Twin Screw And Barrel in Zhoushan For its excellent anti-erosion/corrosion and anti-abrasion characters, the bimetallic screws and barrels are widely used in the extrusion lines.With HVOF high speed spraying equipment,spray a layer of metal which melt on the screw surface; a melt-cast method is adopted to get bimetallic barrel,which could conform its precise formation. Specification: 45/90, 45/100, 50/105, 51/105, 55/110, 55/120, 58/124, 60/125, 65/120, 65/132, 68/143, 70/135, 70/140, 75/150, 80/143, 80/156, 92/188 The above are standard specifications, we can customize according to customers' requirements.
Screw structure and compression ratio can be designed according to different products and raw material.
