Which parts are suitable for precision casting?

In fact, investment casting is widely used, but considering size, weight and cost, it is now used selectively. Precision casting has the advantages of a wide range of materials, small casting precision tolerances, and high surface smoothness. Assemblies can be produced in one go, Suitable for mass production. The disadvantages are long production cycle, high auxiliary materials, limited size and weight of castings, strict process requirements and process management.

Including investment casting, ceramic casting, metal casting, pressure casting and disappearing casting. The most commonly used is investment casting: select the appropriate investment material to make the honing machine investment mold; repeat the coating and sandblasting process on the investment mold to harden the shell And dry; then dissolve the internal investment mold to obtain the cavity; bake the shell to obtain sufficient strength, burn the remaining investment material, pour the required metal materials, and remove the sand after the shell, thereby obtaining a high-precision finished product. According to Products require either heat treatment and cold processing.
