Production And Manufacturing Of Investment Casting

The first process of investment casting production is to manufacture investment mold, investment is used to form a model of the cavity in the refractory shell, so to obtain castings with high dimensional accuracy and surface finish, first of all, the investment itself should have high dimensional accuracy and surface finish. In addition, the performance of the investment itself should also make the subsequent process of making the shell as simple as possible. In order to obtain the above high-quality requirements of the investment mold, in addition to good pressing (mold for pressing the investment mold), it is also necessary to select the appropriate mold material (referred to as mold material) and a reasonable mold making process.
