Have you ever seen wall panels for buildings are made like buns? After sending materials into an unmanned factory, like the dough-making process, a worker in the control room just needs to press a button, and then wall panels are churned out like steaming buns.

This high-tech enterprise in Hunan uses autoclaved thermal insulation block technologies and relies on photovoltaic power generation and a complete recycling system for wastewater, exhaust gas, and waste residues to produce aerated concrete panels. This innovative production leads Changsha's construction industry toward industrialization, digitalization, intelligence, and green transformation.
