Mold assembly for producing a countertop exhibiting an integrally formed sink bowl and built-up edge and method for producing the same

摘要

A mold assembly and method for producing a resin based countertop having an integrally formed sink bowl and a built-up edge. An elongate base is defined by a central surface area which is bounded by a plurality of interconnecting and elevated sides to establish a mold enclosure which is a negative shape of the countertop to be produced. A template is settable upon the elongate base and movable in a selected longitudinal direction so that an opening formed in the template is positioned in overlaying fashion at a desired location along the central area. A first sink bowl pattern is placeable in mating fashion within the opening in the template and upon the central area of the base prior to removal of the template. First applications of selected resinous materials are provided within the mold enclosure and around an exterior circumference of the first sink bowl pattern. A plurality of elongate barrier members are positioned within the mold enclosure atop the first applications of resinous materials and in inwardly spaced and parallel extending fashion relative to associated sides of the mold enclosure. A suspending platform incorporating a second sink bowl defining pattern is capable of being set upon the base so that the second pattern is arrayed in spatial fashion above the first pattern. A second application of a selected resinous material fills an open interior established between the first sink bowl pattern and the second sink bowl pattern and a further application of resinous material fills a channel established between the barrier members and the associated sides of the base to create the built-up edge to the countertop.
