Our modular and precision-engineered screw elements break down the complex process into a series of highly efficient, controllable steps.
- 1. Precision Feeding
Metering systems ensure raw materials are fed accurately and consistently.
- 2. Conveying & Melting
Screw elements convey materials through heated zones for rapid, uniform melting.
- 3. Dispersive & Distributive Mixing
Specialized kneading blocks provide intense shear to perfectly disperse additives.
- 4. Homogenization & Devolatilization
Vacuum vents efficiently remove moisture and volatiles, enhancing pellet quality.
- 5. Pressurization & Extrusion
Stable pressure is built to extrude uniform strands of molten polymer through the die head.
- 6. Cooling & Pelletizing
Strands are cooled and cut by a high-speed pelletizer into consistently sized pellets.
