Foundry Sands
Silica, quartz, chromite, olivine and resin-coated shell sands used in mould and core making.
Moulding sand forms the main volume of the casting mould; sand type and grain distribution influence surface finish, metal penetration and mould strength. We supply silica, quartz, chromite, olivine and shell sands according to the metal to be poured and the casting requirements.
