CEO visits Pune Plants, gets updated on new technology and processes, and honors team members’ years of service to Sigma Engineered Solutions.

In his first facility visit of 2023, President & CEO Vagner Finelli made the trip to Pune, India with CHRO Dan Johnson and Board Member Joe Del Toro.  Their multi-day trip to see some of our over 4000 team members was led by COO Niteen Inamdar.

The group spent the first day touring the Pune Operations, looking at new technology and production implemented throughout our manufacturing processes, reviewing new parts that Sigma has begun producing for new markets, and reviewing each plant’s safety procedures.

“We have added new technology in our Pune Plants, and I wanted to see firsthand how that technology has increased production and productivity,” said CEO Finelli.  “Additionally, I wanted to thank and celebrate with everyone who had a part in our AS9100 certification here.  I am continually pleased with our team’s strides in improving our processes, maintaining a safe work environment, and creating the best-in-class products offered.”

The AS9100 certification for Sigma’s Pune A5 Plant is the second AS9100D certification following our Markesan, WI facilities continued accreditation since 2017.  This certification allows Sigma to design, develop, or provide aviation, space, and defense products and services, including parts, components, and assemblies domestically or internationally.

The trip wrapped up on the second day honoring 25 employees for their years of service to the company.  “The dedication these employees have shown to Sigma Engineered Solutions is incredible,” said CHRO Dan Johnson.  “They are part of an amazing backbone that makes up this great company.”
