JUNtoMFG is a manufacturing engineering service for hardware startups and Kickstarter creators. We review your design, build prototypes, cut tooling, and manage mass production — from our base in Ningbo, China's mold-making heartland.
Start with a $299 DFM Review Talk to an engineerNo instant-quote black box. A real engineer reads your files and replies.
Start small. Each step builds the trust — and the engineering confidence — for the next one. You never have to gamble mold money on day one.
We review your CAD files for manufacturability: wall thickness, draft angles, undercuts, tolerances, material choice. You get a written report telling you what will work, what won't, and what it will cost to fix — before you spend a dollar on tooling.
Functional prototypes to validate fit, form, and function. SLA, SLS, FDM printing and CNC machining in aluminum, ABS, and engineering plastics. Iterate fast, fail cheap.
Enclosures, brackets, chassis, and structural parts. Laser cutting, bending, welding, and finishing — the metalwork your product needs before it goes to mold.
Production steel molds, cut after your design has been DFM-reviewed and prototyped. No surprises: you approve the mold design and the trial shots before we commit to steel.
We run your production: factory selection, in-process QC, pre-shipment inspection, and logistics to your door. One accountable partner from first article to final carton.
Four steps. No platform, no ticket queue — you talk to the engineer doing the work.
CAD, sketches, or just an idea with dimensions. STEP, IGES, SolidWorks, or even a napkin drawing — we work with what you have.
A manufacturing engineer reviews your design and tells you what's manufacturable, what needs changing, and what it should cost. If your design isn't ready, we say so.
3D prints, CNC parts, sheet metal — small batches to prove the design. Most products need two or three rounds. That's normal, and it's cheap compared to a bad mold.
Molds get cut, first articles get approved by you, then production runs under our QC. We ship to your warehouse, your 3PL, or your backers.
Four facts. No superlatives.
Based in Ningbo, next to Cixi — the densest mold-making cluster in China. Our engineers visit factories in person. That is not a metaphor.
Our fee comes from you, not from the factory. When we recommend a supplier or flag a problem, there is no conflict of interest behind it.
The person reviewing your DFM is the person who will argue with the mold maker about your draft angles. You get direct access, by email, in English.
Most of our clients start with 500–5,000 units. We are set up for hardware startups and crowdfunding campaigns, not just container-load orders.
If any of these sound like you, we should talk.
You have backers waiting and a design that needs to survive manufacturing. We get you from funded to fulfilled.
You have an MVP and need DFM, prototypes, and a path to production without hiring a supply-chain team in Shenzhen.
You sell on Amazon or DTC and want your own product instead of another white-label. We handle the engineering side.
