AI-Powered supplier vetting
SummaryThe supplier demonstrates customization, ODM, and R&D activity, including new products within the past year. It has one production line, specified spring-manufacturing equipment, three quality inspectors, standardized finished-product inspection instructions, and 25 years of export experience. However, its service-management procedures lack documented records, and it reports no overseas warehouses, showrooms, agents or branches, or offline trade-show participation. The supplier holds an ISO9001:2015 certificate, but no factory environmental impact assessment report and no regular fire drills in the past year are reported. Financial information is insufficient for a meaningful assessment. No OEM service for popular brands, SDK availability, or customer cases is evidenced.
Supplier typeThe supplier has manufacturing-related equipment for torsion and compression springs, hardening and grinding, one production line, and offers ODM services. Its profile therefore supports classification as a manufacturer with design and customization capability, although the slices do not provide a formal supplier-type label.
CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit certification evidence, although the same slice reports no factory environmental impact assessment report and no regular fire drills during the past year.
R&D capabilityThe supplier reports new products within the past year, R&D capability, and ODM services, which support active product-development capability. However, it has no available SDK and does not provide OEM services for popular brands; these limitations do not negate the stated R&D capability.
Production capacityProduction evidence includes dedicated spring machinery, one production line, three quality inspectors, standardized finished-product inspection instructions, and one-month average lead times in both peak and off-season periods. However, the factory does not continuously reconcile quantities for each batch or mass-production run, so production-control coverage is incomplete.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and design-service information.
