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.
