You're a startup or growing brand that has outgrown assembling product by hand on a workbench, but doesn't have — and doesn't want to build — a factory floor. You need someone to take receiving, assembly, testing, and packaging off your plate at volumes that don't fit neatly into a big contract manufacturer's minimums.
What's different about assembly at this scale
Quality drifts without documentation
Manual assembly without written work instructions and inspection checkpoints gets inconsistent fast — and that variability compounds as volume grows.
You don't have a factory floor
Most product companies don't, and shouldn't. Coordinating assembly across multiple vendors fragments accountability and creates blind spots in quality.
Bench assembly doesn't scale on its own
What works when an engineer assembles ten units by hand doesn't translate directly to a repeatable production process at 500 or 5,000 units.
How RMA solves it
Documented process with QC gates
Every assembly job runs against written work instructions with defined inspection points, so defects get caught before they become a batch problem.
One point of contact for the whole workflow
We manage parts receiving, kitting, assembly, testing, and packaging as one job — one call, one team responsible for the outcome.
Assembly that scales with you
Whether you need 50 units or 5,000, our processes are built to flex without sacrificing the quality control you'd expect from a much bigger operation.
The kind of work we do
Mechanical sub-assembly builds
Fastened, press-fit, bonded, and welded assemblies built to your drawings with documented torque specs and fit checks.
Kitting and fulfillment prep
Component kitting, packaging insertion, and fulfillment-ready preparation for e-commerce and retail channels.
Incoming inspection and rework
Inspecting manufactured parts as they arrive and reworking out-of-spec assemblies, including product brought in for quality remediation.
What it actually costs
Assembly cost is quoted per job based on part count and process, but here's what the surrounding production numbers usually look like.
Manufacturing Tooling
$5,000–$50,000
If parts still need to be tooled before assembly can begin, this is the range to plan around.
First Production Run
$5,000–$150,000+
Ships in 8–16 weeks once parts and assembly instructions are locked — assembly labor scales with unit count.
