The RMI® story.

True Excellence Exceeds Compliance.
Under the leadership of Roy’s son, Jerry Rothlisberger, RMI® continues the tradition of excellence that began more than fifty years ago. Today, we have twenty-three state-of-the-art CNC machine tools, a host of support equipment including O.D. grinding and honing, and a team of highly-skilled craftsmen all with one goal in mind: to provide you with the best quality products and customer service in the business. We use an advanced GibbsCAM CAD/CAM system for digital data file processing, and our facilities are certified to AS9100D and ISO 9001:2015. In 2015 RMI® acquired the assets of Noble Machine, adding highly-trained personnel, top-of-the-line manufacturing equipment, and one additional customer: Northrop Grumman Electronic Systems. We also increased our existing manufacturing space by more than 2,000 square feet.
At RMI® our team of manufacturing experts has been building precision components and assemblies for more than five decades. We have the knowledge and experience to deliver top-quality products on time, every time.

What's new at RMI®.

RMI® is Cyber-Secure per NIST SP 800-171
March 2023
More than ever before, today’s aerospace industry relies on secure and resilient supply chains to operate effectively and safeguard sensitive information. At RMI® we take our responsibility for securing Covered Defense Information (CDI) very seriously. To that end, we comply with DFARS clauses 252.204-7019 and 252.204-7020 and we follow the guidelines outlined in NIST SP 800-171.
We have successfully implemented robust security controls at RMI® to protect sensitive information from unauthorized access – including access management, encryption, and secure communication channels. Through our comprehensive security framework, we ensure that CDI remains protected throughout the manufacturing process, while our ongoing employee awareness program guarantees that everyone at RMI® understands their responsibilities for protecting CDI.
Over the years we’ve worked hard to build trust with our customers in the aerospace industry, and our commitment to Cyber Security strengthens these relationships and instills confidence in our products and service. At RMI® we are proud to do our part and contribute to the security and resilience of the US Defense Supply Chain. Please contact us for more information about Cyber Security at RMI®.
