AI-Powered supplier vetting

SummaryZhengzhou CY Scientific Instrument Co., Ltd. is a China-based limited company established in 2013 and identified as a factory. It develops and manufactures scientific and advanced-materials equipment, including CVD systems, tube furnaces, muffle furnaces, dental furnaces, and plasma cleaners. The supplier reports more than 10 production lines, a 565.6 m² manufacturing plant, 6–10 quality-control staff, and order fulfillment within 15 workdays in both peak and off-peak periods. Its export sales share is reported at 71%–90%, with markets spanning multiple regions. The company describes research and development activity and technical accumulation, but only three R&D engineers are reported. No supplier management-system certification is listed. Trade evidence shows one transaction associated with each of three records involving the same Kazakhstan buyer, which provides limited customer-case evidence. After-sales and customization capabilities are not explicitly documented.

Supplier typeThe supplier is identified as a factory and a limited company based in Zhengzhou, China, with manufacturing activity, a stated production site, and products including furnaces, CVD systems, and plasma cleaners. Its description presents an integrated R&D, manufacturing, and management operation focused on scientific and advanced-materials equipment.

CertificationsThe supplier’s certification of management systems is explicitly recorded as “NIL.” This indicates no management-system certification is evidenced in the provided information.

R&D capabilityThe company explicitly describes itself as a scientific and technological innovation enterprise engaged in research, development, new-product development, and technical accumulation in thermal engineering and advanced-materials preparation equipment. The reported total R&D-engineer experience is 3, which supports the existence of R&D activity but does not demonstrate extensive R&D depth.

Production capacityThe supplier reports more than 10 production lines, a 565.6 m² manufacturing plant, 6–10 quality-control staff, 18 total employees, and order fulfillment within 15 workdays in both peak and off-peak seasons. These figures provide explicit evidence of operating production capacity and relatively consistent stated lead times.
