The available information does not provide verified customer cases or sufficient evidence to assess financial credibility.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company based in Zhengzhou, China. Its stated business covers multiple machinery categories, although one record also classifies the company nature as a trading company, indicating a mixed or inconsistent classification.

CertificationsISO 9001 certification is reported, and a TUV Rheinland audit record is listed with a report period from September 5, 2024 to September 4, 2025. The audit result is recorded as '0' without an explanatory interpretation, so the certification evidence supports a positive assessment but the audit outcome cannot be independently characterized.

After-Sales capabilityThe supplier explicitly claims guaranteed after-sales service, a two-year warranty, 100% pre-shipment QC inspection, and one-station support in which sales managers, engineers, QC, and PMC follow customers until the machines are operating properly. These are stated service commitments, although no external service-performance records are provided.
