AI-Powered supplier vetting

SummaryShandong Dofun Refrigeration Technology Co., Ltd. is identified as a Chinese manufacturer of refrigeration valves and related industrial equipment, established in 2012 with 85 employees and a 13,000 m² manufacturing area. The supplier reports six production lines, annual refrigeration-valve output of 200,000 sets, quality-control staffing of 11–20 employees, and delivery within 15 working days in both peak and off-peak seasons. It serves domestic and multiple overseas markets and accepts several trade and payment terms. The materials indicate product-development activity and technical capabilities, but provide no verified management-system certifications, after-sales service details, customization evidence, or named customer cases. Company information contains inconsistencies, including different registered-capital and facility descriptions, which should be verified before qualification.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and operates in industrial equipment and components, with refrigeration valves and related valve products as its stated focus. Its legal and company names vary slightly across the records, but the business type and product orientation are consistent.

CertificationsThe supplier-management-system certification field is explicitly recorded as "NIL." No certification such as ISO is provided in the available information, so certification compliance cannot be established.

R&D capabilityThe supplier states that it pursues continuous product innovation, has six R&D engineers, and operates multiple advanced valve production lines and experimental testing facilities. These statements support some innovation resources, although no patents, formal R&D projects, or measurable innovation outcomes are provided.

Production capacityThe supplier reports a 13,000 m² plant, six production lines, 85 employees, quality-control staffing of 11–20 people, and annual refrigeration-valve output of 200,000 sets. It also states that orders can be fulfilled within 15 working days during both peak and off-peak periods, providing explicit evidence of established production capacity.
