AI-Powered supplier vetting

SummaryThe supplier is a professional technical manufacturer focused on mud pumps, plunger pumps, pumping equipment, oilfield and wellhead accessories, valves, drilling and production accessories, rubber and polyurethane components, forgings, castings, and engineering materials. It provides 3D design, ODM, OEM, and multiple customization services. Production is supported by three lines, reported annual output of 20,000 bi-metal liners, and lead times within 15 working days in both peak and off-peak seasons. Quality-related procedures cover corrective actions, complaint handling, quality assurance, and raw-material traceability. The supplier holds an ISO9001:2015 certificate and has environmental assessment and fire-drill records. However, it has no available SDK, no new products reported in the past year, no overseas warehouse, showroom, agent, or branch, no offline trade-show participation, and no valid manufacturing-capacity contract with related subcontractors. Financial information is represented only by...

Supplier typeThe supplier explicitly identifies as a professional technical supplier and operates in research and development, production, and sales across mud pumps, pumping equipment, oilfield accessories, valves, drilling and production components, and related engineered materials. This establishes a specialized industrial supplier profile.

CertificationsThe supplier reports holding an ISO9001:2015 certificate and also has a factory environmental impact assessment report. These are explicit documented management and environmental credentials, although no broader certification portfolio is provided.

Production capacityThe supplier operates three production lines, reports 20,000 bi-metal liners of annual output, maintains in-stock capacity, and states lead times within 15 working days in both peak and off-peak seasons. A deficiency is that no valid manufacturing-capacity contract exists with related subcontractors, creating a documented capacity-governance weakness.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, flexible customization, 3D design services, ODM, and OEM for well-known brands. These offerings directly support a broad range of customized product requirements.
