bull gear molding

casting (25)

A bull gear is molding

The Green sand is conveyed to the shop floor where it is ready to be used for molding. A pattern is placed between two halves of a flask. The top half of the flask forms the “cope and the bottom half the “drag”. Green sand is then placed into the cope and drag flask halves.

After squeezing the sand against the pattern, each half of the mold is stripped off the pattern. The resulting impressions in the sand form the mold cavity that the molten metal will fill to form a casting. The pattern is then removed and the mold halves put back together. The result is a finished mold that is ready for pouring.
