AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier with 3D software design capability and broad customization services. It holds ISO9001:2015 and ISO14001:2015 certifications, reports 30 years of R&D engineer experience, and maintains documented quality, corrective-action, complaint-handling, and supplier-assessment procedures. Quality controls include 100% finished-product inspection, 21–40 quality personnel, and raw-material traceability. Production information indicates five production lines, stated lead times within 15 workdays in both peak and off-peak periods in one slice, while another reports one-month average lead times, so delivery performance requires clarification. Financial information is only represented by reporting years, without substantive financial results. No SDK is available, overseas service coverage is listed as zero countries, and no customer cases are explicitly provided.
Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes its business in relation to intelligent power-grid construction. It also reports 30 total years of R&D engineer experience, supporting a technically oriented supplier profile.
CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates. These are explicit certification records relevant to quality and environmental management.
After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions, customer complaints, and service-capability assessment. However, the overseas-service coverage is listed as zero countries, so the evidence supports procedural capability but not broad international after-sales coverage.
R&D capabilityThe supplier reports professional R&D capability, 3D software design services, extensive customization options, and 30 total years of R&D engineer experience. However, it explicitly states that no SDK is available; the evidence supports design and engineering capability but does not establish full software-development integration capability.
Production capacityProduction-related evidence includes five production lines, 100% finished-product inspection, 21–40 quality-control staff in separate records, raw-material traceability, and stated export experience of 29 years. Delivery data is inconsistent, with one slice stating within 15 workdays during both seasons and another stating one-month average lead times, so capacity and delivery consistency require confirmation.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These repeated entries demonstrate a broad stated customization scope.
