Mold polishing is usually the use of whetstone, sandpaper, polishing paste, wool wheel, etc., the mold cavity surface grinding, so that the work surface of the mold (die casting mould supplier china) can be bright as a mirror process, known as the die grinding.

mechanical polishing

Mechanical polishing by cutting, surface plastic deformation was removed after polishing and convex smooth surface polishing method, the general use of oilstone, wool wheel, sand paper, mainly manual, special parts such as rotary table surface, can use auxiliary tools such as high surface quality requirements can be used method ultra precision polishing.

chemical polishing

Chemical polishing is to make the material in the chemical medium surface micro protruding part, concave part of priority dissolved, so as to obtain smooth surface. The main advantage of this method is that the complex parts can be polished without complicated equipment, and many workpieces can be polished at the same time, and the efficiency is high. The key problem of chemical polishing is the preparation of polishing liquid.

Ultrasonic polishing
The workpiece is placed in an abrasive suspension and is placed together in an ultrasonic field, depending on the oscillating action of an ultrasonic wave to grind the abrasive on the surface of the workpiece. Based on the solution of corrosion, electrolysis, and ultrasonic vibration mixing solution, dissolving the product from the surface of the workpiece, near the surface of the electrolyte corrosion or uniform; ultrasonic cavitation in the liquid can also inhibit the corrosion process for surface light lighting.
