            Class cleanup method is to dry blasting process-oriented approach to the friction surface to clean stainless steel castings, shot blasting process simply is powered by compressed air, so that the projectile to a certain speed jet to the surface of stainless steel castings, to remove surface dip sand and iron oxide, etc., but this friction due to the low efficiency of the cleaning method, cleaning uneven, the effect was poor, has been the public were created by the factory, it has almost been eliminated.
            Reason Law wet type is mainly electro-hydraulic hammer effect principle, the high voltage pulse generator and white discharge through special electrodes placed in the water, resulting in a large hydraulic shock. Since the stainless steel castings and casting surface adhesion was itself an elastic modulus and vibration frequencies different to achieve the purpose of sand. Stainless steel castings for complex shapes such as deep, blind holes, the cavity has a more effective cleaning effect. It is currently the most widely used as a stainless steel castings, including a series of casting surface cleaning mode.
            These are two common methods to clean the surface of stainless steel castings, where the need to remind everyone that this is not just for the two stainless steel castings cleaning method, the vast majority of metal casting products after the molding process requires surface clean, metal casting products indispensable a process for cleaning up the casting surface, the most important role is in addition to stick sand and metal casting surface oxide scale and a series of impurities, so that the surface of stainless steel castings made of stainless steel metal luster, to the implementation of standard products, so surface cleaning stainless steel castings is very important, it must be in the correct way to clean stainless steel surface of the casting time.
