AI-Powered supplier vetting

SummaryQiangxin is identified as a professional technical supplier focused on battery manufacturing, battery parts, energy-storage products, charging infrastructure, and used power-battery recycling. It provides 3D software design and broad customization services, supported by five R&D engineers, and has documented quality-control, complaint-handling, corrective-action, traceability, and warehouse procedures. The supplier reports inventory capability, valid manufacturing-capacity contracts, four quality-control staff, and two quality-control testing devices. It has export capability and some export experience, but no overseas warehouse or showroom. Financial information is limited to year labels without substantive performance data. No certification holdings or customer case references are provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier and operates across battery manufacturing, battery-part production and sales, energy-storage applications, charging infrastructure, and used power-battery secondary utilization. This indicates a specialized battery and energy-storage supplier rather than a general trading company.

After-Sales capabilityThe company states that it provides comprehensive pre-sales consultation and after-sales service. It also has documented procedures and records for handling customer complaints and corrective and preventive actions, supporting an established service-response process.

R&D capabilityThe supplier is identified as having R&D capability, employs five R&D engineers, and assigns them to customize new products according to customer demands. However, it reports no available SDK, so the evidence supports product-development capability but not SDK-based integration capability.

Production capacityThe business scope includes battery and battery-part manufacturing, metal and electronic-component activities, and charging infrastructure. The supplier reports valid manufacturing-capacity contracts, inventory capability, four quality-control staff, two testing devices, documented inspection procedures, and a one-month average lead time in both peak and off-season periods.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D software design services. Five R&D engineers are responsible for developing products according to customer requirements, providing direct evidence of broad customization support.
