Stewart EFI provides precision metal stampings for military applications that demand reliability under the harshest conditions. Our ISO 9001 and IATF 16949-certified processes, combined with full traceability and strict adherence to military specifications, ensure every part performs exactly as required. From ammunition casings to soldier systems, we deliver components designed for mission-critical performance through advanced defense metal forming techniques.
For rugged, seamless housings, munitions casings, and protective enclosures designed to withstand extreme environments.
For high-precision, mission-critical components produced efficiently at medium to high volumes, maintaining tight tolerances for military systems.
For complex, miniature, or intricately bent components used in soldier systems, electronics, and specialty defense applications.
Our stamping operations combine progressive die, deep draw, and multi-slide processes with in-house tooling and automated assembly to produce components that survive demanding military environments. This approach allows us to:
We supply OEMs and defense contractors with components that hold up where failure isn’t an option. Our team works with you to bring designs from concept to production quickly, with stamping capabilities operations under one roof for maximum flexibility. Applications include:
All Stewart EFI facilities are ISO 9001 and IATF 16949-certified. Our defense metal forming processes include in-die sensing, press monitoring, and 100% inspection for mission-critical features. Every part is fully traceable and compliant with military specifications, ensuring performance and reliability in the field.
Precision metal stampings for ammunition, soldier system hardware, protective housings, specialty batteries, sensors, and communication enclosures.
Yes. Our stamping processes are fully traceable and designed to meet MIL-STD, ASTM, and other military requirements.
We use progressive die, deep draw, and multi-slide stamping, combined with in-process monitoring, sensor-driven tooling, and 100% inspection of critical features.
Yes. Production-intent prototypes validate design and performance, and we scale efficiently to full-volume runs while maintaining tight tolerances.
Standard, specialty, and exotic metals, including plated or heat-treated alloys, for rugged, high-performance applications.
Our team collaborates on design-for-manufacturing, tooling maintenance, and process control to ensure parts perform consistently throughout their service life.
With more than 90 years of precision metal stamping experience, Stewart EFI delivers metal stampings for military applications that meet strict performance, material, and regulatory requirements.
