Precision Metal Stamping
Stewart Efi produces high-precision metal stampings using advanced progressive die and transfer press technologies. Our capabilities include complex geometries for automotive, medical, and military applications. We ensure tight tolerances and material efficiency through automated processes and in-die sensing systems.
Deep Drawn Components
Our deep drawing process creates seamless cylindrical and complex-shaped components from coil stock. Utilizing large transfer presses, we manufacture parts for fluid systems, connectors, and industrial equipment with exceptional strength-to-weight ratios and surface finish quality.
Progressive Die Stampings
We employ multi-station progressive dies to produce high-volume, intricate parts with consistent quality. This method supports continuous production of terminals, contacts, and structural components for electronics and automotive sectors.
Slide-Formed Components
Our four-slide forming technology creates complex, multi-bend parts from wire or strip material. This process excels at producing small, high-precision components for medical devices, electrical connectors, and precision instruments.
Automated Assembly
We integrate automated assembly systems for metal components, including welding, staking, and mechanical fastening. Our capabilities ensure precise, repeatable assembly of complex subassemblies for automotive sensors and industrial equipment.
