Bimetallic screw for injection moulding machine

A bimetallic screw and barrel for a rubber machine refers to the use of two different metals in the construction of the screw and barrel components. This design is commonly used in rubber processing machines to improve the durability and performance of the equipment.

The barrel is the cylindrical chamber through which the rubber material is fed and processed. It is typically made of two layers of metal - an outer layer made of a wear-resistant material such as alloy steel or tool steel, and an inner layer made of a high-temperature resistant material such as nitrided steel or bimetallic alloy. The use of two different metals helps to enhance the wear resistance and heat resistance of the barrel, ensuring a longer service life.

The screw is the rotating component that moves the rubber material through the barrel. Similar to the barrel, the screw is also made of two layers of metal. The outer layer is typically made of a wear-resistant material to withstand the abrasive nature of the rubber material, while the inner layer is made of a high-temperature resistant material to withstand the heat generated during the processing. This bimetallic construction helps to improve the screw's durability and performance.

Overall, the use of a bimetallic screw and barrel in a rubber machine provides several advantages, including improved wear resistance, enhanced heat resistance, and extended service life. This allows for more efficient and reliable rubber processing, resulting in higher productivity and cost savings for the machine operator.
