AI-Powered supplier vetting

SummaryDalian Doopool Metal Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, offering clutch pulleys. It reports professional technical supplier and customization capabilities, including sample-, design-, minor-, flexible-, and full-customization services. The supplier holds TS 16949 certification and operates three production lines, with 11–20 quality-control staff and 6–10 years of total R&D engineer experience. However, the information states that it has no 3D software design, ODM, OEM for popular brands, SDK, in-stock, overseas warehouse, overseas showroom, overseas agent or branch, and no offline trade-show participation. Complaint handling and corrective/preventive-action procedures exist but lack written records. Financial information is insufficient for a credibility assessment, and customer information only indicates stable cooperation with customers in the United States, Europe, Japan, and China without named cases.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, legally structured as a limited company in China. Its stated product scope is clutch pulleys, but the business-scope entry is incomplete, so the full scope cannot be determined.

CertificationsThe supplier reports holding TS 16949 certification. This is explicit evidence of a formal supplier management-system certification.

After-Sales capabilityThe supplier has a customer-complaint procedure and a corrective/preventive-action procedure, but neither has written records. It also reports no in-stock service, overseas warehouse, overseas showroom, overseas agent or branch, and no offline trade-show participation, indicating limited documented and overseas service infrastructure.

R&D capabilityThe supplier is identified as a professional technical supplier and has R&D engineers with 6–10 years of total experience. However, it reports no new products in the past year, no ODM service, no SDK, and no 3D software design capability, so the evidence shows technical capability but limited recent innovation and software-related development.

Production capacityThe supplier is identified as a manufacturer/factory operating three production lines, with 11–20 quality-control staff, and is located in Wafangdian, Dalian. It also reports an annual production-output category, but the stated employee count is only 7 and the broader production scale is not fully reconciled, so production capability is supported but should be verified.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, flexible customization, and full customization. This directly supports broad customization capability, although it does not include 3D software design services.
