Controlling
Pattern Costs
One of the manufacturing costs in
casting is the cost of preparing the pattern.
The pattern is used to form the cavity in the sand
mold. The cavity is shaped to the desired contours and dimensions of the final casting.
The pattern is positioned in the the open frame
(flask) and sand is packed around the pattern. The pattern/tool is then removed, leaving
the casting cavity in the sand mold.
Aluminum
is the material of choice for this pattern. The casting engineer has a design choice on
how the pattern will be fabricated. The fabrication method will have a direct impact
on the cost of the pattern.
