Punch, Laser Cutting & Forming

The most modern CNC laser cutting and 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.  Laser cutting is fast and flexible requiring no tooling and capable of complex shapes.

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.

Value added Assembly

RMFI offers value-added assembly services to save customers time and money. We will take responsibility for mechanical assembly into enclosures that RMFI fabricates. This turnkey process gives customers a single point of purchase, resulting in quick, flexible and cost-effective production of assemblies that are complete and ready to use. Each operation is custom-designed depending upon the product and application.

All equipment we produce passes through various levels of subassembly and final assembly, testing and inspection checks. Our final assembly area with dedicated production lines was established for the integration of the various components in the final assemblies.

Value added Assembly

Quality is a very important part of the fabrication process. RMFI is a certified ISO 9001:2008 company.

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.

Packaging & Delivery


RMFI's final process is packaging the finished product so it can be sent on its way.


We utilize our own fleet of vehicles to provide local delivery of parts. We work closely with the larger carriers for long-distance shipments. All to insure your parts are delivered save and when you need them.
