AI-Powered supplier vetting

SummaryWenzhou Jiangdun Metal Co., Ltd. is a China-based limited company established in 2021, offering springs, mold accessories, guide pillars and sleeves, thimbles, and punching needles. It reports ISO9001:2015 certification, more than 10 production lines, 41–50 quality-control staff, and stated lead times within 15 working days in both peak and off-peak periods. The supplier exports to South America, Southeast Asia/Mideast, and Europe, but began exporting only in 2024 and reports exports as 1%–10% of total sales. Several important capabilities—including outsourcing procedures, inventory services, overseas facilities, R&D services, OEM/ODM, traceability, and customer cases—are marked unknown. An SGS audit record is available for the period from May 17, 2025 to May 16, 2026, but the stated evaluation result is not interpretable from the provided value alone.

Supplier typeThe supplier is identified as Wenzhou Jiangdun Metal Co., Ltd., a China-based limited company in Zhejiang, with a combined company/business-entity type. Its listed products are springs, mold accessories, guide pillars and sleeves, thimbles, and punching needles, indicating a manufacturing-oriented industrial component supplier.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate. An SGS audit record is also listed with validity from May 17, 2025 to May 16, 2026, although the audit result value is not sufficiently explained to assess the outcome.

After-Sales capabilityThe company description claims a complete after-sales service system. However, the available records mark in-stock service, overseas warehouse capability, and overseas showroom capability as unknown, so the scope and operational strength of after-sales support cannot be verified.

Production capacityThe supplier reports advanced production technology, sophisticated processing equipment, precise testing instruments, more than 10 production lines, and 41–50 quality-control staff. It also states lead times within 15 working days during both peak and off-peak seasons, providing explicit evidence of substantial stated production capacity.
