Project Overview

The Challenge

A defense-sector customer required precision sheet metal enclosures and mounting components for an electronics program. The program was ITAR controlled, requiring a fabrication partner with documented ITAR registration, full material traceability, and compliance with AS9100 quality management standards.

Parts required certified material test reports (MTRs), in-process inspection documentation, and first article inspection (FAI) reports before production release. Tolerances of ±0.003″ on critical mating surfaces required consistent, repeatable precision across every production run. Delivery schedules were tied to program milestones with zero schedule flexibility.

The MJM Solution

MJM Manufacturing’s ITAR registered facility and AS9100 certified quality system made us a qualified source for this program from day one. We worked with the contractor’s engineering team through the first article inspection process, providing full dimensional inspection reports and material certifications before any production units were released.

Using our CNC fiber laser cutter for blank development and our press brake forming equipment for the formed features, MJM maintained the ±0.003″ critical tolerances across the entire production run. TIG welding was performed by our certified welders on all welded joints, with each weld documented per the program’s quality requirements.

Anodizing and chemical film finish were coordinated through our trusted finishing partners, with MJM managing the full chain of custody and quality documentation. All 250+ assemblies were delivered on schedule across six production releases with no nonconformances reported.

Scope of Work — Defense Sector

MJM Manufacturing fabricates components, enclosures, brackets, chassis, panels, and ground-support equipment for customers in the defense sector, produced to customer-provided drawings and specifications.

MJM does not design, manufacture, assemble, or integrate weapons, munitions, ordnance, firearms, or functional weapon systems. MJM’s ITAR registration authorizes the company to receive and handle controlled technical data; it is not a representation that MJM manufactures any specific defense article. Determination of application suitability, certification, and final acceptance is the sole responsibility of the customer.
