AI-Powered supplier vetting
SummaryThe supplier is identified as a professional automatic-door technology manufacturer offering 3D design, ODM, OEM, SDK, and sample-based customization services. It reports quality assurance, raw-material traceability, standardized finished-product inspection, valid manufacturing contracts with associated subcontractors, and an automatic-door output of 7,722 sets. However, it reports no new products in the past year, no written corrective/preventive-action records, no inventory, overseas warehouse, overseas agents, branches, or showroom, and no offline trade-show participation. Financial evidence is limited to references to records for 2022–2024, without substantive financial results. Certification claims include ISO9001, ISO14001, SGS, and CE in the company description, but supporting certificate details are not provided. Customer-specific evidence is limited to stated OEM service for popular brands.
Supplier typeThe supplier explicitly identifies itself as a professional technology supplier and automatic-door manufacturer. Its stated products and capabilities include automatic doors, professional technical R&D, and manufacturing through two production lines/bases.
CertificationsThe company description states that the supplier has attained ISO9001, ISO14001, SGS, and CE certifications. The slices do not provide certificate numbers, validity dates, scopes, or supporting documents, but they do contain an explicit certification claim.
After-Sales capabilityThe supplier has a customer-complaint procedure, but no written complaint records, and it has no written corrective/preventive-action procedures or records. It also reports no overseas agents or branches, overseas warehouse, overseas showroom, or overseas service countries, indicating limited documented after-sales infrastructure outside its home market.
R&D capabilityThe supplier provides 3D software design, ODM, OEM, and SDK capabilities, demonstrating technical development and integration resources. Nevertheless, it explicitly reports no new products during the past year, which is direct evidence of limited recent product innovation.
Production capacityThe supplier reports two production lines, an assembling line, 41–50 quality-control staff, valid contracts with associated subcontractors, and automatic-door output of 7,722 sets. Finished-product inspections are performed under uniform written instructions, although the company description gives different production-capacity figures, creating an unresolved capacity discrepancy.
