The goal of investment casting is to produce the part which would be near net shape as much as possible within the limitations of the process. To reduce this limitations design engineers need various information as well as design opportunities of casting process. Each casting application gets individual analysis and control of dimensional tolerance some of the generally accepted standards facilitate the faster manufacturing process as well as cost saving.

This is why we always emphasis various “definitions” in casting drawing. Which includes Material, Tolerance, Fillet and Corner Radii, Location and Amount of Machine Stock, Surface Finish and Casting Identification.

It is because the success of casing design heavily depends on the understanding between the designer and foundry engineers. When the requirements are clear the quality is what one can give result of.
