Precision Aerospace Sheet Metal Fabrication | MJM Manufacturing

AS9100 Certified Aerospace Sheet Metal Fabrication in Miami, Florida

MJM Manufacturing provides precision aerospace sheet metal fabrication, machining, welding, powder coating, and OEM manufacturing for aerospace and defense applications. AS9100 certified, ISO 9001 certified, and ITAR registered, MJM has supported aerospace programs since 1979 — with long-standing relationships with Boeing, Lockheed Martin, Northrop Grumman, BAE Systems, L3 Harris, Honeywell, Bell Textron, and Goodrich. We produce flight-quality enclosures, brackets, structural components, and complex assemblies from prototype through full production.

Aerospace fabrication demands the highest level of process control, traceability, and documented quality — and our AS9100 quality management system, automated inspection, and certified welding programs are built to meet it.
