Here ya go. Just be warned that graphite and cheap do not belong in the same sentence.
Anyone know of a good ( cheap ) place to get graphite blocks, looking for 4" square by 1.5" thick, not for edm but for metal casting, what sort of price does graphite go for?, I know it's not an EDM question, but you edm'ers should know where to get graphite.
( never stop learning )
heat it up first. I tried it, and was amazed at how fast the metal chilled going into cold graphite molds.
It works really well as a mold for glass, though.
I buy all my graphite from Tokai Carbon Europe. They manufacture many different types of graphite and are very reasonably priced. They are based in west midlands tel no 08001695647. Hope this helps.
