The specific steps of nitrogen filling are as follows:

1) Before nitrogen is filled, sufficient nitrogen should be prepared according to the tonnage of the die casting machine.

2) Prepare tools to fill with nitrogen

3) Check whether the nitrogen bottle is filled with nitrogen before filling.

4) Test the pressure of nitrogen storage cylinders one by one with a pressure gauge and record it. In order to save nitrogen, low cylinder pressure to high cylinder pressure is generally used when filling nitrogen. For the die casting machine, the first step is to fill the fast energy accumulator first, and then to fill the pressurized energy accumulator.

In the whole injection process, the best indicator to measure the performance of a die casting machine is the rapid injection, and this is closely related to the pressure of fast nitrogen. According to the whole injection process, the most commonly used is the fast nitrogen accumulator, so relatively speaking, the nitrogen pressure of the fast energy accumulator is slightly higher than that of the pressurized energy accumulator.
