    摘要: The present invention relates to wax impregnated filters for use in investment casting applications and a method for forming them. The filters are characterized by a wax impregnated ceramic substrate, wax layers bonded to two opposed surfaces of the substrate, and peripheral edges having exposed ceramic surfaces which can be adhered to the ceramic liner of an investment casting apparatus. The method comprises providing a sheet of ceramic foam filter material, impregnating the sheet with sufficient liquid wax to form a wax layer of desired thickness bonded to each of two opposed surfaces of the sheet, allowing the wax to solidify, and precision cutting the impregnated sheet into filters having a desired set of dimensions. The method further comprises exposing the peripheral edges of each filter to allow the ceramic shell building or liner in the investment casting apparatus to bond directly to the filter.
