AI-Powered supplier vetting
SummaryRizhao Junrui Trading Co., Ltd is identified as both a trading company and manufacturer/factory in China, offering hydraulic cylinders, pumps, power units, and related components. The supplier reports multiple dedicated hydraulic, tank, pipe, cold-processing, and stamping production lines, plus more than 600 employees in one company description; however, another slice states only three total employees, creating a material inconsistency. It provides OEM and extensive customization services and generates 71%–90% of sales from exports, with six years of export experience and self-operated import/export rights. Innovation evidence is limited: no SDK is available, only one R&D engineer is reported, and R&D audit documentation is unavailable. No overseas showrooms, agents, branches, or offline trade-show participation are reported. Financial data only identifies years, not financial performance, so credibility cannot be assessed. No customer cases or certifications are provided.
Supplier typeThe supplier is described as both a trading company and manufacturer/factory, while its company type is also listed as a trading company. Its stated business scope covers hydraulic cylinders, mine columns, jacks, hydraulic components, systems, pump stations, and related metal and plastic products. This indicates a mixed trading-and-manufacturing profile, although the records are not fully consistent.
R&D capabilityThe supplier describes hydraulic R&D and an engineering team providing technical support, but reports no available SDK, only one R&D engineer, and no R&D audit documentation covering design inputs, outputs, reviews, verification, or validation. These records show some technical capability but do not establish strong innovation systems.
Production capacityThe supplier reports four high-pressure hydraulic-cylinder lines, two coal-machine cylinder lines, one telescopic-cylinder line, one high-pressure oil-pipe line, two construction-machinery tank lines, four agricultural-machinery tank cold-processing lines, and an advanced stamping workshop. It also states that it has multiple hydraulic and power-unit workshops, but the reported employee count conflicts sharply between more than 600 and three; production scale is therefore supported by claimed facilities but not fully consistent across records.
Customization capabilityThe supplier explicitly provides OEM services for well-known brands and supports customization from samples, designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
