Meehanite
Castings: Meehanite Metal castings cover
any casting within the overall cast iron composition range that have been
produced by the Meehanite process.
This process involves a number of patented procedures seeking to control
and produce the desired graphite distribution and the desired matrix structure
in the casting. It depends primarily on the establishment of a melt of
desired degree of undercooling often referred to as constitution and the
controlled nucleation of this melt, usually by means of alkaline earth
silicide additions. It requires very careful slection of raw materials,
meticulous process controls and a very thorough knowledge of the foundry
behavior of cast iron.
The Meehanite process involves the use of standard procedures in all phases
of casting manufacture including gating and risering techniques, sand
control testing methods and many specialized molding procedures. It seeks
to eliminate guesswork, thereby resulting in an engineering product of
high integrity and reliability.
