We laser engrave plastic articles of various types that differ in shades and thickness. Usually we engrave plastics that are intended precisely for the laser engraving – a two layer plastic: after the upper layer is graved away, the colour of the lower layer is revealed. Very precise parts, letters, and graphic ornaments of various forms can be cut out from this material, it can be engraved as well. When plastic is engraved with a laser, it is sought that the surface would change the colour, plastic, intended for laser engraving, usually contains special thermal additives, while during the engraving of plastic of other types, the wanted result is not always obtained, due to impurities that are in the structural composition of the plastic.
