A simple explanation of the polishing method of Die Cast Aluminum Enclosures

Die Cast Aluminum Enclosures are rich in surface technology, polishing is only one of them, but it is an important process to improve the quality of Die Cast Aluminum Enclosures. Mastering a reasonable polishing method can improve the quality and performance of Die Cast Aluminum Enclosures, thereby improving the quality of aluminum alloy die-casting products.

About the polishing of Die Cast Aluminum Enclosures, in addition to conventional mechanical polishing and chemical polishing, there are also electrolytic polishing, ultrasonic polishing, fluid polishing, magnetic abrasive polishing, electric spark ultrasonic composite polishing and other technologies. Among them, the basic principle of electrolytic polishing of aluminum alloy die castings is the same as that of chemical polishing, mainly relying on the selective dissolution of the tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, it can eliminate the influence of cathode reaction, and the effect is better.

The ultrasonic polishing of Die Cast Aluminum Enclosures is a processing method in which the tool section is used for ultrasonic vibration, and the brittle and hard materials are polished by the abrasive suspension. Put the workpiece in the abrasive suspension and put it together in the ultrasonic field, relying on the oscillation effect of the ultrasonic, so that the abrasive is ground and polished on the surface of the workpiece.

The fluid polishing technology of Die Cast Aluminum Enclosures needs to rely on the flowing liquid and the abrasive particles carried by it to wash the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure. The medium is mainly made of special compounds with good flowability under lower pressure and mixed with abrasives. The abrasives can be made of silicon carbide powder.

Magnetic grinding and polishing is also one of the polishing technologies involved in Die Cast Aluminum Enclosures processing. Magnetic abrasives are used to form abrasive brushes under the action of a magnetic field to grind the workpiece. This method has high processing efficiency, good quality and easy control of processing conditions.
