What Sigma Electric Manufacturing Corp does

Sigma Electric Manufacturing Corp, doing business as Sigma Engineered Solutions, is a privately held precision metal manufacturer founded in 1982 and headquartered in Garner, North Carolina. The company designs and produces custom ferrous and non-ferrous castings, precision metal stampings, and machined components for industrial OEMs across fifteen vertical markets including electrical, automotive, aerospace, medical and dental, oil and gas, power transmission and distribution, electronics and telecom, fluid power, lighting, marine, appliances, food and beverage, power tools, energy, and commercial hardware.

The company's core technology stack spans four casting modalities (high pressure die casting, sand casting, gravity die casting, and investment casting) covering more than 260 metal and alloy combinations, complemented by precision metal stamping across more than 80 presses, Swiss CNC machining for miniature tight-tolerance parts, and partner services covering custom tooling, machining, surface finishing, heat treating, rapid prototyping, and automated assembly. Production is distributed across owned facilities in the United States, India, and Mexico, supplemented by third-party sourcing relationships in China, with a North Carolina warehouse enabling lead times as short as five days.

The business model is a B2B contract manufacturing motion: enterprise customers submit specifications through a Request-a-Quote process and Sigma handles design, tooling, production, finishing, and delivery as a vertically integrated single-source supplier. Pricing is custom and not publicly disclosed. The company has pursued inorganic growth, completing two acquisitions in 2019 (Avalon Precision Casting and Tooling Dynamics), and repositioned its brand in 2023 as Sigma Engineered Solutions to reflect a broader engineered solutions offering.
