400kg/h Plastic Sheet Extrusion Machine for Roll Making

400kg/h Plastic Sheet Extrusion Machine Product Introduction 

The 400kg/h Plastic Sheet Extrusion Machine for Roll Making is a high-performance production line designed for manufacturing PP and PS plastic sheets in roll format. It is widely used in packaging, thermoforming, printing base sheets, and industrial material production.

The system includes a high-efficiency extruder, precision melt filtration, multi-zone temperature control, sheet die head, cooling calibration unit, and automatic winding system. It ensures uniform sheet thickness, excellent transparency or rigidity depending on material selection, and stable high-speed production.

With advanced screw geometry and optimized pressure control, the machine guarantees consistent melting and extrusion quality. The automatic winding system ensures smooth roll formation with adjustable tension control. This line is ideal for manufacturers requiring continuous, stable, and large-capacity sheet production.

Working Principle：

Plastic raw materials are fed into the extruder where they are melted and homogenized under controlled temperature and pressure. The molten material is pushed through a sheet die to form a uniform sheet, which is then cooled through a calibration unit. After stabilization, the sheet is automatically wound into rolls with controlled tension for consistent packaging output.
