At MBX Aerogen, our cap and baffle assembly capabilities represent some of the most technically demanding work we do. These components are critical to the combustion systems of aerospace gas turbine engines — managing airflow, thermal gradients, and structural loads in environments that push materials to their limits. From individual sub-components through fully integrated assemblies, our team brings precision sheet metal fabrication expertise to every stage of the process.
From Individual Components to Complete Assemblies
Our cap and baffle work begins long before a final assembly takes shape. We produce the full range of individual components that feed into these systems, including housings, effusion plates, spring plates, common flanges, support plates, and stiffener brackets. Each part is fabricated to tight tolerances using aerospace-grade materials and processes, ensuring dimensional accuracy across every feature.
These components aren’t produced in isolation — they’re manufactured with the full assembly in mind. The fit between a housing and its mating sub-assembly, the alignment of effusion holes across a plate array, the precise geometry of a common flange — all of it matters. Our team understands the downstream consequences of upstream dimensional variation, which is why quality is built into every step.
Sub-Assembly Expertise
Cap and baffle systems are inherently complex multi-piece structures, and much of the value we deliver comes from our sub-assembly capabilities. We build tube and housing sub-assemblies, dynamic plate sub-assemblies, baffle sub-assemblies, and effusion plate sub-assemblies — each requiring careful sequencing, skilled welding, and thorough inspection before integration into the final unit.
Effusion plate sub-assemblies are particularly demanding work. The laser-drilled hole patterns that define effusion cooling performance must be maintained through forming, welding, and assembly operations without distortion or contamination. Our team has the experience and equipment to manage these requirements consistently, producing sub-assemblies that meet the exacting standards of aerospace OEMs and their supply chains.
Baffle sub-assemblies present their own challenges — complex geometry, tight fit requirements, and the need to maintain design intent through multiple forming and joining operations. We’ve produced these components across a range of engine programs, and that accumulated experience shows in the quality and repeatability of our output.
Full Cap & Baffle Integration
The finished cap and baffle assembly brings together all of these components and sub-assemblies into a single, inspected unit ready for delivery to our customers. This is where our process control, tooling discipline, and quality culture all converge. We track every assembly back to its constituent parts, maintain full documentation through the build process, and inspect final assemblies against customer-supplied engineering data.
Our AS9100-certified quality management system supports this work from the first cut to the final inspection record. Combined with our NADCAP-certified welding capability, customers can be confident that the assemblies they receive from MBX Aerogen reflect the same standards that govern the rest of their supply chain.
Why MBX Aerogen for Cap & Baffle Work
We’ve been producing precision aerospace sheet metal components since 1997. Cap and baffle assemblies have been a core part of our work for much of that time, and the knowledge base we’ve built around these programs is one of our most valuable assets. We understand the materials — nickel superalloys, cobalt alloys, stainless steels — and the processes needed to work them reliably. We understand the inspection requirements and how to document compliance. And we understand the schedule pressures that come with aerospace production programs.
