The shell molding (or shell casting) process is the industry standard for medium to high volume, commercial grade casting projects. This animation offers a better look at how the process works.
In this process, thermally bonded sand is applied to the surface of a pre-heated pattern usually made of cast iron or steel. The “baked” mold is lifted from the pattern in halves. The halves are glued together and pressed into a mold.
The shell molding process offers tolerances of +/-.030” on dimensions 6” or less and a surface finish around 200 - 250 RMS.
