A mold assembly for creating a resin casted countertop exhibiting a built-up edge having a non-constant radius. The mold assembly includes a substantially horizontally planar and upwardly facing mold surface and a plurality of elongated member which are releasably securable upon the planar mold surface to create an outline of a countertop product to be produced. Each of the elongated members include a planar edged top, a likewise planar edged bottom, a rear face and an inwardly contoured front face. The inwardly contoured front face includes a first constant center radius throughout a first degree of angular rotation and at least one additional upper and/or lower constant center radii throughout additional degrees of angular rotation proximate the top and bottom locations of the inwardly contoured front face. The inwardly contoured face permits the application of a liquid form surface coat material and prevents the pulling away or sagging of the surface coat during gelling or hardening and prior to the application of at least one back coat of material.
Cette invention concerne un moule servant à la production de dessus de comptoir en résine à rebord saillant à courbure variable. L'objet de l'invention comporte un plateau plan sensiblement horizontal et une série d'éléments amovibles de forme allongée définissant le contour du dessus de comptoir à fabriquer. Chacun des éléments amovibles présente un dessus et un dessous plans, une face extérieure et face intérieure profilée en creux. Le profil en creux présente une première courbure de rayon constant dans un premier secteur et au moins une autre partie incurvée de rayon constant différent à la limite inférieure et/ou supérieure du premier secteur. Le profil en creux permet l'application d'un matériau de revêtement liquide et prévient le décollement ou l'affaissement du revêtement en cours de gélification ou de durcissement et avant l'application d'au moins une couche de matériau de remplissage.
