I may be able to supply an answer or two as I am a die maker. I am not sure what you are trying to find out though. You say several different types of pins use a die to punch brass or copper to make the impression using a press.
Are you talking about pins that would have a pattern or design pressed in them? This is called coining. Or are you talking about blanking out different shapes that are part of the pins? Do you have any pics or examples? Not sure how much help I may be able to provide. |
