When sourcing a ceramic plate making machine, you must prioritize production capacity (pieces per hour) and forming technology. Common methods include Roller Head Forming for round plates and Isostatic Pressing for high-density, complex shapes. Ensure the machine supports the maximum diameter and thickness of the plates you intend to produce. Additionally, check for PLC control systems (like Siemens or Delta) to ensure automated precision and vacuum pug mill integration to eliminate air bubbles in the clay, which prevents cracking during firing.
