Hello,

I was told many years ago in a polycrystalline die seminar that if some of the diamond crystals extended too far out from the die surface , the extra drag could indeed produce a wire with a diameter smaller than that of the die. I however have never witnessed this myself. I imagine that there would be large striations on the wire and extra dusting if this occurred but again I have no first hand experience. Perhaps others will comment on this further.

Here are some books and videos for you to buy at the WAI Store:

I believe we might be able to do this, but it will have to be done after we return from Wire Expo. Please call Marc Murray @ headquarters 203-453-2777 Ext 121, he will be able to assist you in this matter.
