AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier engaged in wind-power technology services, photovoltaic equipment rental, battery and electronic equipment activities, and related sales or construction services. It holds ISO9001:2015, ISO45001:2018, ISO14001, and CE certifications. Service controls include written procedures, records, supplier-list management, corrective and preventive actions, complaint handling, quality assurance, and material traceability. The supplier provides 3D design, flexible customization, ODM, and OEM services, but reports no available SDK, no private-mold capability, and no new products in the past year. Stated delivery times are within 15 workdays off-season and one month during peak season. Financial information is limited to year references, so credibility cannot be determined. Evidence of customer cases is limited to OEM service for well-known brands and participation in the Thailand Exhibition.

Supplier typeThe supplier explicitly describes itself as a professional technical supplier. Its stated business activities cover wind-power technology services, wind-turbine and component sales, battery and electronic equipment manufacturing or sales, photovoltaic equipment rental, and certain construction and design services.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, plus CE product compliance certification. These certifications provide explicit evidence of relevant management and product-compliance credentials.

After-Sales capabilityService capability is supported by written procedures and followed records, a corrective and preventive action mechanism, complaint-handling procedures, quality assurance, and material traceability. The supplier also lists training as an overseas service offering, although overseas service coverage is recorded as zero countries.

R&D capabilityThe supplier reports no available SDK and no new products during the past year. Although ODM service is available, these explicit limitations indicate insufficient evidence of strong recent product innovation or software-development capability.

Production capacityThe supplier reports manufacturing capability for batteries, electronic components, and electromechanical equipment, along with quality assurance, traceability, and a stated quantity of one for its own-brand quality-control capability. Delivery times are within 15 workdays off-season and one month during peak season, supporting some operational capability, but production capacity is not fully quantified.

Customization capabilityThe supplier provides 3D software design services, flexible customization, ODM services, and OEM services for popular brands. However, it explicitly reports no private-mold capability, so customization is demonstrated primarily through design and manufacturing services rather than proprietary tooling.

Client casesThe supplier reports providing OEM services for well-known brands and identifies Thailand Exhibition as a trade-show activity. These are direct indicators of market-facing experience, but no customer names, project details, order volumes, or performance outcomes are provided.
