Precision Lost Wax Investment Casting

Precision Lost Wax Investment Casting
Product Details


The first step in investment casting production is to make a investment mold. The investment mold is used to form a cavity in the refractory shell. Therefore, in order to obtain a casting with high dimensional accuracy and high surface finish, the first mold itself should have a high size. Precision and surface finish. In addition, the performance of the investment mold itself should be as simple as possible for the subsequent process of forming the shell. In order to obtain the above-mentioned high-quality investment, in addition to a good press type (die for pressing the mold), it is necessary to select a suitable molding material (referred to as a molding material) and a reasonable molding process.

When the investment mold is pressed, the molding having a high surface finish of the cavity is used, and therefore, the surface finish of the investment mold is also relatively high. In addition, the shell is made of a refractory paint made of a special binder and a refractory material which is resistant to high temperature, and is coated on the investment mold, and the inner surface of the cavity which is in direct contact with the molten metal has a high surface finish. Therefore, the surface finish of the investment casting is higher than that of the general casting, and generally reaches Ra.1.6~3.2μm.
