This
casting could be produced by two types of molding methods.
GREEN
SAND MOLD
Moist, clay-bonded sand is tightly
packed around a wood or metal pattern in mold boxes. The pattern halves are removed, and
the mold is assembled with or without cores.
SHELL MOLD
Resin-coated sand is applied to heated
metal patterns forming shell-like mold halves. The shell halves are bonded together
with or without cores.
