Routine operation of precision casting

Precision casting is a casting method compared to the traditional casting process. It can obtain relatively accurate shapes and high casting accuracy.

The more common method is to first make the electrode of the required blank (with very small margin or no margin), and then use the electrode to corrode the mold body to form a cavity. Then use the casting method to cast wax to obtain the original wax mold.

Brush the wax pattern with high temperature resistant liquid sand layer by layer. After obtaining sufficient thickness, dry it, and then heat it to melt the wax mold inside to obtain a cavity consistent with the required blank. Then cast molten iron in the cavity, and peel off the shell after solidification to obtain a precision-manufactured finished product.
