Single-Screw Plastic Pelletizing Machines

Single-Screw Plastic Pelletizing Machines


In the ever-evolving landscape of plastic recycling, the Single-Screw Plastic Pelletizing Machines stand out as a state-of-the-art solution. These machines, equipped with Heat Wave Stabilization™ technology, offer uniform heat distribution, ensuring the production of high-quality plastic pellets. Whether you opt for a single or double-stage arrangement, these machines come standard with features that drive efficiency and reduce operational hiccups.

Working Principle

The core of these pelletizing machines is a high-precision gearbox that quietly yet steadily drives the screw shaft. This movement propels the molten plastic forward through the barrel. The barrel and screw shaft are crafted from specially blended steel, fortified with gas nitriding technology to resist corrosion and wear. Super mute blower fans along the barrel length provide centralized temperature control, ensuring optimal performance.
