Cast Tool Steel

Carmo die components

These Carmo die components represent the new Ford Motor Company die standard for constructing dies to work on DP 600 advanced high-strength steels.  The punch is a one-piece construction; the Carmo matrix, 7 feet by 3 feet, mounts on a cast-iron die shoe measuring 10 feet long and 18 inches tall.

Bottom: Draw punch
Top: Matching matrix

These International Casting Corporation dies were featured on the cover of Metal Forming (February 2006)

Steel casting is a specialized form of casting involving various types of steel. Steel castings are used when cast iron cannot deliver enough strength or shock resistance.

Steel is more difficult to cast than iron and has a higher melting point and greater shrinkage rate, which requires consideration during mold design. Risers should be given more capacity to draw from as the metal cools and shrinks. Also, attention should be paid to the thickness of mold cavities, as thinner areas will cool quicker than thicker areas, which can create internal stress points that can lead to fracture.  ICC takes all of these factors into account when making a superior casting.
