Mold Polishing Methods & How They Work

1. Mechanical Polishing

Mechanical polishing is a method that removes the protruding parts on the surface of a workpiece by cutting or plastically deforming the surface of a material to obtain a smooth surface.Mechanical polishing is the main method of mold polishing.

2. Chemical Polishing

Chemical polishing refers to the process in which a material is soaked in a chemical medium that allows the micro projections on the material surface to firstly dissolve before the dents, thus obtaining a smooth surface. The method can be applied to polish a workpiece with a complicated shape, and is able to concurrently work on many workpieces to achieve a high efficiency.

3. Electropolishing

The basic principle of electropolishing is the same as chemical polishing, which is to selectively dissolve the surface of a material to create a smooth surface. Compared with chemical polishing, it can eliminate the influence of the cathode reaction, thus producing a great effect.

4.Ultrasonic Polishing

Ultrasonic polishing is a method that uses a tool section for ultrasonic vibration to polish a brittle hard material by using an abrasive suspension. A workpiece is soaked in an abrasive suspension, and then placed in an ultrasonic field together with the suspension that grinds and polishes the surface of the workpiece by the action of ultrasonic waves.

5. Fluid Polishing

Fluid polishing relies on a flowing liquid and the abrasive particles it carries to erode the surface of a workpiece for polishing purposes.

6. Magnetic Grinding & Polishing

Magnetic grinding & polishing is the use of magnetic abrasives to form an abrasive brush under the action of a magnetic field to grind a workpiece. This method features a high processing efficiency, great quality and easy-to-control processing conditions.
