The know-how acquired in the micro-embossed film sector has allowed Simec Group to develop exclusive production processes, specific galvanic treatments, a vast sample catalogue of both standard and customised engravings on customers' request and technologies for chemical matt coating suitable for the purpose.

Most of these rollers are engraved on a galvanic nickel underlayer, preferring it to copper as it is more resistant and can guarantee surface homogeneity when the piece is finished. Simec Group can work rolls with maximum diameters of 1000 mm and face length up to 5500 mm, but the real specialisation comes from its ability to produce innovative engraving profiles for both wet and dry lines, studying geometries that can not only modify the characteristics of the film after embossing but also reduce any swelling of the material, by increasing the weights of the spools.
