From Napkin Sketch to Finished Product
We design, prototype, and manufacture your product under one roof — and you keep 100% of the IP. 10+ years helping inventors and founders build real products.
One team takes your product the whole way
No vendor juggling, no handoffs, no lost momentum.
Why founders pick RMA
You keep 100% of your IP
No royalties, no equity, no licensing claims. Your CAD files, your drawings, your prototypes — contractually yours, always.
Real engineers, in-house
Mechanical engineers on staff in New Jersey do the work. No outsourced mystery team, no salespeople writing specs.
Honest numbers
Most projects start around $2,000, and basic products typically run $6,000–15,000 through design and prototyping to manufacturing-ready. Every stage is a separate go/no-go — you never commit to more than the next step.
Hourly or per-deliverable billing
No flat "packages." You pay for engineering output you own.

What our clients say
RMA Engineering was an invaluable partner in consulting on the designs and applications for three of our recent projects. Their expertise and guidance helped ensure that every detail was executed flawlessly. Our customers were absolutely blown away with the end results, and expectations were exceeded across the board. RMA's team is friendly, professional, and extremely easy to work with. I look forward to collaborating with them again on future projects and highly recommend their services.
Reid and the team at RMA Engineering have been the perfect partner in launching our 3D printed eyewear. From the start, they've shown incredible patience and attention to detail, going above and beyond with designs, revisions, and communication. Their expertise has not only helped us bring our vision to life but has also made the process smooth and collaborative.
