Our Capabilities

ISO Certified

Quality is a very important part of the fabrication process. RMFI is a certified ISO 9001:2015 company located in Sunnyvale, Ca in the San Francisco Bay Area.

This requires that a strict inspection procedure be utilized at every operation in the production process. First piece inspection is done for each step of production, and certificates of compliance are available when requested.

Punch & Forming

The most modern CNC punching systems are used to punch, cut, and separate the parts from the sheets. These machines are highly accurate, fast, and can be re-programmed whenever a part may be revised. We have hundreds of unique tools and dies in our inventory. This allows us to produce small or large quantities efficiently usually without NRE charges or extra tooling costs.

Our CNC-Press brakes are used to bend parts to meet the precise dimensions shown on the drawings. These machines are highly accurate, fast, and consistent in operation. Customer drawing files are maintained in our server to facilitate rapid set-ups for production jobs.


Today’s complex assemblies require the expertise that RMFI can provide.  Our capabilities range from TIG to spot welding, aluminum and steel.  Bring us your challenging welded assemblies.  We are ready to serve your requirements.


 We utilize the latest Pem Setters for accurate insertion of hardware. We stock hundreds of types of hardware items, from simple nuts and stand-off’s to exotic panel fasteners.
