Description
Graphite molds are commonly used in aluminum, gold and silver
casting. Benefits of graphite permanent molds are realized
by combining the low cost associated with machining graphite and
high strength common to graphite materials, providing an
economical alternative to other molds in the zinc-aluminum casting
industry.
