A molding process can utilize a mold assembly that includes a mold having a mold surface and a die having a die surface. The mold assembly includes plurality of protrusions that extend from at least one of the mold surface and the die surface. A molten material is placed within a portion of the mold, and the die is then inserted into the mold such that the plurality of protrusions span a distance between the die surface and the mold surface. The molten material is allowed to solidify, thereby forming a filter membrane that includes a plurality of integrally formed apertures.
