A primer on casting: A casting is a molded part for which the mold is often made of sand. This mold is created by packing the sand around a pattern. While the mold is a negative of the cast part, the pattern is a negative of this mold. Therefore, the pattern—a negative of a negative—is a direct geometric model of the final component.
Mold-making – The first step in the sand casting process is to create the mold for the casting. In an expendable mold process, this step must be performed for each casting. A sand mold is formed by packing sand into each half of the mold. The sand is packed around the pattern, which is a replica of the external shape of the casting. When the pattern is removed, the cavity that will form the
Treated sand is molded around a wood or meta pattern. The mold halves are opened and the pattern is removed. Metal is poured into the cavity. The mold is broken and the casting is removed Ounces up to tons ± .03″ to 6″ then add ±.003″/inch Add ±.020″ to .090″ across parting line 200-550 RMS 1 to 5 degrees .25″ All 00 to 000 Samples: 2 to 6 weeks Production: 2 to 6 weeks V-PROCESS

A primer on casting: A casting is a molded part for which the mold is often made of sand. This mold is created by packing the sand around a pattern. While the mold is a negative of the cast part, the pattern is a negative of this mold. Therefore, the pattern—a negative of a negative—is a direct geometric model of the final component.
