AI-Powered supplier vetting

SummaryLongran Electromechanical (Zhejiang) Co., Ltd. is a Chinese manufacturer/factory producing electric motors and related motor-control products. It reports substantial annual production across single-phase, three-phase, and DC motors, export licensing, export sales activity, and customization, 3D design, ODM, and recent new-product development capabilities. However, its service-control procedures and finished-product inspection instructions lack written records, and it reports no in-stock service, overseas warehouse, overseas showroom, or valid manufacturing-capacity contract with affiliated subcontractors. An SGS audit is identified, but the stated report validity ended on 2025-03-19, so current certification or audit validity cannot be confirmed. Financial credibility and customer-case strength remain insufficiently evidenced.

Supplier typeThe supplier is identified as a limited company and manufacturer/factory based in Zhejiang, China, with a business scope covering electric motors, motor-control systems, related components, and R&D. It also has affiliated companies and a valid import/export license, supporting its classification as an operating manufacturing supplier.

R&D capabilityThe supplier reports R&D for motors and control systems, new products within the past year, 3D software design services, and ODM availability. It does not provide an SDK, but that limitation does not negate the directly stated product-development and design capabilities.

Production capacityReported annual capacity is 110,000 single-phase motors, 160,000 three-phase motors, and 40,000 DC motors, supported by assembly and painting lines. The supplier also states peak- and off-season lead times within 15 workdays and holds an import/export license; however, it lacks in-stock capability and has no valid contract with affiliated subcontractors, so the positive assessment is based on stated factory capacity rather than fully documented production controls.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full and minor customization, flexible customization, 3D software design services, and ODM services. These multiple stated service types provide direct evidence of broad customization capability.
