Coatwell manufactures various types of bimetallic screw as per customer requirement. We offer bimetallic screw with different hard face armouring. We also offer fully encapsulated bimetallic screw for complete protection from glass filled polymers. Bimetallic screws can be electroplated for extra life.
Bimetallic barrels are made from 4140 or 4340 steel. Steel rods are drilled and bored to form a tube. The tube is filled with powdered metal and closed at ends. It is then heated in a furance. The heat melts the powdered metal. This melt is evenly distributed by rotation. It is cooled and machined to final internal dimension. It is then machined as per drawings and inspected before dispatch.
