AI-Powered supplier vetting

SummaryNingbo Yinzhou Ke Ming Machinery Manufacturing Co., Ltd. is a China-based limited company in Zhejiang, described as both a trading company and an industry-and-trade business. The supplier reports casting, machining, and forging production capacity, exports accounting for 90% of sales, and export experience since 2015. Its descriptions cite more than ten years of factory experience, customers in multiple overseas countries, ISO9001:2008 quality-control claims, and tolerance capability of ±0.01 mm, although these claims are supplier-provided and not independently confirmed in the provided data. Product coverage includes casting, forging, stamping, welding, and machining parts. An SGS audit is listed, but the audit result is coded as 0 and the report validity ended on 2025-04-14; the meaning of the result code is not provided. Evidence is insufficient to assess after-sales service, financial credibility, or innovation capability.

Supplier typeThe supplier is identified as a limited company from China and is classified as a trade company. Its own description further characterizes the business as industry-and-trade, indicating combined manufacturing and distribution activities rather than a purely manufacturing-only profile.

Production capacityThe supplier reports annual capacity of 8,000 tons for casting parts, 2,000 tons for machining parts, and 2,000 tons for forging parts. Its stated product range covers precision, lost foam, sand and die casting, forging, stamping, welding, and machining, while reported lead times are within 15 working days in both peak and off-peak periods; these figures are supplier-provided.

Customization capabilityThe supplier describes production to customer requirements, R&D and design support, and a broad range of metal-processing methods. It also claims tolerance capability of ±0.01 mm, but the available evidence does not specify the applicable products, testing basis, or independent verification.

Client casesThe supplier reports customers from Germany, the United States, Canada, Sweden, Israel, Hungary, Mexico, and Guyana, and reports 90% of sales from exports. These are supplier-provided market claims; no named customer references, order examples, or independently verified case studies are included.
