Wiredrawing, Dry

Drawing in which soap powders or grease are used as lubri­cants and the wire is wrapped round the capstans a sufficient number of times to ensure that no slip occurs. The lubricant is placed in a container (die box) in front of the die and picked up by the moving wire as it passes through. Usually used for non-slip machines drawing ferrous wire above 0.61 mm, although some slip-type machines have also used dry soaps.
