Working Principle of PP/PS Sheet Extrusion System

The PP/PS sheet extrusion line operates through a continuous extrusion process. Plastic raw materials are melted and homogenized in the extrusion unit before being shaped into a continuous sheet through a precision flat die.

The main process includes:

1. Raw material feeding and mixing

2. Melting and plasticization in the extruder

3. Sheet formation through flat die system

4. Cooling and shaping via calendar unit

5. Thickness calibration and surface treatment

6. Automatic winding into finished rolls

The entire production process is controlled by a computerized system to ensure accurate control of thickness, width, and surface quality.

Multi-Layer Sheet Extrusion Capability

The PP/PS sheet extrusion line is capable of producing both single-layer and multi-layer sheets. Multi-layer co-extrusion technology allows different materials or functional layers to be combined in one sheet structure.

This enables:

• Functional barrier layers

• Recycled material core layers

• Transparent surface layers

• Color or decorative layers

Multi-layer design improves material performance while optimizing production cost efficiency.
