Sand Casting Explained
Molding is the multistep process in which molds are created. In horizontal casting, the mold is contained in a two piece frame, called a flask. The upper portion of the flask is called a cope and the lower portion is a drag. First, molding sand is packed into a flask around the pattern. After the pattern is removed, gating and runner arrangements are positioned in the drag half of the mold ...

Sand and hardening methods in sand casting process ...
· The chemical hardening in sand casting is mainly for: 1）Selfhardening: 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.
