Introduction:

Investment casting technology is a casting technology widely adopted among the investment casting manufacturers and it can also be called precision investment casting. The biggest advantage of investment casting lies in that as the investment casting has relatively high dimensional precision and surface smoothness, mechanical processing can be reduced.

Areas of application:

However, as the technical process of investment casting is complicated, there are many factors influencing the dimensional precision of the castings, such as shrink of the pattern material, deformation of the mold, linear change of the shell in the heating and cooling process, shrinking percentage of the alloy and the deformation of the casting in the solidification process. For this reason, even though the dimensional precision of the common investment casting is high, but the uniformity remains improving.
