1.Accurate pressure stabilization control:The molding machine is equipped with a pressure sensor(accuracy±0.2MPa)and an electro-hydraulic proportional valve to monitor the pressing pressure in real time and feed it back to the system.If the pressure is lower than the set value(for example,from 12MPa to 11.5MPa),the system automatically increases the output of the hydraulic pump.If the pressure is too high(such as rising to 12.5MPa),it will automatically release the pressure to ensure that the pressure fluctuation throughout the pressing process is≤±0.3MPa,which is far superior to the±1MPa deviation of traditional manual control.
2.Automatic thickness calibration:The forming mold is equipped with an internal displacement sensor to detect the thickness of the sheet in real time(such as the target thickness of 12mm).If the thickness exceeds the standard(such as 12.3mm),the system immediately adjusts the pressing stroke(shortening by 0.3mm)to ensure that the thickness tolerance of a single sheet is≤±0.2mm.The consistency of thickness within the same batch is over 99%(while the consistency under traditional manual control is only 85).
3.Automatic process connection:The entire process from"slurry distribution→pressing→demolding→slab conveying"does not require manual intervention-the distribution system evenly spreads the material according to the preset area(such as 1.2mx2.4m),avoiding the problem of"local excessive thickness or excessive thinness"in manual distribution.After demolding,the slab is directly conveyed to the curing stage through an automated conveyor belt,reducing the"slab deformation and impact damage"caused by manual handling(the damage rate of traditional manual handling is 2-3).
