The multiple sprue mold is a quick
and convenient method of producing five 10mm diameter wax
sprues each 130mm long. The mould is machined out of
aluminium and splits in two for easy removal of wax sprues.
The two halves are secured by wing nuts.
Before use, the internal
surfaces of the mould should be cleaned and lightly
powdered. Molten wax is poured into the mould and
allowed to set, the mould is then split and the sprues
removed.
