What is foundry sand? - Solex

Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

Sand and hardening methods in sand casting process ...

The chemical hardening in sand casting is mainly for: 1)Self-hardening: when adding sand, add binder and hardener. In this way, the sand mold or core will harden by itself after it is made. 2)Gas mist hardening: no hardener is added during sand mixing. After modeling or core making, gaseous hardener or atomized liquid hardener is blown in.
