What dimensional tolerances can we expect from investment casting?

Exceptionally close dimensional tolerances can be produced in a wide range of alloys. Part size and design complexity are the determining factors, but a linear tolerance of +/- .005 inches, (.127mm) per inch is common in investment casting. Generally, a tighter dimensional tolerance can be realized in a smaller part. Top

Are there limits to part sizes that investment casting produces?

At Shelmet, our precision casting process is virtually unlimited by part size, producing parts that weigh less than an ounce to those with weights upwards of 10+ pounds. It is quite common for us to produce we parts weighing as little as a few ounces. Top

Does investment casting require a certain type of tooling or pattern equipment?

We manufacture a split negative-cavity aluminum die that is then used to create the wax models. Based on the complexity of the design, soluble wax cores and ceramic inserts may also be used to produce the desired result. Top
