AI-Powered supplier vetting

SummaryKeKe Group Ltd. is a China-based valve manufacturer established in 2002, offering research and development, manufacturing, sales, and service across industrial valves and pipe fittings. It reports TS certification for pressure-piping components and safety accessories, ISO9001 certification, and ISO14001 certification. The supplier has CNC and related machining equipment, a pressure-test machine, one quality inspector, in-stock capability, and valid manufacturing contracts with associated subcontractors. It supports extensive customization and OEM services for popular brands. However, the available evidence identifies no written procedures or records for corrective and preventive actions, complaint handling, or supplier-service assessment, and states that quality assurance is absent. It has no overseas agents, branches, warehouses, or showrooms, and reports no countries with overseas services. Financial information is limited to years listed for recent reporting periods without performance figures. No...

Supplier typeThe supplier is described as a professional valve high-tech enterprise combining research and development, manufacturing, sales, and service. Its products include valves and pipe fittings such as ball, butterfly, check, gate, safety, and globe valves, placing it in the industrial equipment and components sector.

CertificationsThe company states that it holds a special equipment production license and TS certification for pressure-piping components and safety accessories, as well as ISO9001 quality-system and ISO14001 environmental-management certifications. These explicitly support certification coverage relevant to its pressure-equipment and manufacturing activities.

After-Sales capabilityThe supplier reports in-stock capability and participation in an offline trade show, but it has no overseas agents or branches, overseas warehouse, or overseas showroom, and reports overseas services in zero countries. Complaint handling and corrective/preventive action have no written procedures or records, while service-capability assessment also lacks documented procedures and records.

R&D capabilityThe supplier reports research and development activity, OEM capability, and recognition as a national high-tech enterprise and several provincial or municipal technology and innovation enterprises. However, it has no available SDK, which is relevant to software-development integration but not necessarily to valve-product innovation.

Production capacityProduction evidence includes CNC equipment, CNC lathes, lathes, radial drilling equipment, and pressure-test machinery; one quality inspector; valid manufacturing contracts with associated subcontractors; in-stock capability; and reported lead times of within 15 workdays to one month in both peak and off-season. Nevertheless, finished products are checked by packing staff, and the supplier states that quality assurance is absent, creating a documented quality-control weakness.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports OEM capability for popular brands, providing direct evidence of broad product-adaptation and manufacturing support.
