Send your CAD — designed in-house or by your own studio — and an engineer prices it. Approve the quote and DFM begins: geometry, material and tolerances refined for the process and volume the part will actually run on, before anything is cut. We're not an industrial design studio — we don't sketch concepts from scratch. But behind every part sit engineers, mold makers and industrial designers who guide yours to the best result the process can give.
Quick definition
Product and industrial design engineering takes a product's existing geometry — a CAD file from you or your design studio — and refines it for how it will actually be made: wall thickness, draft angle, tolerances, material choice, part consolidation and cost. It's design-for-manufacturing at the product level, not concept design from a blank page — the shape and brand intent stay yours.


Reviewed by a person, not just parsed
Upload a CAD file to an instant-quote platform and it prices exactly what you drew — including the wall that's about to sink, the tolerance that doesn't need to be that tight, and the six parts that could've been three. Send it to OperGo and an engineer looks at the whole product before it's priced, not just the one part in front of them.
What's included
Wall thickness, draft angle, tolerance stack-up and fixturing reviewed against the process that'll actually run your part.
The right material and process for what the part needs to do and the volume it needs to hit — not the one you happened to draw it in.
Multi-part assemblies simplified into fewer parts where it cuts cost and assembly time without changing function.
Specific, actionable changes that lower price — a relaxed tolerance, a simplified feature — with the cost impact of each one shown, not just a lower number.
The flow
Yours, or your design studio's — whatever stage it's at, rough or final.
Priced against the process and volume it'll actually run on — by a person, not a parser.
Geometry, tolerances, material and process fit reviewed — every change shown with its cost impact, so you choose what to keep.
The engineer who priced and refined your part owns it through production.
Where this fits
This is engineering an existing design for manufacture — geometry, tolerance, material, cost. If you need concept design, sketching or brand-level product design from a blank page, that's a design studio's job; we work directly with yours once the concept exists.
Per-part DFM catches a wall thickness or a tolerance. Reviewing the whole product catches the bigger wins — six brackets that could be one enclosure, a material used in three places that could be one.
If you have a design studio, bring them in from day one — we coordinate manufacturability directly with them, so design intent and production reality don't get lost between two email threads. If you don't, we can introduce you to one of the studios we partner with.
No — we're not an industrial design studio. If you need concept design, sketching, or brand-level product design, bring your own designer or studio and we'll work directly with them from day one — or, if you don't have one yet, we can introduce you to one of the design studios we partner with. What we do is take an existing CAD file — yours or theirs — and engineer it for manufacturability, cost and process fit.
People who make parts for a living: our own engineers, mold makers and industrial designers. They don't redraw your product — they guide it: flagging what will fail in the chosen process, what will cost more than it needs to, and which small geometry changes get the best possible result. Through it all, one engineer stays your single point of contact from quote to production.
That's fine — rough is a normal starting point. An engineer looks it over at whatever stage it's at and flags what needs to firm up before it can be accurately quoted, rather than requiring a finished, production-ready file upfront.
That's one of the most common jobs here. A file that prints cleanly usually can't be molded as drawn — no draft angles, uneven walls, undercuts a mold can't release — but it doesn't need redesigning from scratch. It needs an engineering pass: draft added, walls made uniform, solid sections turned into ribs. You see every change and its cost impact before any tooling is cut, and the part keeps working and looking the way you designed it. The same applies to any process switch — the concept stays yours; the geometry gets engineered for the process that'll actually run it.
Every order includes a DFM pass on the parts being made, once the quote is approved. This capability goes further: reviewing a whole product or assembly for consolidation, material strategy and cost-down opportunities across multiple parts, not just checking one part's tolerances.
Yes — if your product was designed by an outside studio, we coordinate manufacturability directly with them rather than relaying feedback through you. Their design intent and our production constraints get resolved directly, not lost between two separate conversations.
Only if you want it to. Every recommendation comes with its cost impact shown, so you decide what to keep as-is for looks or brand reasons and what to simplify for cost — nothing gets changed without you seeing the tradeoff first.
No — the DFM pass that follows an approved quote is included on every order, the same as any other process. A deeper, whole-product review — consolidating multiple parts or rethinking material strategy across an assembly — is scoped with your engineer based on what's actually involved, not a fixed add-on fee.
Then it needs an industrial designer — and we'll say so rather than take on work outside what we're good at. But you're not left on your own: our engineers, mold makers and industrial designers will guide you on what the design has to hit to manufacture well — process, material, cost targets — and we can introduce you to one of the design studios we partner with. Once the concept exists, the same engineer picks the file back up and takes it through quoting and production.
