Eltech S.r.l. specializes in the tinning and cold drawing of copper wires, which are mainly used in the manifacturing of electric cables. It produces and markets both monowire and multiwire. During each phase of the production cycle, both of electrolytic tin-platting and of drawing of the wires, trained and skilled personnel constantly controls all the process parameters, in order to guarantee the achievement and the maintenance of the quality requirements arranged with the Customers and established from the internal standards.

Moreover, some tests and periodical controls are made on the variables of the processes, starting from the lubrificants to the wire drawing chain, till the galvanic products for the electrolysis. Finally the finished product is tested in an equipped laboratory, where skilled personnel performs the final test by means of modern equipments.

Standard products

Eltech S.r.l. can supply a huge range of products, some of which are standard, available in our stock or characterized by reduced delivery time.

The drawing department is able to produce both monowire and multiwire, bare or tinned, in spools with flange diameter of 250, 400, 560, 630, 800 mm. In particular, the monowire product can vary from a 0,10 mm to a 0,40 mm diameter in PVC spools with a diameter of 250 mm.

The electrolytic tin-platting department can produce copper wire with diameter from 1,50 mm to 2,50 mm, and with a variable thickness from 2 to 7 microns; this product is meant for a following re-drawing.
