Sigma Engineered Solutions

At Sigma, our vision is to be your partner of choice and a company you believe is great to do business with. We are committed to being a company that you trust more than any other to continually improve and innovate high-quality castings and precision metal stamping products that meet your needs.

Headquartered in Garner, N.C., Sigma Engineered Solutions has a global manufacturing footprint that includes 13 on-shore, near-shore, and off-shore facilities, as well as sourcing capabilities in China. Our North Carolina-based warehouse and logistics facility reduces fulfillment rates to as little as 5 days. Our vertical integration provides the lowest total cost of ownership for our customers by combining the competitiveness of global manufacturing with the responsiveness and service of a U.S.-based company.

Sigma Engineered Solutions consists of two divisions: Sigma Castings and Sigma Connectivity.

  • Sigma Castings has significant expertise across various forms of castings and a wide array of metals, and our products include an extensive line of electrical fittings and hardware for the industrial, commercial, and residential construction industry. Our casting capabilities are supported by state-of-the-art in-house tooling and special purpose machine design and manufacturing, which help reduce lead times and costs.
  • Sigma Connectivity specializes in high volume precision metal stamping, with expertise in working with very thin gauge metals under extremely tight tolerances to create precision components used in electronic connectors.
