Pewter


#1

Hi Folks,

I need to find a source for pewter in casting shot or however it comes.
If John Henkel is out there, is there any special thing I need to know
about casting it?

Regards,

Try Contenti in Providence RI.
The tin alloys for casting white metal are usually sold in ingots. The
casting machine used for white metal casting holds rubber molds that are
about 12 inches in diameter. The center of the mold has a hole in the top
half- the sprues radiate outward to the cavities for the castings. It
takes a special vulcanizer to cure the molds. The casting machine spins
the whole mold disk (refered to as a pie plate mold) and the metal is
poured down a funnel at the center axis. The casting process is
centrifical, but a dozen or so parts are cast at once. The molds are
reusable like a wax injection mold. Several Providence RI companies such
as Contenti sell the equipment and the casting alloys. The most widely
used alloy is called 92- it is 92% tin with some copper and antimony and
contains no lead.
