A machine for forming and fitting core support pins into wax ( ) surrounding a core ( ) prior to covering the wax ( ) with a frit ( ), includes one or more punch devices ( ), ( ) within its structure, so as to enable the forming of one or more indentations in each pin, intermediate its ends, thereby providing a designed weakness in the pin to cause it to more reliably follow slight relative movement which occurs between the pins and the part being cast, thus reducing stresses in the surface of the part.
