The compact structure, reliable operation and automatic control system help reduce labor costs, improve production efficiency and provide a practical solution for modern plastic granule manufacturing.

Industry Pain Points

Plastic manufacturers often face challenges such as unstable pellet quality, uneven material mixing, high energy consumption and complicated production processes. Traditional granulation methods may result in inconsistent particle sizes, excessive material waste and increased operating costs.

Our Solution

The Plastic Pelletizing Extrusion Line provides a complete solution by integrating efficient extrusion, precise temperature control, automatic pelletizing and cooling systems. It ensures uniform granule size, stable production performance and improved material utilization. The automated design reduces manual operation requirements while increasing productivity and production consistency.

Working Principle

1. Material Feeding

Plastic raw materials such as PVC, PE or recycled plastics are continuously fed into the extrusion system through the feeding hopper.

2. Plasticizing and Extrusion

The screw system heats, mixes and plasticizes the material under controlled temperature conditions, forming a uniform molten plastic flow.

3. Pelletizing Process

The extruded plastic strands are cut into small granules through the pelletizing unit to achieve consistent particle size.

4. Cooling and Conveying

The produced pellets are cooled and transported for collection, storage or further processing.
