Extrusion Feed Screws

ZY Screw supplies high-performance Extrusion Feed Screws specially designed for the feeding section of twin-screw extruders.
The extruder adopts a starve-feeding design, and the feed screw elements are configured with long, open flights according to the material form (powder, granules, or flakes) to ensure stable and uniform conveying into the melting zone. The feeding rate is independently controlled by the screw speed, allowing precise process adjustment and consistent output.

Customized feed screws can be manufactured from high wear-resistant or corrosion-resistant materials such as stainless steel to meet hygiene requirements in food and medical industries, as well as enhanced corrosion resistance for marine and chemical environments.

Optimized open-flight geometry for smooth and stable material intake

Professional material selection for wear, corrosion, or hygiene-critical applications

Manufactured strictly according to OEM specifications for perfect compatibility

Advanced CNC machining and CAD/CAM systems ensuring tight tolerances and excellent surface finish

Long service life under abrasive and high-load feeding conditions
