The following tabulation lists the tolerances recommended by the Investment Casting Institute. Nu-Cast is equipped to handle the demand of today's industry. Your specific configuration is an important criteria in determining dimensional variations from part to part. We will be pleased to consult with you on any tolerances or dimensions you may need that are not listed. As a general rule, a 0.03 maximum corner and a 0.06 minimum fillet are recommended.
Smaller radii are possible depending on the complexity of the design.
Flatness and straightness tolerances are .003 to .005 TIR per linear inch and depend on alloy properites and configuration of part. The general section thickness tolerances will prevail.
