What parts are precision casting suitable for?

In fact, precision casting has a wide range of applications, but considering the size, weight and cost, it is now used selectively. The advantages of precision casting are a wide range of applicable materials, small casting precision tolerances, high surface smoothness, and the ability to produce combined workpieces 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.

These include investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting. The most commonly used one is investment casting: select the appropriate investment material to make the honing machine investment mold; repeat the painting and sandblasting process on the investment mold , harden the shell and dry; then dissolve the internal investment mold to obtain the cavity; bake the shell to obtain sufficient strength, burn off the remaining investment material, pour the required metal material, and clean the sand after shelling to obtain a high-precision finished product .According to product needs or heat treatment and cold processing.
