One of the principle components of
making a quality casting is the
preparation of the sand into which
molten metal is poured. To that end,
Southwest Steel Casting Company operates
a laboratory for the testing of sand to
meet AFS standards and which conforms to
Southwest Steel's ISO-9001 procedures.
Below is a listing of laboratory test
equipment used by Southwest Steel to
insure that the sand used for our
casting process has the specified
properties necessary to produce a
quality casting.
