A rubber screw is a type of screw used in extruders for processing rubber and other elastomeric materials. The rubber screw is specially designed with a shallow helix angle and a deep root diameter to provide a greater surface area for the material to pass through.
The extruder is a machine used in the manufacturing process for melting and mixing materials such as rubber or plastic, and forcing them through a die to create a specific shape. The rubber screw is an essential component of the extruder, as it helps to process the material by creating heat and pressure within the extruder barrel.
Rubber screws are made from high-strength materials such as nitrided steel or bimetallic alloys to withstand the high temperatures and pressures generated during the extrusion process. They are also designed to be highly durable and resistant to wear, as the material passing through them can be highly abrasive.
In summary, a rubber screw is a specialized screw used in extruders for processing rubber and other elastomeric materials, providing greater surface area for the material to pass through and creating heat and pressure to aid in the extrusion process.
