AI-Powered supplier vetting
SummaryQingdao Zehan Machinery Manufacturing Co., Ltd. is a Chinese manufacturer/factory in Shandong with eight production lines and documented production of stamped, machined, and hot-forged parts. It reports ISO 9001 certification, quality-control procedures, material traceability, complaint-handling records, and corrective-action procedures. The supplier offers extensive customization, ODM services, and OEM services for popular brands, and has exported for 19 years, with exports representing 90% of total sales. Its overseas support footprint is limited: it reports no overseas warehouse, showroom, agents, or branches. Financial information is incomplete for assessment, and the available R&D staffing indicator is limited, although new products were developed during the past year.
Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company located in Qingdao, Shandong, China. This supports direct manufacturing status rather than a trading-only classification.
CertificationsThe supplier reports certification of its management system to ISO 9001. This is explicit evidence of holding a recognized quality-management certification.
After-Sales capabilityThe supplier has a documented complaint-handling procedure with followed records, maintains quality-control records, and reports material traceability. However, the slices do not specifically describe warranty terms, spare-parts support, repair networks, or response times, so the assessment is based on complaint and quality-process evidence only.
R&D capabilityThe supplier reports that it introduced new products during the past year and provides ODM services. It also reports fewer than five years of total R&D-engineer experience and no available SDK, so the evidence supports some product-development capability but not a strong or broad innovation infrastructure.
Production capacityThe supplier operates eight production lines and reports production of stamped, machined, and hot-forged parts, supported by standardized finished-product inspection instructions. Its quality system also includes traceability and maintained records, indicating established production and control processes.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, in addition to ODM services. This is direct evidence of broad customization coverage.
Client casesThe supplier states that it provides OEM services for popular brands, has exported for 19 years, and participated in the 2024 Mexico Industrial Exhibition. These are relevant customer and market-experience indicators, but no named customers, project details, or verifiable case studies are provided.
