In the process of designing, the staff must fully consider the feasibility of grinding, grinding and polishing the cavity parts. This is because during machining, although its machining accuracy is theoretically well controlled, and its specific shrinkage rate is consistent with the expected result.

In the molding process of precision casting molds, certain deviations are still inevitable. This will inevitably affect its precision. In addition to these common measures, we also need to supplement corresponding positioning facilities to ensure accurate and reliable positioning accuracy.

In the process of selecting materials, attention should also be paid to selecting alloy tool steels with better mechanical properties. In addition, attention should be paid to testing other physical properties of the material to ensure that its hardness, wear resistance, corrosion resistance, etc. meet specific requirements. Not only that, but we also need to take into account the processability of these materials in the process of casting into precision casting molds.

Considering that in practical applications, due to the influence of temperature factors, a certain degree of expansion may occur, so while ensuring the use requirements of precision casting molds, a reasonable exhaust design is also required. In short, only by ensuring the rationality of precision casting mold design can we produce pig mold products with higher precision.
