AI-Powered supplier vetting

SummaryThe supplier is identified as a Chinese manufacturer established in 2009, with 75 employees and a 3,000 m² manufacturing facility. Its stated products include flexible, grid, disc, gear, jaw, tyre, and other couplings, as well as shaft-transmission components; another description references screw pumps for oil and other high-viscosity fluids. Production evidence includes more than 10 production lines and stated coupling output of 3,000 tons. The supplier reports ISO9001:2008 and OHSAS18001:2007 certifications, four R&D engineers, and high-precision production and testing equipment. It exports to Russia, Europe, the United States, and Southeast Asia, although the export-sales proportion is stated as 11%–20%. Evidence is insufficient to assess after-sales service, financial credibility, customization capability, or specific customer cases.

Supplier typeThe supplier is explicitly described as a factory and manufacturer, legally organized as a limited company in China. This directly confirms that it operates as a manufacturing supplier rather than only a trading entity.

CertificationsThe supplier reports ISO9001:2008 and OHSAS18001:2007 certificates, along with other unspecified certifications. These stated management-system certifications provide explicit evidence supporting this field.

R&D capabilityThe supplier reports high-precision and advanced production and testing equipment and has four R&D engineers. These facts support technical development and process capability, but no information confirms patented products, proprietary technologies, or new-product development outcomes.

Production capacityThe supplier has 75 employees, a 3,000 m² manufacturing plant, more than 10 production lines, and stated coupling production of 3,000 tons. These explicit capacity indicators support an established production operation for coupling-related products.
