To address issues such as high breakage rates and low production efficiency caused by insufficient demolding strength during block forming, we have developed an innovative process path based on vibration spectrum optimization. By integrating multi-frequency coupling technology combining high-frequency vibration and low-frequency compaction, along with real-time spectrum analysis and an adaptive control system, this method precisely matches the rheological properties of different materials and the requirements of each molding stage. It achieves uniform strengthening of the internal structure of blocks and reduces porosity. This process can increase block demolding strength by over 35%, shorten demolding time by 20%, while reducing mold wear and energy consumption. The solution is compatible with upgrades to existing production lines and has been validated through pilot and large-scale production tests, providing reliable technical support for high-quality block production.
