Three polishing methods of precision stamping mould

 Thereare two main purposes for polishing precision stamping mould. One is to increase the brightnessand beauty of precision moulds. The second is to facilitate demoulding.

1.Mechanicalpolishing:It is a polishing method to get a smoothsurface by cutting and plastic deformation of material surface to remove theconvex part after polishing.

2.Electrolyticpolishing:The surface is smooth by selectivelydissolving small projections on the surface of the material.

is put into the abrasive suspension and placed in the ultrasonicfield together. The abrasive is grinded and polished on the workpiece surfaceby the oscillation of the ultrasonic wave.
