AI-Powered supplier vetting

SummarySOV Hydraulic Technology (Shanghai) Co., Ltd. is identified as a China-based trading company established in 2012, with 12 employees and operations associated with Shanghai. Its stated product range covers hydraulic cylinders, jacks, torque tools, pumps, synchronous lifting systems, bolt tensioners, pipe benders, and related equipment. The supplied information indicates three production lines, 6–10 quality-control staff, and export coverage across multiple regions, but no supplier management-system certification is reported. The company describes applications in steel, cement, chemical, refinery, bridge, railway, and other industrial projects, including synchronous hydraulic systems used in China high-speed railway construction. Evidence is insufficient to verify after-sales capability, financial credibility, customization capability, or a broad independently documented customer base.

Supplier typeThe supplier is explicitly classified as a trading company or limited trading entity, headquartered in Shanghai, China, with a stated factory location in Taizhou, Jiangsu. This indicates a trading-led business structure with identified production-related facilities, but the materials do not establish that it is primarily a manufacturer.

CertificationsThe supplier management-system certification field is explicitly reported as "NIL." No qualifying certification is evidenced in the provided information, representing a stated gap in this field.

R&D capabilityThe supplier describes a synchronous PLC hydraulic system used in China high-speed railway construction and integrated multi-point hydraulic lifting solutions for house translation, leveling, bridge support, and tank welding support. These stated system solutions provide evidence of technical development and application capability.

Production capacityThe supplier reports three production lines, 6–10 quality-control staff, and a factory location in Taizhou, Jiangsu, while also stating order fulfillment within 15 working days in both peak and off-peak periods. These details support an identifiable production and fulfillment capability, although the supplier is also classified as a trading company.

Client casesThe supplier cites use of its synchronous PLC hydraulic system in China high-speed railway construction and states that its products have been used in steel plants, cement, chemical and refinery facilities, bridges, and railway construction and maintenance. These are stated application references, although named customers or independently verifiable case details are not provided.
