Dongguan Mingmei Electronics Co., Ltd was registered in 2019. The know-how behind it is older — our family has been trading scales for over 20 years. We are specialized in designing, manufacturing and selling electronic weighing instrument.

Our main products are Jewelry scales, kitchen scales & coffee scales, etc.

We take innovation & creation as the greatest core competitiveness, and have obtained a certain number of intellectual property patent. And we're keeping on our innovation. Our aim is to design more and more classic and popular products.

And we always insist on precising quality management system, improving produce technology, make sure every single scale is outstanding performance before ship out.

Own Design & Tooling

We do not buy public-mold housings and put a logo on them. Our private models start on our designers' screens: structure drawings, 3D printed prototypes, then tooling drawn by us and trial-shot at the molder who has run our molds for years.

Structure design: CAD drawing of a private-mold scale

3D printed prototypes - fit and function check before tooling

Mold trial: first shots from our own tooling

Design Patents

Our jewelry, kitchen and pet scale designs hold granted Chinese design patents - 7 of them, granted by CNIPA between 2023 and 2026. Certificate numbers are verifiable: ask us for the full certificate of any model you quote.

Inside Our Factory

Assembly, calibration and 100% testing in our own workshop; injection at a long-standing partner — the tooling is ours.

Who we ship to. Buyers in the United States, Canada, the EU, the UK and Australia — importers, brand owners, marketplace sellers and coffee equipment specialists. Jewelry scales remain our deepest line; coffee and kitchen scales are where most of the private-mold work now comes from.

Documents follow the destination: CE-EMC and RoHS for the EU and UK, FCC Part 15B SDoC for the US — already in hand for 33 models — food-contact reports for every platform that touches food. Where a market needs a test we do not yet hold for your model, we arrange it before production and quote it up front — not after the container is booked. Which certificates each market needs, and how we protect a territory.

Notes from the founder

I started in this trade in 2019, selling scales for a family business on commission — no salary, no safety net, just the products and my word. Within a year, demand outgrew that capacity, and we opened our own factory.

My first mold was a disaster. A kitchen scale for a client that could not carry the 10 kg it promised. Nobody taught me structure, so I bought a stack of other people’s scales, took them apart, and worked out why theirs held and mine didn’t. The second mold opened clean — that model is still one of our best sellers. Seven design patents later, the habit hasn’t changed: I still test past the rating, and I still refuse to print a number I can’t stand behind.

We keep one line, and the molds are ours — drawn, paid for and signed off here. Not because we couldn’t grow faster, but because I’d rather know every batch that leaves here. If you’re a brand that needs something not already on every shelf — that’s the part of this job I like.
