China Mini Plastic Extrusion Machine Manufacturers & Factory

A mini plastic extrusion line typically utilizes screw diameters ranging from Ø12 mm to Ø30 mm with volumetric outputs between 0.2 kg/h to 15 kg/h. These systems are specifically designed for processing expensive engineering polymers (PEEK, fluoropolymers, medical polyurethanes) or micro-tubes with outer diameters ranging from 0.2 mm to 10 mm. The emphasis is entirely on micro-melt stability, minimal barrel residence times to prevent polymer degradation, and closed-loop tolerance control (±0.01 mm or tighter).

Through 25+ years of engineering evolution and Taiwan-origin technical heritage, manufacturers like BAOD utilize the same tier-1 international motion control components (Siemens PLC, Schneider electronics, Dynisco melt transducers, Zumbach/Beta laser gauges). The true differentiator lies in custom screw/die design and total cost of ownership: Chinese manufacturers offer comparable dimensional precision, reduced spare part lead times, and significantly lower capital expense, with pre-delivery Factory Acceptance Tests (FAT) using the buyer's actual resin formulations.

Yes. For extreme thermal applications (up to 420°C), our machines are configured with specially treated barrels made from Hastelloy, Inconel, or GH113 bimetallic alloys, high-watt-density ceramic heaters, and specialized cooling jackets. Furthermore, we implement customized screw profiles that maintain laminar, low-shear flow without stagnating heat-sensitive fluoropolymers.

To provide an accurate technical proposal and line layout, our engineering team requires: (1) Product dimensional drawings including nominal OD, ID, wall thickness, and tolerance bands; (2) Raw resin specification sheet (melt flow index, specific gravity, brand/grade); (3) Target linear line speed or output rate in kg/h; (4) Multi-layer configuration requirements (if applicable); and (5) Local factory utility details (voltage, phase, hertz, compressed air, and cooling water specifications).

For micro-bore medical and technical tubing, we integrate precision stainless-steel vacuum calibration tanks with multi-zone closed-loop water temperature control, servo-driven high-speed belt pullers (such as our TKB/QYP series) that eliminate micro-vibrations, non-contact dual-axis laser measurement systems, and ultra-high-speed rotary fly knife cutters (FQ series) capable of up to 1,500 cuts per minute with completely clean, burr-free end faces.
