AI-Powered supplier vetting

SummaryNingbo RXHLi Technology Co., Ltd. is presented as a water-treatment membrane manufacturer with UF and RO-related production lines, testing facilities, and 30 quality inspectors. It holds ISO9001:2015 and ISO14001:2015 certificates and reports written supplier-service procedures, corrective-action records, and finished-product inspection instructions. The supplier offers 3D design, sample/design-based customization, full customization, ODM, and OEM services, and reports new products within the past year. It has exported for seven years, with exports representing 11%–20% of total sales, but reports no overseas warehouses, showrooms, agents, or branches. The evidence does not establish financial credibility, named customer cases, or a complete after-sales service program. It also reports no SDK availability and no established AI model for data-driven management.

Supplier typeThe supplier is identified as Ningbo RXHLi Technology Co., Ltd. and describes itself as a water-treatment membrane manufacturing base with UF membrane and RO flat-sheet production lines, rolling equipment, water-testing equipment, and a laboratory. Its export activity includes agency and self-operated export channels and has continued for seven years, indicating a manufacturer with international trading capability.

CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates. These explicitly demonstrate quality-management and environmental-management system certification.

R&D capabilityThe supplier reports 3D software design services, new products within the past year, ODM capability, and broad customization support. However, it reports no available SDK and no established AI model for big-data decision support, so innovation capability is demonstrated in product development and design but not across all stated technology dimensions.

Production capacityThe supplier reports six German-imported reverse-osmosis membrane production lines, UF and RO flat-sheet lines, domestic and industrial rolling machines, water-testing equipment, and a laboratory, supported by 30 quality inspectors and standardized finished-product inspection instructions. These details explicitly support substantial manufacturing and quality-control capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, flexible customization, and minor customization, together with 3D software design services. This indicates broad ability to support both design-led and sample-led customization.

Q:RTLwith around 300 workers in the factory.

RTL technical advantage lies in the high desalination technology, and the process of coating polyamide is different from its counterparts. Therefore, in the use of household membranes, according to market feedback, it can be applied to 3,000-6,000 ppm water quality. Seawater membrane can be applied in the environment of 30,000-40,000ppm, and the cost advantage is very obvious.

Q:If quality problem,what is your guarantee terms?

At present, we maintain zero customer complaints on products. Please note that the first item of our company's values: Do not let customers count one copper coin.
