Product Description:

The Four-head kneading block extrusion screw elements are precision-engineered components designed for twin screw extruders, specifically in the melting and mixing zones. Featuring a unique four-lobe geometry, these elements generate intensive shear and distributive mixing, making them ideal for processing engineering plastics, color masterbatch, and filled compounds. Manufactured from high-speed tool steel or HIP alloy, each element undergoes CNC machining and vacuum heat treatment to ensure excellent wear resistance, thermal stability, and long service life. Customizable angles (30°, 45°, 60°) and spline configurations are available to match various extruder brands and specific compounding requirements.
