AI-Powered supplier vetting

SummaryThe supplier is a hydraulic machinery and components manufacturer with mechanical equipment R&D, industrial design, technical services, and import/export activities. It reports over 30 years of experience, four production lines, 50 quality-control staff, hydraulic-cylinder output of 8,000 pieces, and lead times within 15 working days in both peak and off-peak periods. Its capabilities are supported by ISO9001:2015, ISO14001, ISO45001:2018, and CE certifications. Evidence also indicates sample-based customization, recent new-product development, and ODM availability. However, the supplier has no available SDK, does not provide OEM services for well-known brands, lacks continuous quantity reconciliation for production batches, and has no documented outsourcing SOP. Financial records are identified by year, but no substantive financial performance information is provided.

Supplier typeThe supplier is identified as Feiyang Science and Technology Co and operates in mechanical equipment R&D, industrial design, technical services, hydraulic power machinery and component manufacturing and sales, and import/export. This supports classification as a hydraulic machinery manufacturer with engineering and technical-service capabilities.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 management-system certifications, together with CE product compliance certification. These are explicit certifications relevant to quality, environmental, occupational-health, and product-compliance management.

After-Sales capabilityThe supplier reports clear procedures and followed records for corrective and preventive actions related to service capability and for handling customer complaints. This provides direct evidence of documented after-sales and complaint-management processes.

R&D capabilityThe supplier reports R&D-related product information, at least one new product during the past year, ODM services, and business activities covering mechanical R&D, industrial design, technical development, and AI application software development. However, it also reports no available SDK, so innovation capability is evidenced but not complete across all technical areas.

Production capacityThe supplier reports four production lines, 50 quality-control staff, hydraulic-cylinder output of 8,000 pieces, and lead times within 15 working days in both peak and off-peak seasons. Nevertheless, it does not continuously reconcile production quantities by batch and has no outsourcing SOP, indicating process-control gaps despite substantial stated production resources.

Customization capabilityBoth R&D/design-related records state customization from samples, and the supplier also reports ODM service availability. This directly supports sample-based customization and original-design manufacturing capability.
