AI-Powered supplier vetting

SummaryNINGBO TONGYI METALWORK CO., LTD. is identified as a Chinese manufacturer/factory specializing in architectural hardware, kitchen accessories, furniture hardware, and related metal components. It reports ISO 9001 certification, five production lines, 11–20 quality-control staff, modern machinery, precision testing equipment, and automated production lines. The supplier has exported since 1998, reports 90% export sales, and serves broad global markets through Ningbo port. Its stated capabilities include standard and custom manufacturing, while its R&D engineering experience is under five years, providing only limited evidence of deep technical development capacity. Two trade records associate the company with Electrolux Professional Inc. and JELD WEN, but each record shows only one transaction, so customer depth cannot be established. After-sales capability and financial credibility are not sufficiently evidenced.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory in China and describes itself as a specialized manufacturer of architectural hardware and kitchen equipment accessories, including locks, pulls, latches, drains, hooks, and related products.

CertificationsThe supplier explicitly reports holding ISO 9001 certification and describes a structured quality-management approach covering production and inspection. This provides direct evidence of a formal quality-management certification.

R&D capabilityThe supplier reports modern machinery, precision testing equipment, automated production lines, and an R&D team developing new and improved products. However, the stated total experience of R&D engineers is under five years, so the evidence supports active innovation capability but not extensive R&D maturity.

Production capacityThe supplier reports five production lines, 11–20 quality-control staff, modern machinery, automated production lines, and nearly 30 years of manufacturing experience. It also states that it supports standard and custom manufacturing across architectural hardware and kitchen accessories, indicating established production resources.

Customization capabilityThe supplier explicitly states that its equipment supports both standard and custom manufacturing and that it provides tailored solutions for architectural fittings, stainless steel parts, and commercial kitchen accessories. This is direct evidence of customization capability.

Client casesThe supplier states that it has served clients across Europe, North America, and Asia, and trade records associate it with Electrolux Professional Inc. and JELD WEN. However, each listed trade record contains only one transaction, so the breadth and continuity of these customer relationships cannot be confirmed.
