When To Use Investment Casting

• ●External shaping and tight tolerances exist

• ●Parts are shaped or non-symmetrical with fine detail

• ●Multiple and/or intricate internal passageways in design

• ●Dimensions are small to medium, typically under 1,000 lbs./454 kg

• ●Excellent as-cast surface finish is required

• ●Thickness is too thin for sand casting

• ●High upfront tooling costs relative to sand casting are acceptable

• ●Low volume allows printed patterns to replace upfront tooling

• ●Ongoing tool maintenance costs are not desired

• ●Machining of internal passageways is not possible
