Binders are a big part of the coresand making process. Green sand cores are made from standard damp moldingsand 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. .
