AI-Powered supplier vetting

SummaryPinghu Tianlong Machinery Manufacturing Co., Ltd. is a hydraulic-cylinder manufacturer founded in 1998, offering multiple cylinder types and customization from samples. It operates six production lines, reports annual hydraulic-cylinder output of 100,000 pieces, and exports to Southeast Asia, the Middle East, North America, and domestic markets. The supplier holds ISO9001:2015 certification and has documented procedures for inspection, supplier approval, corrective actions, and complaint handling, but records are not available for these procedures. R&D capability includes an available SDK, while manufacturing facilities include machining, welding, lathing, ultrasonic cleaning, painting, testing, and customer-requested destructive testing. Financial information is indicated for 2023–2025, but the provided slices do not disclose sufficient evidence to assess financial strength. Overseas service coverage is listed as zero, and the supplier has no Fortune 500 customer collaboration reported.

Supplier typeThe supplier is identified as Pinghu Tianlong Machinery Manufacturing Co., Ltd., an enterprise focused on the R&D, manufacturing, and sales of hydraulic cylinders. Its product keywords cover standard, telescopic, welded, nonstandard, servo-system, NFPA, construction, snow-plow, and other hydraulic-cylinder types.

CertificationsThe supplier holds an ISO9001:2015 certificate, explicitly reported in both the sustainability and management-system information. This provides direct evidence of certified quality-management-system coverage.

R&D capabilityThe supplier explicitly reports R&D capability with an available SDK and describes itself as conducting R&D in hydraulic cylinders. It also maintains multiple testing and manufacturing facilities, including customer-requested destructive testing, supporting product-development capability.

Production capacityThe supplier operates six production lines and reports annual hydraulic-cylinder output of 100,000 pieces. Its facilities include CNC machining, welding, lathing, ultrasonic cleaning, spray painting, two large-scale painting lines, five cylinder-testing units, and customer-requested destructive-testing equipment; however, it does not continuously reconcile quantities for every batch or production run.

Customization capabilityThe supplier explicitly offers customization from samples and provides destructive testing designed according to customer requests. Its broad hydraulic-cylinder product range and varied manufacturing facilities further support customized production.

Client casesThe supplier reports no collaboration with Fortune 500 companies. Although repeat buyers account for 50%–80% of its business, the slices do not identify specific customers or provide verifiable customer case details.
