Founder's Message

A Visionary's Relentless Will

“I don’t stop when I am tired. I stop when I am done.”

— (Late) Mr. S. A. Ramamoorthy, Founder

He began at 51, when most would step away. (Late) Mr. S. A. Ramamoorthy chose to begin with conviction, discipline, and an uncompromising belief in doing things right. What he built was a way of thinking — where precision is non-negotiable, effort is absolute, and nothing is left unfinished.

Even today, his presence is felt across every shop floor, shaping how our engineering teams design, manufacture, and verify automotive components daily.

Key Executive Leadership

Work With Srimukha

Build the Future of Precision Engineering

At Srimukha, our power lies in our people. We foster an environment of high-tech learning, mutual respect, and absolute dedication to craft. From mastering multi-axis CNC, VMC and Grinding machines to participating in Inter-Unit sports competitions, we grow together.

Sustainable Practices

Sustainable Practices

Solar Energy Transition

Srimukha has invested in a dedicated solar power plant in Nagapattinam, Tamil Nadu, with an installed capacity of 4 MW across 15 acres. This clean energy investment currently supports 65% of our manufacturing operations, reflecting our long-term commitment to reducing our carbon footprint and building a more sustainable manufacturing base. In addition, we have installed rooftop solar systems across 2 of our manufacturing units, further reducing our dependence on grid power.

Resource Circularity

We follow a zero-waste approach to material use, recycling 100% of our steel scrap - chips, shavings, and cut-offs generated during machining are returned to the steel supply chain rather than sent to landfill. This closed-loop approach reduces raw material waste and supports responsible resource use across all 7 plants.

Clean Energy: 65%

Solar: 4 MW
