Tungsten carbide dies and plugs, tungsten carbide extrusion dies and mandrels.Tungsten carbide diess and plugs is the important accessory of expansion tube process,which has been widely used in the production of heat exchangers and evaporators in the refrigeration industry.
The expansion of the copper pipe is based on the expansion force of the tungsten carbide plugs, which causes the plastic deformation of the copper pipe, so that the work process of expansion of the outer wall of the copper pipe after the expansion of the diameter is tight on the inner hole of the aluminum fin.
