Aerospace component manufacturing, testing, and development are often split across multiple suppliers: one firm for engineering, another for machining, a third for welding or finishing, and an outside lab for qualification. Every handoff adds lead time, documentation risk, and another chance for design intent to get lost.
NMG Aerospace closes those gaps. As a vertically integrated aerospace supplier, NMG delivers end-to-end component development, manufacturing, and testing for aerospace OEMs, covering everything from the first design review through final qualification testing. One partner is accountable for how a component is designed, built, and proven.
Aerospace Component Development and Engineering
Most of a component’s cost and manufacturing risk is locked in during design. Material, geometry, tolerances, and joining methods determine how a part will be machined, welded, finished, and inspected, and changing them after tooling and qualification is expensive. That is why we bring engineering in at the earliest stage at NMG.
Our aerospace product design engineers work with OEM engineering teams to define the performance requirements, operating loads, and service environment that drive the design. At the same time, we flag the manufacturing constraints tied to each design decision.
Aerospace design for manufacturing (DFM) applies that production knowledge to the design itself:
- Tolerance allocation: Holding tight tolerances only where function requires them reduces machining time and inspection burden without affecting performance.
- Geometry and tool access: Internal radii, pocket depths, and wall thicknesses sized for standard tooling shorten cycle times and reduce setups.
- Datum structure: A GD&T datum scheme tied to functional interfaces lets the part be fixtured, inspected, and assembled from the same references.
- Joining and process selection: Weld joint access, fixturing that controls distortion, and finishes matched to qualified special processes keep assemblies in tolerance and avoid late-stage outsourcing.
NMG’s design experience spans deicing valves, solenoid valves, hoses, potable water and waste tanks, evacuation system subcomponents, wheels and brakes, and crew seating. Because we also manufacture and test these products, our design guidance is grounded in real production and qualification data.
From Prototype to Aerospace Production
A validated design is not the same as a production-ready one. Scaling from prototype to rate production introduces new variables: process repeatability, fixturing, tool wear, raw material supply, and inspection capacity. At NMG, we manage the transition as one continuous process. Prototypes are built on production-representative processes and tested in-house. Manufacturing engineers define machining sequences, weld procedures, and fixtures before plans are locked. First article inspection then verifies the process yields conforming parts before rate production begins.
Decades of building components for landing, fluid, pneumatic, and safety systems let our engineers spot production risks early, such as features likely to distort during welding or tolerance stacks that will not close in assembly. Catching them in development keeps them from becoming rework or schedule slips.
NMG Aerospace’s Manufacturing Capabilities
Many suppliers call themselves full-service but subcontract welding, finishing, or testing. NMG performs these core processes in-house across our facilities in Stow, Ohio, and Tempe, Arizona:
- Precision machining: More than 40 CNC machining centers, mills, and lathes deliver precision machining of aluminum, steel, and titanium to tolerances well within thousandths of an inch, with nonconventional processes like ECM and EDM for hard materials.
- Welding and fabrication: Nadcap-accredited aerospace welding to AWS D17.1, sheet metal fabrication, and precision tube bending.
- Special processing: Nadcap-accredited chemical processing such as anodizing and passivation, plus heat treating, brazing, painting, and shot peening through our special processing operations.
- Assembly and MRO: In-house aerospace assembly, plus FAA Repair Station and EASA Part 145 approvals for maintenance, repair, and overhaul.
Keeping these capabilities with one vertically integrated aerospace supplier eliminates the transit time, queue time, and paperwork transfers that come with outside processors. Both NMG facilities are AS9100:2016 and ISO 9001:2015 certified with design, and our Ohio facility holds Nadcap accreditation for welding and chemical processing. That keeps documentation and traceability with one supplier instead of spread across several. Machine shops can make the part, design firms can draw it, and test labs can qualify it, but few suppliers do all three under one roof. NMG supports both NMG-designed and build-to-print components, from full development programs to turnkey aerospace machining of an existing design.
Aerospace Component Testing and Validation
A part can be dimensionally perfect and still fail from vibration fatigue, thermal cycling, or fluid ingress. Testing provides objective evidence that a component meets its specification across the full range of conditions it will see in service.
NMG’s aerospace qualification testing capabilities are aligned with RTCA DO-160 and cover temperature, thermal shock, altitude, humidity, vibration, operational shock and crash safety, waterproofness, fluid susceptibility, and icing. Our engineers also build custom protocols that combine multiple variables to reproduce a specific service environment.
Testing is one layer of how NMG confirms a component meets specification. CMM and in-process inspection verify dimensions, controlled and documented operations verify the process, and qualification testing verifies performance. Because the same organization designed and built the part, a test failure leads straight to root cause, with direct access to design data, process records, and the people who made it.
Partner With NMG for Aerospace Component Manufacturing
OEMs need more than a supplier that can make a part. They need one that can get the design right, prove it works, and deliver it at rate. NMG brings aerospace component manufacturing, testing, and development in-house, backed by decades of experience across commercial aerospace, military and defense, and industrial manufacturing programs. That is what makes NMG a trusted aerospace manufacturing partner.
