Deep draw stamping remains one of the most efficient ways to manufacture cylindrical and enclosed metal components with exceptional accuracy. Stewart EFI partners with OEMs to turn complex designs into production-ready parts—delivering repeatable quality, cost efficiency, and supply chain reliability. With a global network of facilities and over 60 deep draw transfer presses from industry leaders like Waterbury Farrel and Minster, we produce and ship more than two billion components annually.
This combination of scale and precision makes Stewart EFI a trusted supplier for demanding OEM applications in automotive, electronics, medical, military, and other critical industries.
With expert DFM and engineering support, our team can review your component’s material requirements, ensuring manufacturing processes maintain consistent wall thickness, address grain and feed directions, and identify the optimal finishing processes. Whether you need an initial prototype, have large production volume requirements, or need to develop a just-in-time delivery plan, our project managers are ready to support your needs.
Our collaborative approach shortens lead times, increases repeatability, and helps you achieve consistent quality across millions of parts. Read more about the benefits of deep draw stamping and collaborating with the Stewart EFI team.
Selecting the right manufacturing partner impacts cost, quality, and performance. Stewart EFI offers a unique combination of expertise, capacity, and long-term value:
Over 90 years of precision deep draw stamping experience, supporting some of the most demanding industries worldwide.
Strategically located facilities across three countries, ensuring continuity of supply and reduced shipping times.
IATF 16949:2016 and ISO 9001:2015 certified, with 100% inspection options for safety-critical components.
Tooling is guaranteed for the life of the part, eliminating maintenance costs.
Production-intent prototypes and low-volume runs help OEMs validate designs before scaling.
In-press operations and optimized material usage lower scrap rates, labor needs, and total production cost.
Compared with machining, deep drawing stamping is ideal for high volumes parts with complex geometries, consistent wall thickness requirements, or tight tolerances. These parts are manufactured from solid metal blocks or sheet metal blanks, are ideal for orders with:
Deep draw stamping is generally most economical at higher production volumes. However, the process can provide highly repeatable, efficient production across a range of quantities for components. Experienced deep draw stamping companies, like Stewart EFI, can help you identify if your part is suitable for deep drawing processes, as well as the tooling and material requirements that can affect production costs.
After nearly a century in business, Stewart EFI has grown to become one of the largest suppliers of deep drawn components to OEMs and industries around the world. Backed by ISO 9001:2015 and IATF 16949:2016 certifications at our U.S. plants and a joint venture in China, Stewart EFI is ready to support your production needs at a global scale.
We serve a variety of industries including:
With manufacturing locations in Connecticut, near the Mexican border in Texas, and in China, we provide OEMs and Tier automotive suppliers with on-time delivery even for complex programs.
Some of the world’s most recognized brands trust Stewart EFI deep drawn parts for electronic and electrical applications. From enclosures to switches, brackets to housing, power management parts and more, our expertise delivers precision performance.
Rigorous production processes, quality controls, and automated systems help ensure our deep drawn parts meet the strictest standards for regulatory compliance and reliable results – from prototype development to high-volume production.
Operating in compliance with ISO 9001:2015 and IATF 16949:2016 standards, our deep drawn stamped parts supply OEMs and defense contractors with the components, enclosures, and hardware they need for mission-critical operations.
Deep draw stamping is ideal for cylindrical or enclosed parts with straight or tapered walls, including housings, cans, cups, and other symmetrical geometries, especially in high-volume applications requiring tight tolerances.
We work with a wide range of materials including carbon and stainless steels, aluminum, copper, brass, and exotic alloys. We can also process pre-plated, anodized, heat-treated, or inlayed materials.
Deep draw stamping consolidates multiple operations into a single, high-speed process. This reduces scrap, lowers labor costs, and shortens production time compared to machining, casting, or welding.
Yes. Our engineering team partners with you during the design stage to ensure the part is optimized for manufacturability, which helps reduce tooling investment and improve long-term reliability.
Absolutely. While we specialize in high-volume production, we also produce low-volume runs for highly complex parts and prototypes, helping OEMs validate designs before scaling.
Whether you need millions of precision components or an initial prototype run, Stewart EFI is an experienced deep draw stamping company that delivers the scale, engineering support, and quality systems to meet your requirements.
