Abstract
The invention relates to a process for manufacturing artificial stone boards with polymerizable resins with a “veined effect” by means of the vibro-compaction under vacuum system comprising a first grinding phase of the different materials forming the filler, a second phase containing a resin with the catalyst and optionally a third phase consisting of the mixing of the two previous phases until the homogenization of the materials with the resin, a fourth phase of moulding and compaction of the obtained paste by vibro-compression under vacuum, a fifth hardening phase by polymerization of the resin by means of heating and a last cooling, cutting and polishing phase.
