Full-Service Manufacturing at RMI

There is a lot more to manufacturing precision-machined parts than just the precision machining. Many of our customers require completed components – including processing and hardware – that are ready for stock or the assembly line. RMI® is proud to be a full-service manufacturer offering precision CNC milling and turning, O.D. grinding and honing, and in-house light assembly services. We also work with a wide variety of NADCAP-approved outside processors to provide: heat treating, welding, brazing, plating, painting, testing, cleaning, polishing, and more. Like our precision machining operations, all of our light assembly and outside processing services are performed by highly-trained craftsmen in strict compliance with your drawing and contract specifications.

When it comes to full-service manufacturing, RMI® has the knowledge, the facilities and the expertise you need to get the job done right and delivered on time, every time.

The Rothlisberger Manufacturing Story

After moving to Southern California in 1960 and working for several local aerospace manufacturers, Roy Rothlisberger founded Rothlisberger Manufacturing, Inc. (RMI® ) in his garage just north of Los Angeles in 1968. Roy’s combination of quality workmanship and exceptional customer service was a recipe for success and the new business grew and prospered. In those days there was no such thing as a vision statement, but if there was it would have been: “True Excellence Exceeds Compliance.” The following decade saw steady growth and an increasing base of satisfied customers; and in 1978 RMI® moved to its current location in Van Nuys, California.

“True Excellence Exceeds Compliance.”

Roy Rothlisberger, Founder

Under the leadership of Roy’s son, Jerry Rothlisberger, RMI® continues the tradition of excellence 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 eighteen highly-trained 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.
