Polishing Perfection: The Craft of Die-Cast Excellence
Factory Process: Polishing
In addition to simple mechanical polishing, there are a variety of precision polishing techniques to meet different needs.
Chemical polishing, for example, smoothes surfaces through the selective dissolving action of a chemical solution, and is particularly suited to complex shaped workpieces;
Electropolishing, on the other hand, utilizes electrochemical principles to selectively remove the surface of a material by means of an electric current in order to obtain a highly uniform and bright surface;
Ultrasonic polishing combines ultrasonic vibration with abrasive particles and is suitable for polishing fine and complex structures;
Laser polishing utilizes a high-energy laser beam to melt and reshape the material surface for non-contact precision polishing;
Magnetic polishing drives abrasive particles across the surface of the workpiece by means of a magnetic field, and is suitable for small and complex shaped workpieces;
and steam polishing, which slightly melts the surface of the workpiece by means of solvent vapors, filling defects and creating a smooth surface, especially for thermoplastics.
The polishing method in the picture above is mirror polishing. Mirror polishing is a special polishing process designed to achieve a mirror-like surface with a high degree of smoothness and reflectivity, which is the polishing method chosen by many customers.
