SummaryHebei Yingxing Gear Co., Ltd. was established in 1996 and is described as integrating research and development, production, and sales, although another record classifies the company as a trading company. It reports a 30,000-square-meter workshop, 120 employees, and 30 professional and technical personnel. The supplier holds ISO 9001 and ISO 20000 certifications, has documented corrective-action and complaint-handling procedures, and reports quality assurance and raw-material traceability. It supports extensive customization and has documented finished-product inspection instructions. Production-related evidence includes advanced heat-treatment and gear-processing equipment and applications in multiple machinery sectors. However, it reports no available SDK, no in-stock capacity, no overseas warehouse, no overseas agents or branches, and no valid manufacturing-capacity contract with related subcontractors. Financial records are identified for 2021–2023, but no performance values are provided. Environmental...

CertificationsThe supplier reports holding ISO 9001 and ISO 20000 management-system certifications. This is explicit evidence of certification holdings, although the records do not state their validity periods or scope.

After-Sales capabilityThe supplier has clear, followed procedures for corrective and preventive actions and customer complaints, supporting structured service handling. However, it reports no in-stock service capacity, overseas warehouse, overseas showroom, overseas agents or branches, and no overseas service countries, which limits documented international service coverage.

R&D capabilityThe supplier has an R&D function, 6–10 years of total R&D-engineer experience, 30 professional and technical personnel, and reports introducing advanced equipment and new gear materials. However, it explicitly has no available SDK, so the evidence supports product and process development but not SDK-related capability.

Production capacityThe supplier reports a modern 30,000-square-meter workshop, 120 employees, specialized gear-processing and heat-treatment equipment, and applications across multiple machinery sectors. Nevertheless, it reports no valid manufacturing-capacity contract with related subcontractors and no in-stock capacity; overall production capability is supported, but capacity assurance is incomplete.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also has documented and uniformly followed finished-product inspection instructions, providing direct evidence of customization and associated inspection control.
