& nbsp; The HMLC-2 low-pressure casting control system uses PLC as the lower control core and a human-machine interface as the upper monitoring and management machine to achieve automatic sequential action control of the low-pressure casting machine, real-time closed-loop feedback control of the liquid level pressure pouring process, and mold cooling control. It can also set and modify pouring process parameters, display pressure data and curves during the actual pouring process, and display machine working status and fault alarms. The control system has a high degree of automation, a fully Chinese interface, and a complete and friendly human-machine dialogue interface. The display is visual, functional, and easy to operate, providing strong support and guarantee for the operation and maintenance of low-pressure casting machines and the management of process parameters. & nbsp; The control function of HMLC-2 low-pressure casting control system is the same as HMLC-1.
