My model looks great on screen, but factories say it can't be made.
We make your model manufacturable.
We repair broken meshes, thin walls and undercuts for casting, keep your look, and you approve before any mold is cut.
For designers, studios and makers with a 3D model
Your 3D model,
made in metal.
Send your 3D file, whether it comes from CAD, ZBrush, Blender or an AI tool. We fix what won't cast, make the molds and deliver finished pieces. Samples about 6 weeks after file approval, runs from 500 pieces.

Why people come to us
Making it in China shouldn't feel like a gamble.
A 3D model on screen is not yet a part a factory can cast. These are the four things we hear most, and how we handle each one.
The sample came back wrong, and every fix costs another month.
We get it right before the mold.
We flag casting and plating problems on screen, and one English-speaking project manager sends photos at every stage.
I have an STL, but the factory wants STEP files and tolerances.
Send what you have. We prepare the production files.
STL, OBJ, ZBrush or CAD: we set the parting line and tolerances so the molds are cut right the first time.
I'm worried my design ends up being sold by someone else.
Your design stays yours, on paper.
NDA before you send files. Molds carry your project number, belong to you, and stay with us only under a custody agreement.

Casting, stamping or engraving, which metal, and which finishes suit your design.
3
A price range
A rough cost per piece at 500 and more, plus the one-off mold cost.
4
A realistic timeline
How long until samples, and until finished goods arrive.

What files can I send?
STL, OBJ, 3MF, STEP/STP, IGES, ZBrush and Blender files all work, including models made with AI tools. If you're unsure, send what you have and we'll tell you.
Is the manufacturability check really free?
Yes. Send your 3D file and within 2 business days you get a clear answer on whether it can be cast, what needs fixing, a price range and a timeline. There is no obligation to go ahead.
What's the smallest order?
500 pieces per design. The mold is a one-off cost, so the unit price drops as quantity grows, and reorders need no new tooling.
How long until I see samples?
About 6 weeks from an approved 3D model: roughly 4 weeks to engrave the molds, a week to tune them and a week for finishing. You get photos at each stage.
Who owns the molds?
You do. Ownership is written into your contract before tooling starts. We store the molds for you under a custody agreement, use them only for your orders, and send you photos of the marked molds.
Can you work with AI-generated models?
Yes, and many of our clients start there. AI models usually need repair before casting: closing the mesh, thickening thin areas and adding draft. We do that while keeping the look you designed.
I only have a sketch. Can you still help?
Yes, as a separate paid modeling service. We quote the modeling up front, and once you approve the 3D model the project continues as normal.
Can you sign my NDA instead?
Yes. Send yours and we'll review and sign it before you share files.
Do you work with clients outside China?
That's who we work for. We ship by air or sea to you, your warehouse or your fulfillment partner, with updates in English throughout.
