I've been reading all the replies with interest, but in the end have to add some remarks:
85- 90% (maybe more if your buyer is cute) of the cost of bar solder is metal cost.
So you cant' really save that much money, or if apparently can you can you gotta ask how.
If you have a large quantity of used solder you can trade it as a down payment on your new
fill, you should get most of your money back, and I am pretty sure your vendor will give
you a better deal on a ton or so than he gives you on top up quantities.
So suggest you preliminary sound out your favoured vendor and if it sounds good, ask your
purchasing man to negotiate a deal. They love this sort of thing and he can end up looking
good, he certainly can't complain about the price anyway. Your vendor will also be keen to
do a deal like this and will be nervous of losing this business and your future business
so he will give you a good deal too.
You should ensure that at least 30% of your fill capacity is in cropped bar, fill chunks
or what ever to avoid possibility of heater damage. pack these in the machine before
turning on.
Solder is not magic stuff, it is amenable to rational processes so I don't see any reason
not to have a purchasing spec, if you really want to buy from a particular vendor because
of his perceived quality and service - again go down the canteen and sit in a corner and
dream one up. You don't have to be so obvious as to say each bar must have "Your vendors
brand name" cast in, but you get the idea.
Finally if your vendor is any good he will have some portable moulds for pot emptying, if
he doesn't then you can get what you need in the kitchen department of your hardware
store. Stainless ladles and aluminium food containers are perfectly fine. You will need a
lot of them mind.
Finally finally when doing anything like this make sure that you have proper protective
clothing/boots (no plastic) and that everything is DRY.
Goodluck
