Drawing dies & cones

T hrough however many stages a thick rod is reduced in diameter to a fine wire, it never comes in

direct contact with the progressively smaller drawing dies that effect the transformation. Lubricant – just enough, not too much – ensures this.

Other essential agents that never ‘meet’ in a state-of-the-art drawing line are the entrance and exit cones at the extremes of the operation. In large part due to companies such as those reviewed here, they bracket a system in which the proof of technical expertise all along the line lies in the quality of the product in the payoff and takeup.
