Independent designers
Product designers and industrial design studios with a closure idea and a sketch.
누구를 위한가
Four kinds of project.
Startups and small brands
Early companies, including crowdfunding projects, that need engineering and a factory behind the idea.
Small manufacturers
Teams who already make a product and want a rotary closure added to it.
Schools and maker teams
Studios, labs and student teams. Each project is reviewed on its own.

What we do on a project.
| Capability | What we do |
|---|---|
| Engineering | We review whether the idea can work, choose the dial, lace and guide path, and design the mechanics. |
| Rapid prototypes | Printed or bench-made models, then a sample that opens, closes and holds. |
| Tooling | A dedicated tool, or an existing platform reused so the first version costs less. |
| Testing | Life, tension and environment checks on the closure. Results belong to the project. |
| Short runs | A smaller first batch so an early product can ship before a large order makes sense. |
| Production | Scaled manufacturing, inspection and export packing when the product is ready. |
Process
From a sketch to a first run.
- 01
Submit
Fill in the form and upload a sketch. If you need it, we sign an NDA before you send confidential detail.
- 02
Review
Engineering reviews feasibility and writes back with the project.
- 03
Scope
We send a construction proposal and how we would work together. Price and timing are quoted for that project.
- 04
Prototype
We build a functional sample. You test it. We revise it.
- 05
Tooling & test
Tools are cut, then reliability tests are run.
- 06
Launch
A short run first, then volume when you ask for it.

Directions, not a catalog.
These are places a rotary dial might go. They are not products already in the line.
Questions
Will my idea be protected?
You can sign an NDA before we look at confidential detail. Only people assigned to the project should see your files. At the concept stage, send a non-confidential summary — the form asks for that, and nothing more.
Who owns the IP?
Design patents on the dials are filed under 浠珀适（深圳）科技有限公司. The utility-model patent is under 东莞市金胜模具塑胶有限公司 (Jinsheng Molding). Patent numbers are not published here. Anything new that a co-development creates is a contract question. This page is not legal advice.
What does it cost, and what is the minimum?
We quote fees, minimums, and any royalty with the project. This site does not list them.
How long does it take?
Timing is quoted with the project. We do not reuse day counts from older sales sheets.
Do you sell to end consumers?
No. The product launches under your brand. supfit handles engineering and manufacturing. This website does not sell finished goods.
Submit
Tell us the idea. Leave the secrets out.
At the summary stage, do not include confidential information. Exchange drawings after an NDA is signed. NDA and co-development agreements still need a lawyer — background IP, new IP, exclusivity and territory are contract terms, not website copy.
Helmets and medical products can require their own certifications. We will flag that in review. This note is not legal advice. We keep the time of each submission so later disputes about who showed what are easier to untangle.
