Inconsistent quality across batches
Manual assembly without documented work instructions and inspection checkpoints leads to variability that compounds at volume — returns, rework, and customer complaints.
No dedicated assembly infrastructure
Most product companies don't have a factory floor. Coordinating assembly across multiple vendors fragments accountability and creates quality blind spots.
Scaling from prototype to production assembly
Prototype assembly done by engineers on a bench doesn't translate directly to repeatable production. The gap between the two often catches companies off guard.
How RMA solves them
Documented assembly processes with QC gates
Every assembly job at RMA runs against documented work instructions with defined inspection points. Defects get caught before they become batches.
Single-point accountability
RMA manages the full assembly workflow — parts receiving, kitting, assembly, testing, and packaging. One call, one point of contact, one team responsible for the outcome.
Scalable assembly infrastructure
We bridge the gap from prototype assembly to production. Whether you need 50 units or 5,000, our assembly processes are designed to scale without sacrificing quality.
What we assemble
Mechanical Sub-Assemblies
Fastened, press-fit, bonded, and welded mechanical assemblies built to engineering drawings with documented torque specs and fit checks.
Full Product Builds
Complete product assembly from individual components to finished, packaged goods — ready for fulfillment or distribution.
Kitting & Packaging
Component kitting, retail packaging, insertion of documentation, and fulfillment-ready preparation for e-commerce and retail channels.
Functional Testing
End-of-line functional tests to verify product performance before shipment. We define the test criteria with you and document every result.
Inspection & Rework
Incoming inspection of manufactured parts and rework of out-of-spec assemblies — including third-party product brought in for quality remediation.
Low-to-Mid Volume Runs
Optimized for 50–5,000 unit production runs where flexibility, quality control, and fast turnaround matter more than fully automated line efficiency.
"RMA Engineering transformed our concept into a production-ready product. Reid and his team brought deep expertise and a hands-on approach that made all the difference. They understood our application immediately and delivered a prototype that exceeded our expectations."
