The shell core process pre-coats the sand with a resin before pouring it into a pre-heated core box. Heat is applied to the surface until a thin, hard shell is formed. We use shell cores to reduce the bulk and mass of a core within a casting, or for castings that require tight dimensional controls and good surface finish.
