Sand Core Making Sand Casting Core Harrison Castings
Core making is the process which forms the interior part of the casting. The mold provides a space for the molten metal to go, while the core keeps the metal from filling the entire space. Cores can be used to extend mold projections to create extra mold sections, or to block out and create negative drafts. Complex castings can involve the use

2020-4-21 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.
