Question:

Where to buy steel molds?

I need a custom mold builtIt will be simple, all I need is for it to cast aluminum, copper, and brass , up to 10 inches in diameter, and .035 to .040 inches thickI guess the alloy of the mold doesn't matter much, as long as it's steel or ironThis is all the information I can provide for nowAny ideas??

Answer:

there you have itEvy's given you the answer:)
for simple round thin discs why pi about casting them?? Go to a sheet metal shop who has a turret punchThey will knock them out at about the rate of 250 a minute ! OK, for larger discs like 10 dia they will either laser or water cut them but the principal is similar.
