Dimensional Tolerances in Investment Castings

[JacksonT]

Hi everyone, I'm exploring investment casting for a project and wondering about the dimensional tolerances I can expect. Can anyone provide some insights into this?

Hey there! Dimensional tolerances in investment casting can vary depending on factors such as the complexity of the part, the material being used, and the capabilities of the foundry. Generally, investment casting can achieve tolerances of ±0. 005 inches per inch for the first inch and ±0. 002 inches per inch for each additional inch.

That's good to know! Are there any factors that might affect the dimensional accuracy of investment castings?

[Elliott]

Absolutely. Factors such as shrinkage during cooling, mold distortion, and variations in the casting process can all influence dimensional tolerances. It's essential to work closely with your foundry and consider these factors during the design phase to ensure the desired tolerances are achievable.

Thanks for the information! It sounds like close collaboration with the foundry is key to achieving accurate dimensional tolerances.
