Ramu Bhumgari

Chief Executive Officer & Owner

Ramu Bhumgari is the Chief Executive Officer and owner of Sigma Precisions. He leads the company with full accountability for strategy, customer relationships, and delivery—setting the standard for how precision programs are engineered, qualified, and supplied from our Hyderabad facility.

Under his ownership and direction, Sigma Precisions operates as an end-to-end partner for mechanical and electro-mechanical components: design and engineering, prototype manufacturing, qualification and reliability testing, and low-to-medium volume production for power generation, aerospace, and oil & gas.

Customers work directly with a company whose leadership is invested in outcomes—not as an employee of another brand, but as the principal responsible for every commitment made under the Sigma Precisions name.

Who we are

Sigma Precisions designs, develops, prototypes, tests, and manufactures precision-engineered systems and components. We work with customers who need more than a machining quote—they need a company that can carry a part from concept through qualification and into reliable supply.

Our work spans mechanical and electro-mechanical products, alternate process development, and the materials challenges common to power generation, aerospace, and oil & gas—guided by the vision and ownership of Ramu Bhumgari.
