Investment casting is an excellent choice for applications that call for more accurate precision cast parts. It has the capability to meet vital size specifications and consistency requirements over long runs of parts. In addition to utilizing the right process, the foundry must have expert professionals who can ensure that the castings are correctly planned and produces. For example, molten alloys shrink as they cool in the molds, making the final dimensions of the castings smaller than the molds. This must be taken into account during mold design. The almost endless variety of alloys increases the complexity because each alloy requires its own shrinkage allowances. Surface finishing, if needed, can also alter the finished size of the parts.
