Robotics Manufacturing & Fabrication | MJM Manufacturing

Precision Sheet Metal Fabrication for Robotics & Automation OEMs

MJM Manufacturing provides precision robotics manufacturing and fabrication — sheet metal fabrication, machining, welding, powder coating, and OEM manufacturing support for robotics and automation applications. We produce the custom enclosures, chassis, brackets, frames, and precision components that robotics and autonomous systems are built around, from prototype through full production. AS9100 certified, ISO 9001 certified, with tight-tolerance fabrication and DFM engineering support on every program.

Robotics fabrication demands tight dimensional tolerances for component fit, clean welds for structural integrity, and repeatable accuracy across production runs — all of which are core to our in-house fabrication process.

Materials We Fabricate for Robotics

MJM Manufacturing works with the full range of materials used in robotics and automation:

Aluminum (5052, 6061) — lightweight enclosures and structural components
Stainless steel (304, 316) — corrosion-resistant and washdown-environment components
Carbon steel (CRS, HRS) — structural frames and bases
Galvanized steel — structural members for industrial environments
Copper and brass — electrical and shielding components
Polycarbonate and non-metallic materials — guarding and panels

Precision Fabrication for Robotics Applications

MJM Manufacturing supports robotics and automation manufacturers with precision fabricated components, assemblies, structural systems, and production manufacturing built for demanding industrial applications. Our automated inspection — the Amada Fabri-Vision and Keyence measurement systems — ensures dimensional accuracy across production runs. See our full equipment and inspection capabilities.

Prototype to Production Manufacturing

Many robotics OEMs start with a prototype run to validate form, fit, and function, then transition to ongoing production with MJM as their long-term fabrication partner. Our engineering team provides design for manufacturability (DFM) review before the first prototype is cut — included at no charge as part of our quoting process. MJM also supports broader OEM manufacturing programs across industries.

Why Robotics OEMs Choose MJM

Tight-tolerance fabrication — ±0.005″ laser cutting for precise component fit
AS9100 & ISO 9001 certified — audited quality management systems
Full in-house process — cutting, forming, welding, machining, assembly, finishing under one roof
Automated inspection — dimensional verification and documentation
Prototype through production — scale without changing vendors
DFM engineering review — catches manufacturability issues before the first cut
47 years & 44,000 sq ft Miami facility — deep precision fabrication experience

As a customer, I have been working with MJM Manufacturing for approximately 35 years. The expertise of Mike Mijares and his team at MJM is top notch. Whenever I have a new part design, I typically review the design of the part with MJM to ensure that I am using the most cost-efficient manufacturing process to produce the parts as economically as possible. There was a part that we had made years ago using a progressive die to emboss a curved channel into a sheet metal part. The cost of the progressive die for this part was $55K. The redesign of the part from MJM consisted of $1200 in tooling to make the new part profile. Parts came out great and saved tens of thousands in tooling. Lastly, whether MJM produces a prototype or a production run, the appearance of the part is pristine, no tool marks or scratches on any part. In the 35 years that I have worked with Mike and his team, I have found them to be one big family. Mike’s love for his business is refreshing! You rarely see a person that is so charged to get up for work every day! Richard Havass Mechanical Engineering Manager JCI-Sensormatic

For over two years, MJM has provided our business with high quality sheet metal parts, and they also suggested improvements to part designs to help us reduce costs and improve assembly processes. They also keep their technology and machines up-to-date, so the new capabilities translate to new options for our customers.
