How to Make a Sand Casting. Sand casting involves four basic steps: assemble the sand mold, pour liquid metal into the mold, allow the metal to cool, then break away the sand and remove the casting. Of course, the process is more complex than it sounds. The first step of mold assembly is to partially fill the drag with sand. The pattern, core print, cores, and gating system are placed near the ...

If the shear strength of the sand is below that of the pressure created by the liquid metal filling the mold, the core might split and create a distortion in the casting body. Binders are a big part of the core-sand making process. Green sand cores are made from standard damp molding-sand mixtures, and a binder, like dextrin. Cores of this type ...
