Titanium Castings by Sand Molding Process
Objective To produce industrialgrade titanium castings by processes that are nonpolluting and lower cost than the currently used rammedgraphite process. Approach Foundrygrade zircon and olivine sands, bonded by waterglass or bentonite, are used to make shell or rammed molds which require relatively lowdrying temperatures and do not generate noxious fumes during drying or casting.
