Sand Casting

The basic technique of sand casting dates back thousands of years in time. Metal is melted and poured into a mold made of bound sand – an abundant material which is resistant to heat. After the molten metal is cooled, the sand mold is destroyed and a ‘casting’ is removed.
After the casting process, the sand molds are shaken away and excess gating and risers are sawed off for re-melting.
The parts are then ground clean with abrasives by experienced, well-trained personnel. A variety of finishes are also achieved by blasting the casting surface with different media including aluminum oxide, glass beads, or shot blast.
