Carbide coating to prevent slippage in bending operations

Seuthe Tube Welding and Section Lines

An application of Carbinite coating can tighten machinery’s grip on material during bending operations. When applied to the gripper arm in the holding area of mandrel or rotary draw systems the textured coating is said to prevent material from slipping or rolling during bending. Carbinite is a

carbide coating that iselectrofused to a base metal to add texture. This texture increases the coefficient of friction between the clamping surface and the workpiece allowing for a strong, solid grip

in the holding and clamping areas of the tube bending process. Carbinite is applied by electrofusion, resulting in an incredibly strong bond since the carbide is fused into the base metal, not just applied onto it as in spray welds. Bulk heating is not required, so tool temper and heat treat are not affected. If needed, it can be applied and reapplied without stripping away existing layers. If a metal tube or pipe requires a sequence of bends, an application in the gripper area of a seeker or plainer will help ensure that when the dye rotates around and the arm comes in contact with the material, slippage does not occur. This prevents the material from being knocked out of plane.
