Tungsten, with a density approaching 18.5 g/cm³, is widely used in applications requiring maximum mass in constrained volumes, superior wear resistance, and thermal stability. PTI Tech’s proprietary MIM processes enable the production of precision tungsten parts with geometries and tolerances not achievable through conventional pressing, machining, or casting.
PTI Tech has now launched tungsten MIM components into production for defence applications including:
- Energetic Devices: Tungsten setback pins and arming components requiring high density, mechanical strength, and repeatable tolerances.
- Ammunition Systems: Polymer-tungsten hybrid components and inserts that optimise weight distribution and survivability in advanced projectile designs.
- Counterweights & Balancing Systems: High-density tungsten masses for guided munitions, unmanned systems, and aerospace platforms where compact and precise balance is mission critical.
“Metal Injection Molding of tungsten combines near-net-shape design freedom with the performance of a refractory metal,” said Michael Wiseman, Business Development Manager at PTI Tech. “The transition of multiple tungsten projects into production demonstrates not only material capability but also the robustness of our process control for defence customers who require absolute reliability.”
Guy Mariella, Chief Technology Officer at PTI Tech, added, “With record-breaking pricing of APT and increasing concerns about tungsten supply chain scarcity, PTI’s investment in advanced MIM technology is more important than ever. By developing scalable, US-based solutions for tungsten processing, we are ensuring that our defence partners have secure access to this critical material without compromising performance or availability.”
PTI Tech’s end-to-end control is intended to ensure consistent density, dimensional stability, and mechanical properties across high production volumes. By keeping every step of the manufacturing process domestic, PTI Tech strengthens US supply chain resilience while delivering components aligned with Department of Defense requirements.
