INVESTMENT CASTING: TOLERANCE CAPABILITIES
Investment castings are designed to minimize the cost of producing close tolerance parts.
Typical tolerances listed on the chart below can be expected for production repeatability of all casting dimensions. Premium tolerances may require secondary operations that can impact cost and lead time.
Wall Thickness Tolerance – 0.01 ~ 0.015 (0.25mm ~ 0.375mm)
Angularity – 0.5° ~ 1°
Perpendicularity – 0. 008 / 1 (0.08mm / 10mm)
