Metal injection molding shell case

Concurrent Technologies Corporation, a non-profit science research organization, and the US Army, have earned two patents for a shell case design made using metal injection molding (MIM).

According to the organization, the single-piece case is stronger, stiffer, and lighter than traditional brass. It can also withstand pressure of up to 100 ksi and has 10% more muzzle velocity compared to the traditional material.

“This award comes at a time when global commodity prices for copper and brass are at all-time highs,” said Edward J Sheehan, Jr, president and CEO. “The use of high-strength, lightweight stainless steel cartridge cases in ammunition production reduces manufacturing costs.”

“We’re extremely excited to get this advanced technology to the warfighter to reduce their combat load and increase their mobility and lethality,” said Shawn Rhodes, principal mechanical engineer.
