AI-Powered supplier vetting
SummaryThe supplier manufactures and sells industrial automatic control devices, electric vehicle charging equipment, and related products, with Frequency Inverter identified as the offered product. It holds ISO9001:2015 and ISO14001:2015 certificates. Evidence indicates broad customization and ODM capability, recent new-product development, 25 years of R&D engineer experience, more than 10 production lines, and established finished-product inspection instructions. The supplier exports to multiple regions and reports peak- and off-season lead times within 15 workdays. Service infrastructure is limited: it has no overseas warehouse, showroom, agent, or branch, and reports no overseas service-country coverage. Customer complaint handling has a procedure but no written records. OEM service for known brands and participation in Elektro 2023 are documented, but specific customer names or case details are not provided.
Supplier typeThe supplier is a manufacturer and seller of industrial automatic control system devices, auto parts, electric vehicle charging piles, and chargers, with Frequency Inverter listed among its products. It also provides OEM services for known brands, supporting classification as a manufacturer with OEM capability.
CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates. These are explicit certifications relevant to quality and environmental management systems.
After-Sales capabilityThe supplier has a customer-complaint procedure, but no written complaint-handling records; it also lacks overseas warehouses, showrooms, agents, and branches, and reports zero countries with overseas services. Participation in Elektro 2023 and stated lead times within 15 workdays provide some service-related evidence, but the documented overseas and complaint-management capability is limited.
R&D capabilityThe supplier reports new products during the past year, ODM services, 25 years of total R&D engineer experience, and a stated focus on technology improvement and innovation. It does not have an available SDK, but this limitation does not negate the broader documented R&D and product-development capabilities.
Production capacityProduction evidence includes Chip Mounting, CNC, and Assembly lines, more than 10 operating production lines, 31–40 quality-control staff, and uniformly followed finished-product inspection instructions. The supplier also reports variable frequency drive output, although the provided output entry is not sufficiently reliable for quantitative assessment.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and separately reports ODM service availability. These statements directly support broad customization capability.
