Abstract
A method of making a cast product, includes heating an alloy to a temperature between about 1210 and 1470° F. so that the alloy is in a liquid state, injecting the alloy into a vertical die casting machine cavity, injecting the alloy into a mold having a gated configuration, wherein the injecting further comprises a shot velocity between 3-8 inches per second and a pressure between 5,000 and 14,000 psi, cooling the alloy in the mold, and forming the cast product, wherein the cast product is selected from a group consisting of suspension components, knuckles, control arms, transmission input housings, bed plates, swash plates, air conditioning compressor pistons, engine valve bodies, engine bed plates, transmission valve bodies, master cylinders, brake calipers, ABS braking components, shock mounts, engine bedplates, engine valve bodies and pump housings.
