Surface cleaning of stainless steel precision casting products

1. Dry cleaning of stainless steel precision casting.
Dry cleaning is divided into friction cleaning and shot peening. The friction cleaning efficiency is low and the effect is poor. Dry cleaning generally refers to shot blasting and shot blasting cleaning. Shot blasting uses compressed air as power to quickly spray steel shots to the surface of the workpiece to remove debris on the casting. Shot blasting is a more flexible method of shot blasting. Shot blasting uses a shot blasting mechanism to blast the steel shot and remove impurities on the surface of the casting.
2. Wet cleaning of stainless steel precision casting.
Electro-hydraulic sand cleaning refers to cleaning the shell under the action of voltage. Its basic principle is the electro-hydraulic hammer effect, which uses high-voltage pulse discharge to pass through special electrodes in the water to generate huge liquid energy. Because the vibration frequency of the surface debris of the precision casting is different from that of the metal, the purpose of sand removal can be achieved.
