The CDC Load Cycle is Tailored with Chemistry

Initially, fill gas creates pre-load, pushing the piston or ram down, pre-compressing and removing entrapped air from the powder. Then, an ignition stimulus is applied causing combustion and rapid pressure rise that further compresses the metal powder to its final net or near net shape. CDC technology allows parts to be compacted up to 150 tons per square inch without tool failure; gentle, continuous and unique rapid loading cycle is partly responsible. The tool steels are typically of industry standard and the CDC process typically uses no admixed lubricants or additives in the powder when the powder is compacted.

Not All Materials Respond the Same

Not all materials respond to densification at higher CDC pressures in the same way. The graph, below, represents select materials that have been CDC compacted up to 150 tons per square inch. To date, several materials tested have benefited from a higher tonnage per square inch. Spherical powders typically do not compact well; however, higher densities have been achieved when compacting advanced stainless steel.
