Quality & Lean Manufacturing

Stewart EFI is dedicated to exceeding customer requirements. By working smarter, striving for continuous improvement and remaining disciplined in our approach in all we do, we strive to achieve this goal.

To ensure total product quality and reduce variation, the overriding company objective is to make each product correct from the start. To meet this goal, we utilize advanced quality planning techniques, SPC, in-die sensing, and robust designs for tooling and processes. We also design our own unique variable gauges to support the company's SPC program. By practicing on-going lean manufacturing, 5S and quantitative goals and measurement programs, and by working closely with quality-driven suppliers, we ensure our quality, cost, delivery and service levels continue to improve. For safety critical components we offer 100% inspection of multiple characteristics utilizing mechanical, vision, electrical and eddy current systems.

Our commitment to quality, a zero-defect goal, continuous improvement and SPC programs pay off handsomely for our customers. By increasing customer product reliability and cutting total manufacturing costs, we've earned customer recognition and numerous testimonial awards as well as an enviable reputation in the marketplace.

All of our facilities are ISO / TS 16949: 2009 Registered.

Our teams work on a variety of programs such as Setup Reduction Time, Lean Process & Material Flow for plant layout, Strategic Inventory Management, Department Consolidation, Cell Manufacturing and Material Waste Reduction. Stewart EFI’s continuous improvement program dates back to 1990’s and has continually grown to meet customer needs and expectations.
