shell core sand casting process

Shell Core Casting Skaigh Engineering

Shell core casting or shell moulding as it is also known as a process for creating a core that is used in foundry casting. Resin coated sand is blown into a preheated core box which is typically heated to temperatures between 220 - 235 degrees centigrade. The heated core box bonds the grains of sand together to create the finished shell core.

Shell Core Making - Aluminum casting molds with cores

The Sand Core process uses a chemically bonded sand to create a desired shape in a casting. The sand is heated in a core box, which allows for the chemical components in the sand to bond together and form the shape within the core box. The process of creating a sand core is quite similar to that of the creation of a sand casting mold.
