Bimetallic Barrel

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

Barrels processed with bimetallic alloy hardface coating have many virtues, such as high hardness, stronger wear & corrosion resistance. Its general properties are three to fifteen times more compared to the nitriding steel. They are wildly used for highly abrasive & corrosive materials like engineering polymers and pvc compounds. The main machining methods are as follows: spot spray, spray coating, cover coating, mould, butt welding etc. The bimetallic process used in world as advanced  technology  for  better  life with consistent production and quality. It is the best choice forproduction special screws. Polymers can be used : Minerals, Glassfibers, Pigment, Carbon fibers
