Smart wearables, ready to stock or built around your brand.

EngraSun is the smart wearable brand of Shenzhen Mingyang Industrial Development Co., Ltd, established in Shenzhen in June 2019. We operate our own around 1,000 m² assembly facility with about 50 people and a monthly capacity of around 30,000 units. Sales, engineering coordination and quality control are managed in-house, so your project is handled by one accountable team from design to delivery.

We support the full process: industrial design (ID), mechanical and structural design, hardware development, firmware and software development, custom companion apps, product assembly and mass production. Standard customization includes laser-engraved logos, body and strap colours, strap materials, boot logos, packaging, manuals and certification assistance. Selected models support a white-label app, including the TK20 smart ring; for other models white-label apps are available on request.

Yes. Every model shown on this website is available as a standard catalog product for wholesale and distribution orders, with mixed-model ordering and accessory bundling. The same models also support private-label OEM/ODM if you later want laser-engraved logos, custom colours, packaging or a white-label app. Tell us the models and quantities you need and we will confirm pricing, MOQ and lead time.

MOQ depends on the model and on the level of customization. Orders based on existing models with logo and packaging customization start at a lower quantity, while projects with custom industrial design, new tooling or bespoke firmware require higher volumes. Tell us the model, target market, customization level and expected quantities, and we will confirm the MOQ in our quotation.

Yes — private-label and own-brand programs are our main business. EngraSun itself is registered in China, the United States and the European Union, and we routinely build products under customer trademarks: laser-engraved branding on the body, clasp or case, custom boot logos, branded packaging and multi-language manuals. Our existing brand customers have been working with us for more than four years.

Our certification scope covers CE, FCC, RoHS and TELEC, and we ship to customers worldwide — including established programs in Europe, Japan and other regions. We provide certification documentation and certification-assistance services for OEM orders; the exact certifications applicable to each model and destination market are confirmed at quotation.

Timing depends on customization depth. Projects based on existing models with logo and packaging customization move fastest; projects with custom ID, new tooling, bespoke firmware or a white-label app include design, prototyping and pilot-production stages. A detailed schedule with sampling and mass-production dates is included in every proposal after specifications are confirmed.

EngraSun works B2B only. Unit price depends on the model, customization scope, order quantity, certification requirements and shipping terms, so list prices would be misleading. Use the inquiry form or contact info@mysyfz.com to receive a quotation built around your actual requirements.

No. Our smart watches, bracelets and rings are general wellness and lifestyle devices. Readings such as heart rate, blood pressure trend, blood glucose trend, SpO2 and ECG heart-rhythm recordings are consumer-level estimates for fitness and wellness reference only; they are not medical measurements and cannot diagnose, treat, cure or prevent any disease. Marketing materials and app interfaces for your project should keep this wellness framing.

Only three current models carry genuine AI features: the MW09 AI watch, the W100 AI translation glasses and the MSPG007 Ultra AI camera glasses. Their AI functions run through a connected phone app, and voice or images are captured only when the user activates the feature. Camera glasses include a recording indicator. For programs in regions with strict privacy regulation (such as GDPR in the EU) we support aligned privacy documentation, and AI service providers and wake words can be discussed for OEM projects.

Send an inquiry through the contact page with your target market, business type, models of interest, expected quantities and customization needs. We typically respond by email or WhatsApp, then confirm specifications, customization options, certification requirements, sampling and a quotation.
