Abstract
In a component such as a built-in sink, a washhand basin or the like, having a visible side and a rear side and consisting of a compound made of a resin which forms a matrix and of a filler comprised, at least predominantly, of quartz particles, in order to improve the wearing quality, the majority of the quartz particles have a size of between 0.1 mm and 2 mm, the filler constitutes about 60% to 80% by weight of the compound, the quartz particles have an unbroken grain shape and in the areas of the component subject to severe stress during use are packed more densely than those on the rear side of the component. To manufacture such a component, a mold is placed, for curing of the resin, in a position in which the visible side of the areas of the component subject to severe stress during use faces downwards.
