Each machine is capable of making 350-400 molds an hour. Once the sand mold is created and the molten iron hits the right temperature, we pour the liquified metal into the mold. Since sand melts at a higher temperature than iron, the mold holds its shape. When the cast iron has cooled, the castings move along a vibratory conveyor to shake off ...

The sand mold is usually done in two halves, where one side of the mold is made with one pattern and another side is made using the other pattern (shown in Figure 1). While the molds may not always be in two halves, this arrangement provides the easiest method of both creating the mold and accessing the part, once cast.

Also known as abrasive blasting, sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It's called "sandblasting" because it blasts the surface with particles of sand.
