Rust removal method for stainless steel precision castings

The dry treatment method refers to the friction treatment method dominated by shot blasting and rust removal to achieve the treatment of the surface layer of precision castings. The surface layer of precision castings, cleaning the surface of sand and iron oxide scale, etc., but this type of friction treatment has been selected by the manufacturers because of its low productivity, uneven treatment, and poor actual results. Eliminated. The core of the wet-type reasoning method is the electro-hydraulic hammer phenomenon. The high-voltage pulse generator realizes phase-to-phase discharge by means of a special electrode placed in water, forming a large hydraulic impact force. Because the adhesion of the surface layer of the precision casting is different from the ductility modulus and vibration frequency of the casting itself, the sand removal effect is achieved. It has a more effective processing effect for complex-shaped precision castings such as deep holes, blind holes, and inner walls. It is a surface treatment method for a series of castings including precision castings that are widely used at the present stage. The above are the common processing methods of the surface layer of the precision castings of the two. We must remind everyone here that the two methods of processing are not only for precision castings. A large part of the metal castings are processed in the process of forming. The surface layer must be treated. Yuankun Precision Casting is an indispensable process in the product of metal casting. For the treatment of the surface layer of the casting, the core meaning is to remove sand and iron oxide on the surface of the metal casting. The series of impurities make the surface of precision castings have a stainless steel casting metallic luster, which meets the standards of product implementation. Therefore, the surface treatment of precision castings is critical. Everyone should deal with the surface of precision castings according to the correct way. . In order to ensure the quality of precision casting products.
