AI-Powered supplier vetting

SummaryThe supplier is identified as a factory with two production lines, stated annual output across prosthetic feet, prosthetic legs, orthotics, and knee joints, and three quality inspectors. It reports broad customization, recent new-product development, ODM capability, OEM service for well-known brands, ISO13485:2016 and CE certification, and more than ten patents. Quality procedures include documented corrective actions, complaint handling, and quality assurance, but raw-material traceability is explicitly absent. The supplier has inventory capacity and stated lead times within 15 working days, but lacks overseas warehouses, showrooms, agents or branches, and offline trade-show participation. No valid manufacturing-capacity contract with related subcontractors is reported. Financial credibility cannot be fully assessed from the provided records.

Supplier typeThe supplier is explicitly identified as a factory, indicating direct manufacturing status rather than only a trading or service intermediary.

CertificationsThe company states that it holds ISO13485:2016 quality management system certification and CE certification, supported by a description emphasizing quality-system compliance. The evidence is supplier-reported, and no certificate validity details are provided.

After-Sales capabilityThe supplier has documented procedures and records for customer complaints and corrective/preventive actions, and reports inventory capacity and lead times within 15 working days. However, it has no overseas warehouse, showroom, agent or branch, so localized overseas support is limited.

R&D capabilityThe supplier reports new products within the past year, ODM services, more than ten patent certificates, and a technology-focused production approach. It does not have an available SDK, but that limitation does not negate the broader evidence of product-development capability.

Production capacityThe supplier operates two production lines, reports output of 30,000 prosthetic feet, 5,000 prosthetic legs, 10,000 orthotics and 5,000 knee joints annually, and has CNC lathing, machining-center and drilling equipment. It also reports three quality inspectors and lead times within 15 working days, but has no valid capacity contract with related subcontractors.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, full customization, flexible customization and minor customization. This is explicit evidence of a broad customization offering.

Client casesThe supplier states that it provides OEM services for well-known brands and exports to markets including South America, Eastern Europe, the Middle East, North America, Southeast Asia, Eastern Asia, Oceania, Western Europe and Africa. No named customers, projects or independently verifiable case details are provided.
