The dual-alloy screw is a screw made from two different alloy materials, typically featuring an outer layer of high-strength, wear-resistant alloy steel and an inner layer composed of a special alloy material that is highly corrosion-resistant and elastic. The dual-alloy screw combines the outer layer's high strength and wear resistance with the inner layer's high elasticity and corrosion resistance, and is widely used in plastic extruders, rubber extruders, and rubber molding machines.

Features of the Double Alloy Screw:

High wear resistance: The outer alloy steel has high hardness, offering good processing properties for plastics or rubber materials that require high wear resistance.

High Strength: The outer alloy steel features high strength and rigidity, suitable for extruders operating at high speeds over extended periods.

High Corrosion Resistance: The inner layer's special alloy boasts excellent corrosion resistance, effectively extending the service life of the screw.

High Elasticity: The high elasticity of the inner material ensures greater stability during the extrusion process, resulting in superior molding effects.

The main application fields of the dual-alloy screw are extrusion machinery, such as plastic extruders, rubber extruders, and rubber molding machines. Due to their high wear resistance, high strength, and excellent corrosion resistance, dual-alloy screws can meet the processing requirements of various materials, and are widely used in the production of various plastic and rubber products.
