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 has ISO9001 quality management system certification and nearly 20 years of cutting-tool design and manufacturing experience. It supports extensive customization and OEM services for popular brands. However, quality-control resources and documentation appear limited: it reports fewer than five quality-control staff, one inspector, no quality assurance, and inspection, corrective-action, and complaint procedures without written records. Export experience is limited to one year, with exports representing 1%–10% of sales. Financial, environmental, fire-drill, customer-case, and SDK evidence is insufficient for a positive assessment.

Supplier typeThe supplier is CHANGZHOU WEIYU TOOLS FACTORY, a China-based limited company established in 2004, operating independently rather than as part of a larger group. Its stated product scope is carbide end mills and carbide drills, with a broader description covering precision and customized cutting tools.

CertificationsThe supplier states that it has passed ISO9001 quality management system certification. However, another slice explicitly reports no quality assurance in quality-control processes, so the available evidence supports certification holding but also indicates weaknesses in implementation or documentation.

Production capacityThe supplier operates one production line with 18 total employees and reports annual output of 40,000 solid carbide end mills and 30,000 carbide drills. Its listed equipment covers CNC machining, grinding, laser marking, lathing, and notch grinding. Capacity controls are limited because it does not conduct ongoing batch quantity reconciliation and has no outsourcing SOP.

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