It reports four production lines, multiple large extrusion machines, supporting finishing processes, 6–10 R&D engineers, and 6–10 quality-control staff. The supplier states that it offers customized OEM/ODM services and integrated processing from tooling design through packaging. ISO 9000, ISO 9001, and ISO 14064 certifications are listed. Export activity is substantial according to the provided profile, with self-operated import/export rights, export experience since 2016, and broad global market coverage. Reported delivery times are within 15 working days off-peak and one month during peak periods. The available trade records show two transactions with one Mexican buyer in May 2025; these records provide limited customer-case evidence. No financial figures are included in this assessment.

Supplier typeThe supplier is explicitly identified as a factory and Manufacturer/Factory, operating as Hunan Lang Le Technology Co., Ltd. in Changsha, Hunan, China. This directly supports classification as a manufacturing supplier rather than a trading-only entity.

CertificationsThe supplier lists ISO 9000, ISO 9001, and ISO 14064 as supplier management-system certifications. These stated certifications provide explicit evidence of formal quality and management-system credentials, although the slices do not provide certificate validity dates or scopes.

R&D capabilityThe supplier reports 6–10 years of total R&D-engineer experience and describes ongoing system improvement. It also operates large extrusion equipment and several finishing lines, but the slices do not provide patents, proprietary technologies, new-product data, or quantified R&D investment.

Production capacityThe supplier reports four production lines, several large extrusion machines with capacities of 800, 1800, 2500, and 3600 tons, and supporting oxidizing, battery, flame-plating, and sand-blasting lines. It also states delivery capability of within 15 working days off-peak and one month during peak periods, providing explicit evidence of established production capacity.

Customization capabilityThe supplier explicitly welcomes customized designs, accepts OEM orders, and offers OEM/ODM aluminum extrusion services. Its stated process coverage from tooling design through extrusion, assembly, cutting, drilling, threading, and packaging supports end-to-end customization capability.

Client casesThe available trade records show two May 2025 transactions involving one Mexican buyer, GLOBAL INTEGRAL SERVICES SA DE CV, for a drilling screw and an aluminum-zinc alloy hinge. This confirms at least one identifiable overseas buyer relationship, but the limited number of records does not demonstrate a broad or extensive customer portfolio.
