AI-Powered supplier vetting

SummaryQiankun Tech demonstrates integrated R&D, design, manufacturing, sales, installation, and after-sales capabilities. It supports extensive customization, ODM, OEM for known brands, documented R&D and quality procedures, and maintains ISO9001:2015 and ISO14001:2015 certifications alongside other stated certifications. Manufacturing assets include laser cutting, machining, drilling, grinding, and welding equipment, with finished-product inspection instructions and supplier-control procedures. The supplier has export experience, including a high stated export-sales proportion, but lacks overseas branches, agents, warehouses, and showrooms. Financial information is insufficient for assessing credibility, while innovation evidence includes new products, five patents, and one national science and technology progress award. Customer-specific case details are not provided.

Supplier typeThe supplier presents itself as a diversified industrial group and an integrated high-tech enterprise covering R&D, design, production, sales, installation, and after-sales service. Its disclosed equipment and export activity support classification as a manufacturing-oriented industrial supplier.

CertificationsThe supplier explicitly holds ISO9001:2015 and ISO14001:2015 certificates, and also states OHSAS18001, Intellectual Property Standardization, CCPIT Export Commodity Brand, and TÜV Rheinland certifications. The slices do not provide validity dates or scope details for every certification, but the stated certification portfolio is substantive.

After-Sales capabilityThe supplier states that it integrates installation and after-sales service, has a clear customer-complaint procedure with follow-up records, and maintains quality assurance. However, no response-time, service-team size, warranty, or geographic coverage details are provided.

R&D capabilityEvidence includes new products during the past year, ODM capability, five R&D patents, one national science and technology progress award, documented design input/output, review, verification, and validation records, and use of CAD, Photoshop, SolidWorks, and 3D-Max. The supplier also reports R&D engineers responsible for new-product development and customer customization.

Production capacityThe supplier reports laser cutting, horizontal lathe, radial drilling, grinding, and welding equipment; standardized finished-product inspection instructions; valid manufacturing contracts with associated subcontractors; inventory capability; and documented supplier assessment and corrective-action procedures. It lacks overseas warehouse capability, but that is a logistics limitation rather than evidence of inadequate production capacity.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, and states that R&D engineers develop products according to customer needs. ODM availability and documented design-control records further support its customization capability.
