AI-Powered supplier vetting

SummaryNanjing Kairong Machinery Tech. Co., Ltd. is identified as a China-based limited company and trade company engaged in manufacturing and processing machinery, particularly extruders and plastic recycling equipment. The supplier reports 200 twin screw extruders of annual output, five production lines, and 6–10 quality-control staff. It describes design, manufacturing, commissioning, packing, and after-sales capabilities, and states that it provides whole-plant and turnkey solutions. Export activity began in 2015, with 41%–50% of sales reportedly from exports, and customer locations are listed across several countries. However, the evidence does not establish any certifications, provides only limited direct customer-case detail, and indicates just one total R&D engineer. The supplier’s legal identity, operating location, product scope, and production information are documented, but several capability areas remain only partially evidenced.

Supplier typeThe supplier is identified as Nanjing Kairong Machinery Tech. Co., Ltd., a China-based limited company with a combined business entity type. It is described as a trade company, while its commercial engagement is manufacturing and processing machinery, indicating a mixed trading and machinery-supply profile.

After-Sales capabilityThe supplier explicitly states that it provides after-sales service and has aftersales staff, while also describing service as a quality objective. These statements support the existence of an after-sales function, although no staffing detail, response standard, or service performance evidence is provided.

Production capacityThe supplier reports annual production of 200 twin screw extruder sets, operates five production lines, and has 6–10 quality-control staff. A stated factory location and manufacturing plant area further support production activity, although the reported workforce size is small and capacity details are limited to the listed product output.

Customization capabilityThe supplier states that it develops new designs and offers solutions designed to meet different customer requirements, including whole-plant and turnkey solutions. This directly supports customization and project-solution capability, though no specific customized project examples or technical scope are supplied.

Product Q&A

Q:What materials are used for the screw and barrel?
