Process Description: The constituents for making sand cores at foundries consist of sand, resin and a catalyst to quickly set the resin. A common practice in core production is the use of a phenolic-based cold box (PUCB). In the PUCB system, sand is added into the cold box mold and mixed with the binder (resin), typically phenolic-based.
