Cast in Inserts
Cast-In Inserts are normally made from cast iron or
steel. A metal core needs to be placed in a mold so
that it is parallel to the parting line of the mold to
allow for it to be readily removed before the casting
is ejected from the mold cavity. The shape of the
insert must also be conducive for an easy removal from
the casting. Cast-in inserts allow for a better
surface finish and rapid solidification of the
casting, which improve the grain structure and
subsequently the mechanical properties of the casting.
Examples of cast-in inserts would be wear resistant
pins, heating elements, or even aluminum extrusions.
