Do you know why the appearance of home appliance molds is so smooth? In fact, this is because the surface of home appliance molds can be so smooth after the polishing process.

1. Ultrasonic polishing

Put the home appliance mold into the abrasive suspension and put it together in the ultrasonic field. Relying on the oscillation of ultrasonic waves, the abrasive is ground and polished on the surface of the home appliance mold. The macro force of ultrasonic processing is relatively small, and the home appliance mold will not be deformed. It is difficult to make and install the mold. Ultrasonic processing can be combined with chemical or electrochemical methods. In the conditions of solution electrolysis and corrosion, ultrasonic vibration is used to stir the solution, so that the dissolved products on the surface of the home appliance mold are separated, and the corrosion and electrolyte around the surface are uniform. Ultrasonic vibration Cavitation in the liquid can also suppress the corrosion process and facilitate the brightening of the surface.

2. Chemical polishing

Chemical polishing means the smooth surface obtained by dissolving the microscopically protruding part of the surface of the home appliance mold in the chemical medium for the first time to obtain a smooth surface. It can polish many home appliance molds at the same time, with high efficiency. The main problem of chemical polishing is the modulation of polishing liquid.

The above are the most commonly used polishing methods for home appliance molds, and they are also the most widely used polishing methods at present.
