About Us

RSI Manufacturing began in 1995. Through the years our specialty has evolved from super simple production machining using custom-built special machines to complex high volume parts running in CNC machining centers.

RSI has over 170 combined years of experience within our management, design, and machinist personnel. These eight people are the core team that directs operations at RSI.  

RSI relocated to Muskegon, MI from Coopersville, MI in 2004, with over 40,000 square feet of manufacturing space. We are committed to the revitalization occurring in Muskegon.
