AI-Powered supplier vetting

SummaryHunan Lang Le Technology Co., Ltd. is identified as a Chinese manufacturer/factory specializing in aluminum extrusion, profiles, brackets, workbenches, conveyors, and related products. It reports ISO 9000, ISO 9001, and ISO 14064 certifications, four production lines, multiple large extrusion machines, and supporting processes including oxidizing, battery, flame-plating, and sand-blasting. The supplier states that it provides OEM/ODM, tooling design, extrusion, assembly, cutting, drilling, threading, and packaging services. Export activity is substantial in the provided data, with self-managed import/export rights, exports beginning in 2016, and broad global markets. However, the available customer-case evidence is limited to two single recorded transactions involving one buyer, and the slices do not provide sufficient evidence to assess after-sales service or financial credibility.

Supplier typeThe supplier is explicitly classified as a factory and Manufacturer/Factory, with a limited-company structure and operations in Changsha, Hunan, China. This directly supports its status as a manufacturing supplier rather than only a trading intermediary.

CertificationsThe supplier reports holding ISO 9000, ISO 9001, and ISO 14064 management-system certifications. These stated certifications provide explicit evidence of formal quality and environmental-management system coverage.

R&D capabilityThe supplier reports 6–10 years of total R&D-engineer experience, OEM/ODM support, customized extrusion design, several large extrusion machines, and ongoing process-system improvement. These details explicitly support product-development and engineering capability, although no specific patents or new-product results are provided.

Production capacityThe supplier reports four production lines, large extrusion machines ranging from 800 to 3600 tons, and additional oxidizing, battery, flame-plating, and sand-blasting lines. It also states off-peak lead times within 15 working days and peak fulfillment within one month, providing direct evidence of established production capacity and process coverage.

Customization capabilityThe supplier explicitly accepts customized designs and OEM/ODM orders for aluminum extrusions, and describes tooling design, extrusion production, assembly, cutting, drilling, threading, and packaging services. Its product keywords also include T-slot, V-slot, aluminum profiles, workbenches, and angle brackets, reinforcing the relevance of its customization scope.
