Our standard material is a 4-sieve distribution. This means that 4 sieves contain more than 10% retained. Our current material has more than 90% on the ASTM 40-100 sieves. A typical sieve distribution is shown below.

This has been shown through research to provide an excellent packing density which reduces the binder requirements and improves casting quality.

Our new processing plant will allow us to provide a range of different distributions and sizings according to individual foundry’s requirements.
