Stewart EFI is dedicated to exceeding customer requirements through disciplined processes, advanced technology, and a culture of continuous improvement. Whether producing progressive, deep-drawn or multi-slide components, we build quality into every stage of production.
To ensure total product quality and reduce variation, our overriding objective is to make each part correct from the start. We utilize advanced quality planning techniques, SPC, in-die sensing, and robust tooling and process designs. Stewart EFI also develops unique variable gauges to support our SPC program, maintaining consistency for complex metal parts.
For safety-critical components, we offer 100% inspection of multiple characteristics utilizing mechanical, vision, electrical, and eddy current systems, helping customers achieve higher product reliability while cutting total manufacturing costs.
All Stewart EFI facilities hold metal stamping certification to the highest standards, including IATF 16949:2015 Registration. These certifications reflect our zero-defect goal, continuous improvement, and commitment to serving quality-driven industries.
Stewart EFI empowers self-directed teams under the guidance of our Plant Managers to improve processes and systems continually. These teams use Six Sigma and Lean Manufacturing tools, including 5S, Value Stream and Process Mapping, Cause & Effect Analysis, DOE Techniques, and Pareto Analysis, to identify true root causes and drive measurable improvements.
Stewart EFI’s continuous improvement program dates back to the 1990s and has continually evolved to meet customer needs and expectations.
