Coremaking: Life of a Casting Reliance Foundry

A segmented core is put together after the curing stage. When the cores are smooth and joined they are placed in racks to wait for use in the mold. Cores are almost always placed carefully by foundry workers rather than inserted by a machine. Chaplets, if any, go down into the drag first, and then the core

The shell process utilizes sand coated with phenolic resin and hexamethylenetetramine. A release agent is used to allow separation of the core from the core box. The sand is fed into the shell machines and heat is applied to the core box from combustion of natural gas. The resin coating thermosets when the heat is applied, thus curing the core.
