Single-Screw Extruder

Single-screw extruders are extrusion machines widely used in plastic processing, known for their cost-effectiveness, heavy-duty structural stability, and easy operation with minimal maintenance. They are ideal for general-purpose extrusion where consistent output and cost efficiency matter most.

Vented Single-Screw Extruder for PC and PMMA

Suitable for clear materials such as PC and PMMA, especially when producing optical-grade or decorative sheets that have strict requirements regarding surface and transparency. During extrusion, the venting section removes trapped gases and moisture, which helps prevent bubbles and improve the appearance of the finished sheet.

Please let us know the material you plan to process and the output you require. Our engineers will then recommend a suitable extruder configuration to improve production stability, thickness consistency and product clarity.

Working Principle

Plastic resin enters through the feed section and moves into the heated barrel. The rotating screw moves the material forward while it is gradually heated, melted and mixed into a uniform melt. Then, the molten resin passes through the die, which forms it into a continuous sheet, board or profile with the required dimensions.
