What about the pressure difference of vacuum molding machine?

The pressure difference of vacuum molding machine generally refers to the low pressure of vacuum pump. If the pressure is low at the beginning, it is very likely that the appropriate vacuum pump model was selected incorrectly when selecting the model; If the pressure gradually decreases later, it may be that there are too many impurities in the vacuum pump, which may be blocked after long-term use, so it is necessary to clean up the internal impurities.
We should also consider whether the suction is slow or the air pressure is slow. If the suction is slow, check whether the vacuum pump is damaged. If the vacuum pump is not damaged, check whether the switch of the pipeline is broken and whether the vacuum valve is broken.
