Sometimes the answer needed is so large as to be hard to give without writing a book. Pretty poor attitude to have consdering all of the knowledge freely given at this site.
Very short explanation is you need a die set to hold the male and female coining dies. The dies need to be made in such a way as to allow the stock thickness inbetween the impressions. A press is needed to mount the die set in. This is usually a blyth type with a flywheel that stores energy for the stroke. Hydraulic presses can be used but figure much slower production. Ultimately this whole thing isn't cheaply done on any scale where you'd be making proiduct for sale. The number of parts needing to be made and sold would be huge to recover the costs.
Intricate dies aren't cheaply made. Die shoes aren't cheap, Presses aren't cheap. If you have a CNC mill, you could make your own die steels. You could cobble together some sort of apparatus to take the place of a precision die shoe. You could cobble together a HF hydraulic press to make some end product. You would never reach any sort of production capability to pay off the venture so you'd have to realize what you were doing was a hobby level effort.
The answer is a far cry more involved than telling someone to use a felt pad and water on a slow buffing machine with fine rubbing compound. I don't cringe at telling how to do this due to a loss of money. I cringe because it took me four years of working every day to learn and understand everything needed to have something like this work right the first time. You can't boil a four year apprenticeship down into a thousand word how to do it post.  |
