AI-Powered supplier vetting

SummaryQingdao Yonglihao Machinery Co., Ltd. is identified as a Chinese trading company operating from Qingdao, Shandong, with factory-related information describing ODM/OEM metal stamping, welding, machining, and die casting capabilities. The supplier states more than 10 years of experience, export activity to Africa, Europe, and North America, and 90% of sales from exports. Its stated equipment includes automatic welding machines, stamping machines, die-casting machines, machining centers, and CNC machines. Customization is supported by its stated ODM/OEM design and manufacturing services and broad material range. However, certification details are unspecified beyond “Others,” customer cases are not provided, and the supplied company-establishment dates are inconsistent. After-sales service is claimed, but operational evidence is limited.

Supplier typeThe supplier is explicitly classified as a Trading Company, while its background and company descriptions also state that it operates or represents factory capabilities for ODM/OEM metal stamping, welding, machining, and die casting. The information therefore indicates a trading-company classification with described manufacturing operations, but does not resolve the distinction between legal entity and factory ownership.

After-Sales capabilityThe supplier explicitly promotes excellent after-sales service and states that its ODM/OEM business includes sales and service. However, no specific service process, service team structure, response commitment, warranty terms, or performance evidence is provided.

R&D capabilityThe supplier describes ODM/OEM design and manufacturing services and reports two years of total R&D-engineer experience. This supports some product-development capability, but the slices provide no information on patents, dedicated R&D facilities, new-product development results, or innovation certifications.

Production capacityReported equipment includes 10 automatic welding machines, 100–500-ton stamping machines, 180–500-ton die-casting machines, 20 machining centers, and CNC machines. The supplier also reports more than 10 production lines, an 80.0 m² manufacturing-plant area, a one-month peak and off-peak lead time, and capability across several metal processes; the small stated plant area should be considered alongside the claimed equipment and line counts.

Customization capabilityThe supplier explicitly offers ODM/OEM design and manufacturing for stamping, welding, machining, and die casting, and states that it can handle varied metal production using carbon steel, stainless steel, aluminum, zinc, brass, copper, and iron. These statements directly support broad material and process customization capability.
