The main solution for the design and actual production of iron mold sand covered casting process

① The thickness of the iron wall and the thickness of the sand layer, as well as their coordination, are used to meet the different requirements for solidification and cooling of castings with different wall thicknesses and materials;

② Convenient and economical sand covering molding method to meet the requirements of different castings for surface quality and dimensional accuracy;

③ Process parameters. Determination of pouring system, sand injection system, exhaust system, etc;

④ The implementation of mass production. For example, the design and finalization of production lines, sand covered main and auxiliary machines;

⑤ The formulation of process specifications, such as pouring, cooling, and unboxing procedures, as well as adjustments to the composition of castings.
