AI-Powered supplier vetting
SummaryThe supplier operates in transmission, micro-motor and component sales, motor control-system development, design services, electronic products, molds, and import/export activities. It provides ODM and broad customization services, but reported no new products in the past year and has no available SDK. Production is supported by CNC compaction technology, with 6–10 quality-control staff and a stated annual output range; however, the number of R&D engineers is listed as 1. Quality-system evidence is incomplete: procedures for corrective actions and complaints exist but lack written records, while testing equipment is listed as 0 and traceability status is unknown. Financial records are identified for 2021–2023, but their results are not provided. The supplier reports exports to customers in multiple regions, although overseas service infrastructure is absent.
Supplier typeThe supplier is a manufacturer and service provider covering micro motors, components, motor control-system development, precision metal parts, molds, design services, and trading activities. Its description specifically references MIM parts and CNC compaction technology, indicating an industrial component-oriented supplier profile.
Production capacityProduction evidence includes CNC compaction technology, MIM-part application experience, a stated annual production-output range, and 6–10 quality-control staff. However, quality-control test equipment is listed as 0, so production scale is documented but quality-control readiness presents a clear deficiency.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also provides ODM services. This directly supports a broad customization capability.
Client casesThe supplier states that it has served metal-parts customers from Europe, Canada, the United States, Brazil, Russia, Japan, and China. These are geographic customer references, but no customer names, project details, or independently verifiable case studies are provided.
