Abstract
Contoured molten metal filter cups having an interstitial flow space that is maintained between the inner-wall of a molten metal pouring cone, riser sleeve or mold and the outer wall of the filter cup are disclosed. The interstitial space provided by the contoured filter cups results in significantly increased molten metal throughput during casting operations, while simultaneously providing an increased level of filtering efficiency.
