Company Overview

Siddhi Integrated Manufacturing Services (SIMS) is a precision machining and contract manufacturing company based in Clarksville, IN. Since 2021, SIMS has grown from a two-Haas setup in a 300 sq ft garage to a climate-controlled 20,000 sq ft facility producing complex, tight-tolerance parts for demanding industries. As an MBE-certified business, SIMS combines modern equipment, engineering expertise, and rigorous quality systems to deliver repeatable results at competitive cost and turnaround.

Core Capabilities
