P.C.D. Dies are used to draw both ferrous and non-ferrous metals at both high and low speeds due to its quality of thermal conductivity which enables it to observer the heat, which generates while drawing, from the die bore and also helps the die to maintain its diameter for a longer time. Now a days, wire drawing units are preferring the use of P.C.D. wire drawing dies instead of Natural diamond dies except in some special cases due to life & Re-Boring capacity obtaining from P.C.D. Dies.
