AI-Powered supplier vetting

SummaryWenzhou Winner Hardware Co., Ltd. is identified primarily as a Chinese manufacturer/factory producing locks, lock bodies, cylinders, handles, hinges, and related hardware. Its documented production includes two lines and annual capacities of 100,000 sets each for mortise locks and mortise lock bodies, plus 50,000 door locks. The supplier reports ISO 9001 certification, while many products reportedly hold CCC and CE certifications. It has experienced technical and R&D personnel, six to ten quality-control staff, export sales representing 51%–70% of total sales, and established export coverage across multiple regions. Lead times are stated as one month off-season and two to three months during peak season. Evidence is insufficient to confirm after-sales service systems, financial credibility, customization execution, or specific customer cases.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and is described as designing, developing, producing, and selling hardware products. However, one record separately labels the company nature as a trading company, creating a classification inconsistency despite the stronger manufacturer-specific descriptions and factory address.

CertificationsThe supplier reports ISO 9001/ISO9001-2015 certification, and states that many products have passed national CCC compulsory certification and EU CE certification. These statements provide explicit evidence of management-system certification and product certifications, although the records do not identify the specific certified models or certificate validity dates.

R&D capabilityThe supplier explicitly describes its technical team as experienced in locking and states that it specializes in design and development. It also reports six to ten years of total R&D engineer experience and identifies innovation as part of its development strategy, supporting a positive indication of technical and innovation capability.

Production capacityThe supplier reports two production lines and annual capacities of 100,000 sets for mortise locks, 100,000 sets for mortise lock bodies, and 50,000 sets for door locks. It also reports six to ten quality-control staff, one-month off-season lead time, and two-to-three-month peak-season fulfillment, providing explicit evidence of established production operations.
