RPM & Associates was founded in 1982 by Rob Mudge, Deb Mudge and Rob's parents, Jim and Phyllis Mudge. RPM & Associates is a manufacturing firm located in Rapid City and is a South Dakota corporation. Our core customers are coal fired power plants, mining operations, cement plants, chemical processing plants, Department of Defense and aerospace. We are focused on solving wear problems for our customer base using innovative ideas, automatic welding systems, creative machining and proper material selection.

In 1996, our sister company, RPM Solutions, Inc., was started in a joint effort with Shawn Veurink.

RPM uses chrome-carbide hardfacing, tungsten-carbide hardfacing and laser cladding to increase performance and provide solutions for wear in power generation and other industrial applications. We rebuild and manufacture new coal pulverizer grinding rolls, grinding tables, pulverizer mills, coal pipe such as elbows and tangents, overlay plate, wear liners, and other crushing equipment used in high-abrasion environments
