Responsible Metal Fab. Inc., (RMFI, www.responsiblemetal.com) is a California-based precision sheet metal fabricator and machine shop working from prototype through production, as well as offering electromechanical assembly and other services.

RMFI’s ISO-certified and ITAR registered processes include machining, sheet metal, prototyping, punch and forming, welding, finishing, assembly, design, engineering and production. CNC punching systems that punch, cut, and separate parts from the sheets, are highly accurate, fast and can be re-programmed when a part is revised.

CNC press brakes bend parts to precise dimensions as ordered in a customer’s drawings. These drawings are maintained in RMFI’s server to facilitate rapid set-ups for on-going or revisited production jobs.

CNC vertical mills offer versatility, accuracy and fast response to customer changes. Programs are stored in the RMFI server for quick reference on repeat jobs.
