keeping the cooling water temperature stable is essential to control the crystallization rate of semi-crystalline polymers, preventing filament warping and ensuring roundness.
Our systems integrate dual-axis laser diameter gauges that measure filament size in real-time. If the diameter deviates from the set value, the PLC automatically adjusts the puller speed to bring the filament back within spec.
In addition to standard filament systems, we manufacture specialized extrusion lines for automotive, medical, and industrial applications:

Our precision medical tubing and high-grade 3D filament extrusion lines achieve tolerances down to ±0.02 mm. This stability is maintained using melt pumps, precise puller speed synchronization, and real-time laser measurement systems with closed-loop feedback.
We build machinery for a wide range of materials, including commodity plastics (PE, PP, PVC), engineering elastomers (TPV, TPU, PA), and high-temperature polymers (PEEK, PEI, fluoropolymers). We customize the screw design, barrel heating zones, and die metallurgy based on the specific material processed.
A dual-axis laser gauge continuously measures the outer diameter and roundness of the extruded profile as it exits the cooling bath. The gauge transmits this data back to the Siemens PLC. If deviation occurs, the control system adjusts the haul-off puller speed or the melt pump rate to keep dimensions within spec.
Yes. All BAOD extrusion equipment is designed to comply with CE safety regulations. We source key electrical and control components from trusted global suppliers like Siemens, ABB, Schneider, and Omron to ensure ease of maintenance and safety compliance worldwide.
Lead times depend on configuration complexity. A standard single-layer line typically takes 60 to 90 days, while complex co-extrusion lines or custom medical lines can take 90 to 120 days. This timeline allows for engineering, assembly, and testing before delivery.
