SummaryYingkou Ruifeng Powder Equipment Co., Ltd. is a China-based limited company established in 2014, with 85 employees and a 16,208 m² manufacturing plant. The supplied information identifies it as a powder engineering technology and equipment manufacturer, although another record classifies the company nature as a trading company. Its capabilities cover powder mills, vertical roller mills, classifiers, conveyors, dosing and packing machines, and industrial automation. The company reports ISO9001:2015 certification, five years of R&D engineer experience, domestic and overseas sales, and a typical off-peak lead time of 4–6 months. Evidence supports manufacturing, R&D, and export experience, but is insufficient to confirm after-sales service performance, financial credibility, customization execution, or specific customer cases.

Supplier typeThe supplier is identified as Yingkou Ruifeng Powder Equipment Co., Ltd., a China-based limited company established in 2014. Its description presents it as a high-tech powder engineering R&D, manufacturing, and sales enterprise with a 16,208 m² plant, while another record labels the company nature as a trading company; therefore, its principal supplier role is supported as manufacturing-oriented but not completely consistent across records.

CertificationsThe supplier explicitly reports holding an ISO9001:2015 certificate. This provides direct evidence of a certified quality management system, although no additional certifications or certificate scope details are provided.

R&D capabilityThe supplier describes itself as a high-tech enterprise engaged in powder engineering R&D and equipment manufacturing, with research into ultrafine vertical roller mills, classifiers, dosing and packing systems, and an experienced R&D team. Five years of total R&D engineer experience is reported, supporting an active innovation function.
