  • MODULAR CASTING SPRUE ASSEMBLY
    Publication number: 20140190650
    Abstract: A prefabricated sprue assembly provides attachment to independently-produced investment casting molds to substantially reduce the need for pattern material. Installable connections between the prefabricated sprue assembly and the investment mold allow substantial reduction of scrap loss caused by errors in production of individual investment molds by culling defective molds before installation to the sprue assembly.
