ABSTRACT:
A mold apparatus for forming various sizes and shapes of wax castings to provide a means for producing rings in volume therefrom, wherein the mold apparatus comprises a drum member defining the main mold housing having a casting bore of a pre-determined configuration disposed therein, the housing being provided with a pair of removable end plates, the plates being held in place by a tubular support mandrel passing through the cavity and the end plates; wherein a ring-sizing band can be received within the cavity to control the overall size and thickness of the wax casting; and wherein there is included a finger-sizing band adapted to be mounted on the tubular support mandrel within the casting cavity, whereby the selection and arrangement of various sized bands will form numerous ring configurations and sizes when hot wax is injected through an injector inlet port formed between the drum and one of the end plates.
