AI-Powered supplier vetting

SummaryChangzhou SDK Precision Technology Co., Ltd. is identified as a trade company in Changzhou, offering carbide end mills and related technical, metal-tool, parts, and materials businesses. It reports professional technical R&D capability, one R&D engineer, six to ten quality-control staff, new products launched in the past year, and customization from samples, designs, or full specifications. Reported production information includes 800,000 carbide standard end mills annually, with off-peak lead time within 15 workdays and export markets in South America, Southeast Asia/Mideast, and Europe. Limitations include no 3D software design, ODM, SDK, popular-brand OEM, overseas showroom, overseas agents or branches, or offline trade-show participation. The provided materials do not establish certification holding, reliable after-sales procedures, financial strength, or customer cases. The audit record identifies TÜV Rheinland, but the audit result is recorded as 0 and no certification conclusion is provided.

Supplier typeThe supplier is classified as a trade company located in Changzhou, with business activities covering technical services and development, metal tools, mechanical parts, metal materials, hardware, and ceramic products. Its primary product is identified as carbide end mills, indicating a trading and technical-supply profile rather than a clearly documented manufacturing-only entity.

After-Sales capabilityThe supplier has no overseas showroom, overseas agents or branches, or recorded offline trade-show participation, and reports service coverage in zero countries. Its complaint-handling and corrective/preventive-action mechanisms have no written procedures or records, which is explicit evidence of a service-process deficiency.

R&D capabilityThe supplier is identified as a professional technical supplier with R&D capability, one R&D engineer, and new products launched during the past year. Nevertheless, it does not provide 3D software design, ODM, SDK, or popular-brand OEM services, showing some defined capability limits.

Production capacityThe supplier reports annual output of 800,000 carbide standard end mills, six to ten quality-control staff, and an off-peak lead time within 15 workdays. These explicit capacity and delivery figures support production capability for the stated product, although the company is also classified as a trade company.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. The same customization range is reported in two slices, providing direct evidence of broad customization availability.
