Precision investment casting is also called lost wax casting. Its products are precise, complex and close to the final shape of the part. It can be used directly without machining or processing. It is an advanced process of near net formation.
It uses a suitable investment material (such as paraffin) to make the investment mold; repeats the refractory coating and refractory sand process on the investment mold, hardens the shell and dries; then melts the internal melting mold to obtain the cavity; roasting type to obtained the shell with sufficient strength and the residual investment material burned off. The metal material required for casting is poured, the solidification is cooled, and the sand is removed after shelling to obtain a high-precision finished product.
