The Metal Casting Design Steps

The Metal Casting Design Steps

The casting engineer has the job of determining how to produce the component as a metal casting.

The casting engineer studies the original design and determines how much latitude he has in fit and function to design for manufacturability and casting.

Once those considerations are defined, he goes through a specific set of decision steps to develop a casting design and a casting pattern/cores for making the mold.

1. Locate the parting line and orient the component in the mold.
	2. Review the design for draft angles and sharp radii.
		3. Identify and eliminate the hot spots in the component.
			4. Promote directional solidification in the component.
				5. Place and size the risers for adequate metal feed during solidification.
					6. Place and size the runners/gates to promote high volume, low velocity metal flow into the casting.
