AI-Powered supplier vetting

SummaryCHANGZHOU WEIYU TOOLS FACTORY is a China-based limited company established in 2004 with 18 employees and one production line. It supplies carbide end mills and carbide drills, reporting annual output of 40,000 solid carbide end mills and 30,000 carbide drills. The supplier states that it holds ISO9001 certification and offers extensive customization, including design- and sample-based customization. It also reports OEM service for popular brands. However, quality assurance is explicitly indicated as unavailable, finished-product inspection has instructions but no written records, and complaint-handling and corrective-action procedures lack written records. R&D resources are limited to one engineer, with no SDK availability. Export experience is limited, with exports representing 1%–10% of sales and beginning one year ago. Financial and sustainability-related evidence is insufficient for a firm assessment.

Supplier typeThe supplier is CHANGZHOU WEIYU TOOLS FACTORY, a China-based limited company operating in Jiangsu and established in 2004. It is not part of a larger company group and specializes in carbide cutting tools, particularly carbide end mills and carbide drills.

CertificationsThe supplier states that it has passed ISO9001 quality management system certification. However, the quality-control assessment separately states that quality assurance is not available, so the evidence supports certification holding but also indicates weaknesses in practical quality-assurance implementation.

Production capacityThe supplier operates one production line and reports annual output of 40,000 solid carbide end mills and 30,000 carbide drills, supported by CNC, grinding, laser-marking, lathe, and notch-grinding equipment. However, it does not conduct ongoing quantity reconciliation for batches and has no standard operating procedure for outsourced manufacturing, indicating production-control weaknesses.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its product description also states that it produces specially customized cutting tools, providing direct evidence of broad customization capability.
