AI-Powered supplier vetting

SummaryShandong Jianyu Heavy Industry Co., Ltd. is identified as a combined company manufacturing and selling fans, blowers, and related mechanical and environmental-protection equipment. It reports broad customization, ODM services, new products within the past year, and OEM service for known brands. Its export experience is stated as eight years, with exports representing 51%–70% of total sales. The company describes technical R&D, design, production, and after-sales capabilities, but several service-control processes lack complete documented records. No certifications, specific customer cases, or overseas service infrastructure are evidenced. Financial information is limited to references to fiscal years and balance sheets, without substantive financial performance data.

Supplier typeThe supplier is named Shandong Jianyu Heavy Industry Co., Ltd. and classified as a combined company. Its stated business covers manufacturing and sales of fans and blowers, general equipment, environmental-protection special equipment, and mechanical equipment, indicating a manufacturer-supplier rather than a purely trading entity.

After-Sales capabilityThe company states that it has technical, design, production, and after-sales capabilities and a developed after-sales service system. However, its complaint-handling and corrective/preventive-action mechanisms reportedly have procedures but no written records, while supplier-service assessment has records without a written procedure; this supports stated capability but indicates incomplete documented control.

R&D capabilityThe supplier reports technical R&D and design capabilities, new products within the past year, ODM services, and multiple design customization options. It also reports no available SDK, but the provided evidence still explicitly supports product-development and design activity.

Production capacityThe supplier describes production capability and its business scope explicitly includes manufacturing fans, blowers, general equipment, and environmental-protection special equipment. The slices do not provide capacity, equipment, factory scale, or production volume data, but they do support an established manufacturing function.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization capability.

Client casesThe supplier states that it provides OEM services for known brands, which is evidence of brand-related OEM experience. However, no customer names, project descriptions, order references, or independently verifiable case details are supplied, so the depth and verifiability of customer cases remain limited.
