WHAT IS CASTING

The development trend of casting products is to require castings with better comprehensive performance, higher precision, less margin and smoother surface. In addition, the requirements for energy conservation and the society's call for restoration of the natural environment are also increasing. In order to meet these requirements, new casting alloys will be developed, and new smelting processes and new equipment will appear accordingly... The casting process can be divided into three basic parts, namely casting metal preparation, mold preparation and casting processing. Casting metal refers to the metal material used for casting castings in the production of casting. It is an alloy composed of a metal element as the main component and added with other metals or non-metal elements. It is customarily called a casting alloy, mainly including cast iron, Cast steel and cast non-ferrous alloys... Casting is a kind of metal thermal processing technology that mankind has mastered relatively..
