AI-Powered supplier vetting

SummaryThe supplier is a privately owned combined business and manufacturer of springs and related elastic components, established in 2015 and exporting for 9 years. It reports ISO9001:2015 certification, documented finished-product inspection procedures, automated production equipment, and broad customization supported by R&D and 3D design services. Reported lead time is within 15 working days in both peak and off seasons. Limitations include no SDK, no factory environmental impact assessment report, no valid manufacturing-capacity contract with affiliated subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no overseas service countries reported. The supplier has one R&D engineer and no Fortune 500 customer collaborations disclosed.

Supplier typeThe supplier is identified as a privately owned combined company whose scope includes spring and hardware-accessory manufacturing and processing. Its product range covers compression, torsion, extension, battery, profiled, and other steel-wire springs and elastic components; the company description also identifies it as a spring manufacturer established in 2015.

CertificationsThe supplier reports holding an ISO9001:2015 certificate, and the certification is stated consistently in the management-system and sustainable-development information. This provides explicit evidence of a quality-management certification, although no other certification is listed.

R&D capabilityThe supplier identifies itself as a professional technical supplier, provides 3D software design services, and supports customization from samples, designs, and other formats. However, it has no available SDK and reports only one R&D engineer, so the evidence supports design capability but not a broad or highly developed innovation infrastructure.

Production capacityThe supplier manufactures multiple spring and steel-wire product categories, uses multiple automated production equipment, follows written and uniform finished-product inspection instructions, and reports lead times within 15 working days in both peak and off seasons. Constraints include no inventory capability and no valid contract with affiliated subcontractors, which limits evidence of broader capacity support.

Customization capabilityThe supplier explicitly offers customization from samples, designs, minor customization, flexible customization, and full customization. These options are supported by reported R&D capability and 3D software design services, providing clear evidence of broad customization coverage.
