Established in 1990, Viganò S.r.l. at Dolzago (LC) is a business that designs and manufactures machines, accessories and complete lines for sheet metal working. Silvano Viganò, sale director of Viganò S.r.l., says: «The market requires customizable and flexible plants, easily equipped and able to carry out more and more exacting machining operations and to work a big variety of thicknesses and materials, like carbon steels, hot-rolled and cold-rolled sections, stainless steel, aluminium, brass and copper, in general increasingly resistant. This is achieved “by oversizing” machines and adapting related accessories and devices, such as shears, coilers and so on. At present, lots of customers demand very low price lines and machines, which, obviously, is not possible, especially in the slitter case». The range is subdivided into slitting lines for small thicknesses, that is to say included between 0.20 mm and 3 mm; for “medium thickness “up to a maximum of 8 mm; for “big thickness “, up to 16 mm, which needs stiff and compact structures. Silvano Viganò adds: «Our machines, moreover, are characterized by easy handling inside the workshop because they do not need ground foundations but they are positioned on frame. This concept of “mobile machine” has been studied to satisfy the evolving requirements of service centres, facilitating the moves in case of modifications and changes inside the production factory. Our slitting lines can be integrated with additional machining stations, like mechanical and chemical pickling ones, in order to supply a more and more complete product».
Silvano Viganò adds some further technical observations: «Today customers generally exact higher quality machines in comparison with the past and, in particular, requests concern lines able to work structural steels and/or high strength steels with low thickness, up to yield values exceeding 1,000 MPa». Silvano Viganò ends: «In the future, it is unlikely that we will see revolutionary innovations, but in the best case the optimization and integration of already known technologies in a single line. The slitting of high-strength steels, for instance, will be integrated with in-line stretching or cleaning/brushing processes, so that customers can obtain a piece finished at best, with already ready surfaces for painting or successive treatments. I believe anyway that the greatest progresses will derive from the development of electronics».
