As a pioneer of shell molding in the United
States our casting operation has been recognized by the American
Foundry Society and by " Modern Casting Magazine".
All castings poured at Graham-Whiteare made using the shell
process, also referred to as the Croning process, in which
a resin coated sand is either dumped on a heated pattern
to produce a mold or blown into a heated core box to produce
a core. Shell molding produces castings with excellent surface
finish and tighter tolerances than other sand casting processes.
In general, dimensional tolerances are held to +/-0.040" for
pattern dimensions and +/-0.015" for cored dimensions.
The shell mold process is used to cast ten different grades
of gray iron, three grades of ductile iron, five grades of
brass and bronze alloys, and five grades of aluminum alloys.
Casting capabilities allow up to 35 lbs. in non-ferrous alloys
and up to 70 lbs. In ferrous alloys.
With Graham-White remanufacturing, we really do... make
the product better. Remanufacturing is more than just tearing down one
of our products when maintenance is due and replacing worn parts with
new ones. We do that and more! Because we designed the product, access
to original engineering specs with condemning limits is immediate. We
make your remanufactured parts better by installing any technological
upgrades or enhancements. Each remanufactured assembly is subjected to
the same rigorous testing as our new products and we have a warranty that
is the longest in the industry. Your original product is given a new life
that extends maintenance cycles and lowers life cycle cost. We can also
develop repair and return / or unit exchange programs to meet your needs.
