Supplier typeThe supplier is a limited company founded in 2009, identified as a national high-tech enterprise under China Baoan Group, with business activities centered on hydraulic component R&D, manufacturing, and sales. Its stated product scope is valves, serving industrial equipment and machinery markets.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certifications, with ISO45001:2018 also listed in its management and sustainable-development certification information. CCC is listed as product compliance certification, providing explicit evidence of both management-system and product certification.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer-complaint handling. It accepts multiple quotation and payment terms and reports a one-month average lead time in both peak and off-season, although the slices do not explicitly describe warranty or field-service coverage.

R&D capabilityThe supplier is described as a national high-tech enterprise with dedicated hydraulic-component R&D activities and 11 R&D engineers. However, it explicitly reports no available SDK, so the evidence supports product-development capability but not SDK-based integration capability.

Production capacityThe supplier reports a 19,618.0 m² manufacturing plant and 30 production lines, indicating established manufacturing infrastructure for hydraulic valves. However, it does not conduct ongoing quantity reconciliation for every batch or production volume, which is a stated production-control weakness.

Customization capabilityThe supplier supports customization from samples, designs, full customization, minor customization, and flexible customization. It also reports OEM capability for well-known brands, providing explicit evidence of broad customization and OEM support.

Client casesThe supplier reports providing OEM services for well-known brands and a repeat-buyer preference rate of 80%~100%. However, it explicitly reports no collaboration with Fortune 500 companies, and no named customer cases are provided, so the evidence supports customer retention and OEM experience but not high-profile reference cases.
