Technical Field

[0002] Metal casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold, and then cooling and solidifying it to obtain a casting with a predetermined shape, size and performance. Forging production has the advantages of saving metal, high production efficiency, and great flexibility. Forging can compact the looseness and pores in the casting structure, break the coarse casting structure into fine grains, and form a fibrous structure. When the fibrous structure is reasonably distributed along the contour of the part, it can improve the mechanical properties of the part. Because the casting blank is almost formed, it can achieve the purpose of no mechanical processing or a small amount of processing, which reduces costs and reduces time to a certain extent. Casting is one of the basic processes of the modern machinery manufacturing industry, and polishing devices may be used in most metal castings.
