Coremaking: Life of a Casting Reliance Foundry

Binders are a big part of the core-sand making process. Green sand cores are made from standard damp molding-sand mixtures, and a binder, like dextrin. Cores of this type are very fragile and can be made with an arbor or interior wires to facilitate handling. Dry sand cores do not contain water. They are made from silica sand and a binder to harden the surface. Linseed oil is an important

Core (manufacturing) Wikipedia

The simplest way to make a dry-sand cores is in a dump core box, in which sand is packed into the box and scraped level with the top. A wood or metal plate is then placed over the box, and then the two are flipped over and the core segment falls out of the core box. The core segment is then baked or hardened. Multiple core segments are then hot glued together or attached by some other means
