Mold
Preparation
One
or both ends of the mold have removable end caps which are held on with
wedges or clamps. Removing the end cap allows removal of the casting from
the mold.
A
critical step in mold preparation is spray coating the interior wall of the
steel mold with a ceramic slurry at a controlled
thickness.
The
ceramic coating serves as a wetting agent that promotes the flow of
the molten metal into the mold, controls the heat transfer during
solidification, and acts as a parting coating for casting removal.
