SummaryThe supplier is identified as a professional technical supplier with electronic, mechanical and electrical, switching-control, photovoltaic, instrumentation, and related technical-service activities. It demonstrates broad customization and 3D software design capabilities, plus SDK availability. Production-related evidence includes winding and assembly facilities, 12 quality inspectors, inventory capacity, valid manufacturing contracts with associated subcontractors, documented inspection procedures, and a stated peak-season lead time of one month. Quality and compliance evidence includes ISO9001:2015, ISO14001, RoHS, CE, and an FCC raw-material test report. The supplier has documented corrective-action, complaint-handling, quality-assurance, and traceability procedures. However, it reports no overseas warehouse, showroom, agents or branches, or overseas service countries, and no customer cases are provided. Financial records are referenced for 2022–2024, but no substantive financial figures or performance...
Supplier typeThe supplier explicitly identifies itself as a professional technical supplier. Its stated scope covers switch-control equipment, electronic components, mechanical and electrical equipment, photovoltaic equipment and components, instrumentation, and related technical services, indicating a manufacturing and technical-services profile.
CertificationsThe supplier reports ISO9001:2015 and ISO14001 management-system certifications, as well as RoHS and CE product certifications. An FCC raw-material test report is also listed, providing explicit evidence of multiple quality, environmental, and product-compliance credentials.
After-Sales capabilityThe supplier has documented procedures and records for corrective and preventive actions and customer-complaint handling, together with stated quality assurance and traceability. However, it has no overseas warehouse, showroom, agents or branches, and reports service coverage in zero countries, so international after-sales infrastructure is limited.
R&D capabilityThe supplier reports professional R&D capability, 3D software design services, and an available SDK. These are direct indicators of technical development and software-related capability, although no information is provided on patents, proprietary products, or innovation outcomes.
Production capacityProduction evidence includes winding and assembly facilities, 12 quality inspectors, valid manufacturing contracts with each associated subcontractor, inventory capacity, documented finished-product inspection procedures, and written supplier-service assessment procedures with records. Reported lead times are within 15 working days off-season and one month during peak season, supporting an established production and fulfillment capability.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design services, directly supporting design-driven and tailored product development.
