CTC Earns Patents for Metal Injection Molded Cartridge Cases
Johnstown, PA-based Concurrent Technologies Corporation has been granted two patents for its invention of a single-piece, high-strength metallic cartridge case that is stronger, stiffer, and lighter than traditional brass. The new shell case design is a joint development between CTC and the US Army aimed at enhancing warfighter effectiveness through increased lethality, improved accuracy, and reduced ammunition weight.
Metal injection molded cartridge benefits include a 30% case weight reduction vs. brass, high-pressure capability up to 100 ksi tested, increased muzzle velocity up to 10% over brass, increased accuracy, durable stainless steel case material with reliable functionality from -65°F to 160°F, rugged, single-piece design with no corrosion issues, and compatibility with existing brass case taper, trim, load, assemble, and pack manufacturing infrastructure.
CTC’s newly awarded patents 11465207 and 11493314 protect the US government’s ability to organically produce and supply the technology to the warfighter, while allowing cost reduction and maturation through private commercialization. The patented technology has the potential to reduce manufacturing costs at a time when global commodity prices for copper and brass are at all-time highs, says Edward J. Sheehan, Jr., CTC President and CEO. CTC’s team has analyzed requirements, developed a solution, and ensured it is cost-effective and scalable, he added.
The shell casing design inventors are Todd Skowron, Juan Valencia, Shawn Rhodes, and William Brueggen. CTC, an independent, nonprofit, applied scientific research and development professional services organization, collaborates with its technology transition affiliate, Enterprise Ventures Corporation, to provide transformative, full lifecycle solutions through research, development, test, and evaluation work. To best serve its clients’ needs, CTC offers the complete ability to fully design, develop, test, prototype, and build.
