AI-Powered supplier vetting

SummaryThe supplier manufactures and sells springs, machine parts, and related mechanical components, with production equipment covering forming, compression and extension spring manufacturing, heat treatment, grinding, stamping, tapping, packing, and other processes. It reports customization from samples, designs, and full customization, supported by a stated design capability. Quality-related evidence includes three QA/QC inspectors, ISO9001:2015 certification, quality assurance, and documented corrective-action and complaint-handling procedures. The supplier has in-stock capacity and stated one-month lead times in both peak and off-season periods. However, it reports no valid manufacturing-capacity contract with affiliated subcontractors, no overseas warehouse, overseas branch or agent, showroom, or offline trade-show participation. No OEM service for popular brands, SDK availability, or customer cases is evidenced.

Supplier typeThe supplier is a manufacturer and seller of springs, machine parts, spare parts, and general-purpose components. Its stated factory operations include production workshops, specialized equipment, and direct manufacturing activities, indicating a manufacturing-oriented supplier rather than only a trading entity.

CertificationsThe supplier holds an ISO9001:2015 certificate and also reports a sustainable development management system certification associated with that certificate. This is explicit evidence of a formal quality-management certification.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints and corrective/preventive actions, supporting a formal after-sales response process. However, it has no overseas agents or branches, overseas warehouse, or showroom, so overseas service reach is limited.

Production capacityProduction capability is supported by extensive listed equipment, production workshops, more than 60 employees, nearly 100 automatic production machines, in-stock capacity, 85 qualified service-capability suppliers, and one-month peak and off-season lead times. A limitation is that no valid manufacturing-capacity contract exists with affiliated subcontractors, which leaves subcontracted capacity governance unclear.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, and full customization. Its spring and machine-part manufacturing scope further supports the relevance of these customization services to its stated products.
