AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier providing 3D software design and multiple customization options. It holds ISO9001:2015, CE, and RoHS certifications, has three R&D engineers, four quality-control test devices, and maintains R&D design, review, verification, and validation documentation. Its technical development is supported by cooperation with Shandong University and Northwestern Polytechnical University. Production-related evidence includes valid contracts with affiliated subcontractors and in-stock capability, but no overseas warehouse, showroom, agents, or branches. After-sales support is reflected in engineers’ technical-support responsibilities and a documented customer-complaint process. Financial records are indicated for three years, although no performance figures are provided. The supplier reports no SDK, no Fortune 500 cooperation, and no overseas service coverage; therefore, these areas should not be treated as strengths.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and describes its focus on industrial-control DC electronic equipment circuit breakers. It also reports branches in Suzhou and Shenzhen with a sales and service network, supporting its classification as a technical equipment provider.

CertificationsThe supplier holds an ISO9001:2015 management-system certificate and reports CE and RoHS product certifications. These are explicit certifications relevant to quality management and product compliance.

After-Sales capabilityThree technology engineers are responsible for confirming customer requirements and providing technical after-sales support. The supplier has a clear customer-complaint procedure with follow-up records, although it lacks written corrective and preventive-action procedures or records.

R&D capabilityThe supplier provides 3D software design services, has three R&D engineers, maintains R&D audit documentation, and collaborates with doctoral supervisors and two universities on advanced-product development. However, it explicitly reports that no SDK is available, so innovation capability is supported in some areas but not universally demonstrated.

Production capacityThe supplier reports four quality-control test devices, valid manufacturing-capacity contracts with affiliated subcontractors, in-stock capability, and quality assurance in quality-control processes. It does not have overseas warehouses or showrooms, which limits overseas fulfillment infrastructure but does not establish a deficiency in core production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization, together with 3D software design services. This directly demonstrates broad customization coverage.
