Mold assembly

A mold assembly for forming a countertop with an integral sink bowl, the mold assembly comprising:

• a female mold component comprising:
• a counter portion;
• a bowl portion recessed from the counter portion;
• a top surface;
• and
• a bottom surface opposite the top surface;
• a male mold component configured to be removably mated with the female mold component to at least partially define a mold assembly interior for forming said countertop, the male mold component comprising:
• a counter portion;
• a bowl portion extending from the counter portion of the male mold component and configured to fit at least partially within a space defined by the bowl portion of the female mold component when the male and female mold components are mated with one another;
• a top surface;
• a bottom surface opposite the top surface of the male mold component and configured to face toward the top surface of the female mold component when the male and female mold components are mated with one another;
• and
• a plurality of cavities spaced from one another and recessed inwardly from a portion of the bottom surface of the male mold component defined by the bowl portion of the male mold component;
• and
• an insert configured to fit within said mold assembly interior and conform to a size and shape of the bowl portion of the male mold component, the insert comprising a flexible and resilient material and further comprising:
• an inner concave surface configured to contact said portion of the bottom surface of the male mold component defined by the bowl portion of the male mold component;
• an outer convex surface that is opposite to said inner concave surface;
• and
• a plurality of protrusions extending outward from the inner concave surface and spaced from one another, each of the plurality of protrusions configured to engage with a different one of the plurality of cavities of the male mold component to inhibit separation of the insert from the male mold component.
