Product Details

Plastic granulator screw, also known as an extruder screw, is a crucial component in the plastic recycling and manufacturing process. It plays a vital role in transforming plastic materials into granules or pellets that can be used to produce various plastic products.The plastic granulator screw consists of a cylindrical shaft with a helical ridge, known as the screw flight, wrapped around it. This design enables the screw to transport, compress, melt, and mix plastic materials as they pass through the screw barrel. The barrel typically has several heating zones to control the temperature along the screw’s length, ensuring proper melting and processing of the plastic.

Screw element material are W6Mo5Cr4V2,38CrMoAI ,wp5.high temperature vacuum quench treatment;hardness HRC ≥ 62,Tolerance: ±0.001mm~±0.01mm,Screw element is made by the surface forming grinding through machining center.
The Mixing function is used for twin-screw extruders, twin-screw plastic pelletizers, and twin-screw compounding pelletizers.Mixing function material are W6Mo5Cr4V2,38CrMoAI ,wp5.high temperature vacuum quench treatment;hardness HRC ≥ 62,Tolerance: ±0.001mm~±0.01mm,The Mixing function angles are 30, 45, 60, and 90 degrees, and other angles can be customized. Mixing function is made by the surface forming grinding through machining center.
The screw shaft is made of high toughness, high flexural strength, and high-quality alloy steel 40CrNiMoA .
