AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier offering 3D software design and broad customization services. It operates CNC lathing, cutting, and punching facilities, reports four production lines, and has stated output for heating element flanges. It exports to multiple regions, with 51%–70% of sales from exports, and normally indicates lead times of within 15 workdays off-season and one month during peak periods. Quality assurance, raw-material traceability, ISO 9001:2015 certification, and manufacturing contracts with associated subcontractors are documented. However, the supplier has no available SDK, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no offline trade-show participation. Corrective-action, complaint-handling, finished-product inspection, and supplier-assessment procedures lack written records. Financial-period labels are provided, but no substantive financial performance data is available.
Supplier typeThe supplier is explicitly classified as a professional technical supplier. Its facilities include CNC lathing, cutting, and punching, and it serves export markets across South America, Eastern Europe, North America, and Western Europe.
CertificationsThe supplier reports quality assurance, raw-material traceability, and an ISO 9001:2015 certificate. It also conducts regular fire drills, although no factory environmental impact assessment report is available.
Production capacityProduction evidence includes CNC lathing, cutting, and punching facilities, four production lines, stated heating element flange output, 25 qualified service suppliers, and valid manufacturing contracts with associated subcontractors. Capacity management is weakened by the absence of continuous quantity reconciliation for each batch or mass production.
Customization capabilityThe supplier explicitly supports customization from designs, samples, full customization, minor customization, and flexible customization, as well as 3D software design services. This is direct evidence of broad customization capability.
