The frozen index assigns 227 companies to Metal Systems, including 169 in China, 21 in Korea and 16 in Japan. The 20 selections cover metal equipment and related production businesses. The category count locates potential suppliers; it does not establish delivered output or qualification across the group. BLT and Farsoon are listed suppliers, while Eplus3D's STAR Market IPO review ended after withdrawal on March 24, 2026. BLT's 2024 annual report records revenue of RMB1.326 billion, up 15.02% against the restated 2023 figure. Net profit attributable to shareholders fell 5.26%. Revenue growth therefore needs to be assessed alongside profitability, rather than presented as a general proof of production maturity. For a sourcing decision, separate equipment capability from the operating model of the supplier. Compare the required material, build envelope, validated parameters, post-processing, delivered throughput and local support. A large build chamber or a public listing alone does not demonstrate that a particular part meets its acceptance criteria. The 22% recorded as founded since 2019 is a cohort descriptor, not a measure of readiness.
