Abstract
A system for fabricating an infiltrated downhole tool for introduction into a wellbore includes a mold assembly including a binder bowl, a mold, a preformed blank, and a funnel. The binder bowl has a lower portion and a plurality of apertures extending through the lower portion. The preformed blank is disposed within the infiltration chamber to provide an attachment area for a body of the infiltrated downhole tool, and the funnel is disposed intermediate the binder bowl and the mold. The system further includes a binder flow channel which extends through at least one of the preformed blank, the funnel, or a displacement core disposed within the mold assembly, the blank being concentrically arranged around the displacement core.
