Working Process

1. Material Feeding
Plastic raw materials, additives, fillers, or polymer blends are supplied into the extruder through the feeding system.

2. Material Conveying
Twin screws rotate continuously to transport materials forward while improving mixing performance.

3. Melting and Mixing
Controlled heating and screw shearing force melt and uniformly mix the materials.

4. Extrusion Forming
The molten material passes through the extrusion die to form continuous strands or shaped products.

5. Cooling and Solidification
Extruded materials are cooled to achieve stable shape and physical properties.

6. Pelletizing Process
The cooled strands are cut into uniform pellets for storage, testing, or further processing.
