AI-Powered supplier vetting

SummaryAotian Machinery Manufacturing Co., Ltd. is identified as a China-based paper machinery supplier headquartered in Qinyang, Henan. The available information describes it as a manufacturer of paper machines, pulping equipment, spare parts, and related environmental-protection and tissue-converting solutions, although one slice also labels the company type as a trade company. It reports 8 production lines, annual paper-machine output of 20 sets, 31–40 quality-control staff, 11–20 years of R&D-engineer experience, a nearly 30,000 m² facility, and 32 patents. ISO 9001 and ISO 22000 are listed. Export activity spans multiple regions, with exports representing 51%–70% of sales. Evidence is insufficient to verify after-sales service depth, financial credibility, customization execution, or substantial customer references.

Supplier typeThe supplier is described as a manufacturer/factory and as a specialized producer of paper machines, pulping equipment, paper-machine parts, roll-processing equipment, and related solutions. However, another record classifies the company nature as a trade company, creating a minor inconsistency in entity characterization.

CertificationsThe supplier lists ISO 9001 and ISO 22000 management-system certifications and states that it has product certificates. The slices do not provide certificate numbers, issuing bodies, validity dates, or the specific products covered, so the listed certifications are positive evidence but cannot be independently verified from the data.

R&D capabilityThe supplier reports a professional R&D team, 11–20 years of total R&D-engineer experience, and 32 patents. Its product scope includes environmental-protection machinery, pulp and paper-making systems, and tissue-converting machinery, providing explicit evidence of engineering and product-development activity.

Production capacityThe supplier is described as a manufacturer with a nearly 30,000 m² facility, 8 production lines, 31–40 quality-control staff, and reported paper-machine output of 20 sets annually. Its stated specialization in complete paper-machine production lines, pulping equipment, and roll processing supports a substantial manufacturing capability.
