As far as I can tell, im probably the only silversmith here on
Ganoksin that has a fully equipped stamping and coin production
shop, capable of production runs of up to 10,000.
theres no question as to which way to go for making your charms, it
has to be via the drop stamping route.
Once you have the die, for what you describe is a one sided charm,
the hourly production rate after the blanking is in the hundreds per
hour. With as someone else has pointed out, coin proof quality
detail. Thats the standard i work to, as good as our Royal mint and
the US mint too.
Then if your going to make some in a gold colour, what you do is
plate the brass or to be precise the 70/30 alloy, first, after
blanking of course, then die strike after. Thats the normal way of
doing it. No problems with edge going green when in use. You could
also make the silver coloured ones this way too. Forget gold filled.
The plating is done in a tumbler by the 1000 and how much gold or
silver you put on depends on you pricing structure.
Then the die costs. I do turnkey solutions for customers like
yourself, and that includes the die making. You would normally stamp
in a collar, like coin making, the jump ring is put in a the hole
However!! im in the UK so logistically its difficult to supply you.
The reason is your customs and import regulations. Tho if the chinese
ex port to the USA then you can import from here.
Hope this is of some help. The right way forward for you is, of
course, to set up your own stamping shop. Easy if you know the right
persons!. and you control the whole operation, have all the work but
make all the profit. A drop stamping machine is really very simple,
if your any good with your hands you dont need much in the way of a
machine shop to build one. Ive done 3 with the 5 basic pieces of iron
from an old ones that were scrapped in the Birmingham jewellery
quarter. Even these you could make up yourself. My most used slide
hammer weighs in at 275 lbs. the smallest 50 lbs the biggest 450 lbs.
