Investment Casting Advantages
Maintaining close dimensional tolerance in an investment casting is affected by many factors. Most of these factors can be controlled by the foundry, although minor "lot to lot" variations will occur. The tolerance bands provided for investment castings are determined by these uncontrollable factors.
While careful machining can achieve closer tolerances than available in an investment casting, a critical design view will often permit minor expansion of tolerances, undercuts, blind holes, etc. to allow the higher production yields and lower piece costs possible with investment castings. If closer than cast tolerances are necessary, the machining required on an investment casting will still be substantially less than on conventional cast or fabricated pieces.
