The 3D needle punching machine independently developed by Yunlu Composite Materials optimizes the ratio of raw materials for prefabricated bodies by combining needle punching with various processes, achieving precise control of the bulk density value of prefabricated bodies and effectively reducing subsequent deposition and machining costs. Through the automation and collaborative control of multiple processes such as continuous feeding, needle punching, composite technology, cutting, baking, inspection, and packaging, the entire process of automated production has been achieved, significantly improving production efficiency. Based on AI technology, the system adopts intelligent formula modes such as automatic matching and automatic needle withdrawal, which can automatically call and execute process formulas, reduce dependence on manual skills, and significantly improve per capita production capacity. Relying on a fully self-developed acupuncture big data control system, the process data is deeply integrated with equipment parameters, achieving comprehensive data-driven management of equipment and production lines, further improving product qualification rates and quality consistency.
