What is the reason for the exhaust pressure of the aluminum alloy extrusion machine to be exhausted?

Look at the way to control the exhaust. If you use a pressure relay, you can increase it appropriately; if you use a pressure transmitter, you can modify and increase the exhaust pressure on the man-machine interface. It is mainly aimed at the extruder that used to be normal. If it is a new machine, there may be procedural problems. Suggestion: Non-professional operators of extrusion machines should not change and understand the programs in the machine.
