Abstract: An apparatus for manufacturing simulated stone products. The apparatus comprises a mold having one or more mold cavities. The mold cavities have a first section and a second section. The first and second sections have a longitudinal axis. The longitudinal axis of the first section intersects with the longitudinal axis of the second section to form a cavity angle. The first and second sections have top openings. The first and second sections are positioned such that castable material introduced into the top opening of the first section flows by gravity into the second section. At least one cover member is removably connected to the top opening of the second section of the mold cavity. The at least one cover member is configured to contain the castable material within the second section of the mold cavity as the castable material flows into the second section of the mold cavity. The at least one cover member is removable to allow the simulated stone product to be removed from the mold cavity after hardening.

Abstract: A mold for manufacturing a simulated corner stone product includes a flexible layer that includes one or more corner stone shaped mold cavities. A cover is removably positioned against each mold cavity such that a back face of each corner stone product is formed with a desirable molded interior angle.
