Barrel Single/Twin Front & Rear Barrel

Barrel from Dia. 25 mm to 200 mm & Length upto 6000mm

Barrels processed with bimetallic alloy centifugal casting have many virtues, such as high hardness, stronger wear & corrosion resistance. Its general properties are three to five times more compared to the nitriding steel. They are wildly used for highly abrasive & corrosive materials like engineering polymers and pvc compounds. The bimetallic process used in world as advanced technology for better life with consistent production and quality. It is the best choice for  production special barrels. Like nitride bimetallic single & twin/ front & Rear bimettalic barrel.
