SummaryNingbo Derry E&M Tech Co., Ltd. is a China-based limited company established in 2017 and located in Ningbo, Zhejiang. It operates in motor and gear-motor products, with stated production of DC and AC motors, five production lines, 130 employees, and export activity since 2018. The supplier reports ISO9001, IATF16949, ISO14001, RoHS, and CE credentials, with some products UL approved. It states that it provides R&D and customization services, has 18 years of total R&D-engineer experience, and serves domestic and multiple overseas markets. Evidence is insufficient to assess after-sales service, financial credibility, or customer cases. The supplied information also identifies the company as a trade company, while other descriptions present it as a manufacturer, so its precise operating role should be verified.

CertificationsThe supplier states that it has passed ISO9001, IATF16949, and ISO14001 quality or management system certifications authorized by the German TUV group. It also states that all products are RoHS compliant and CE certified, with some products UL approved. These claims provide explicit evidence of substantial certification coverage, although certificate validity and scope are not independently documented in the slices.

R&D capabilityThe supplier explicitly states that it emphasizes innovation and provides motor manufacturing and R&D services. It reports 18 years of total R&D-engineer experience, access to advanced technology and equipment, and products featuring variable-frequency-drive control, precise speed control, low vibration, and application-oriented designs. These statements support an innovation capability assessment, though no patents or independently verified development outcomes are provided.

Production capacityThe supplier offers multiple motor and gear-motor categories and reports 50,000,000 DC-motor pieces and 30,000,000 AC-motor pieces of annual production, five production lines, 130 employees, and 10 total staff experience. It also states that peak- and off-peak order fulfillment each require one month. The stated output and production infrastructure provide explicit evidence of production capability.

Customization capabilityThe supplier explicitly states that it offers customization to meet specific customer requirements and provides multiple sizes and power ratings. Its product range includes DC, AC, brushless, stepping, worm-gear, and other motors, while its R&D and manufacturing positioning supports technical adaptation. The slices do not define customization limits, engineering procedures, or minimum order conditions.
