AI-Powered supplier vetting

SummaryShenzhen Wangda Hengtai Technology Co., Ltd. is identified as a China-based trading company engaged in cooling fans and related products. Its stated capabilities include integrated research and development, production, and sales, advanced production equipment, an R&D team, complete molds, hundreds of product specifications, five production lines, and 6–10 quality-control staff. Reported product certifications include CE and RoHS for all cooling-fan series. The supplier provides output figures for fan guards, blower fans, EC fans, DC fans, and AC fans, but its manufacturing-plant area and staff experience are both reported as zero, creating uncertainty about operational depth. Evidence is insufficient to assess after-sales service, financial credibility, customization execution, or customer cases.

Supplier typeThe supplier is explicitly classified as a trading company, while its own description presents it as a manufacturing-and-trade integrated enterprise focused on cooling fans. Its registered entity is a limited company based in Shenzhen, China.

CertificationsThe supplier states that all types of cooling-fan series have passed globally recognized CE and RoHS certifications. This is explicit evidence of certification coverage for its product series.

R&D capabilityThe company explicitly identifies technology and innovation as core drivers, reports an R&D team and advanced production equipment, and describes plans focused on heat-dissipation technology, new energy, and intelligent manufacturing. These statements support an established innovation orientation, although no specific patents or completed innovations are provided.

Production capacityThe supplier reports integrated production capability, five production lines, complete molds, hundreds of product specifications, and stated annual outputs for fan guards, blower fans, EC fans, DC fans, and AC fans. However, the manufacturing-plant area and total staff experience are both reported as zero, so the scale and reliability of the stated production infrastructure cannot be fully validated.
