As shown in the figure, after the die-casting mold is closed, the molten metal 3 is poured into the pressure chamber 2, and the injection punch 1 push ahead, the molten metal is pressed into the cavity 6 through the runner 7, and consolidation forming by cooling. When the mold is opened, the injection punch pushes out the residual material 10 to eject the castings through pushing out the ᱢᱮᱴᱨᱤᱠᱥ ᱫᱚ ᱢᱮᱴᱨᱤᱠᱥ ᱠᱟᱱᱟ, ᱡᱟᱦᱟᱸ ᱨᱮ ᱢᱮᱴᱨᱤᱠᱥ ᱫᱚ 1991 ᱨᱮᱭᱟᱜ ᱢᱤᱫ ᱢᱮᱴᱨᱤᱠᱥ ᱠᱟᱱᱟ ᱡᱟᱦᱟᱸ ᱫᱚ ᱢᱤᱫ ᱢᱮᱴᱨᱤᱠᱥ ᱠᱟᱱᱟ ᱡᱟᱦᱟᱸ ᱫᱚ ᱢᱩᱪᱟᱹᱫ ᱨᱮ ᱢᱤᱫ ᱵᱟᱝ ᱵᱟᱹᱲᱤᱡ ᱜᱮᱭᱟ᱾

In the first stage, the injection punch pushes the molten metal at a slow speed, so that the molten metal fills the front of the pressure chamber and accumulates at the front edge of the inner pouring gate. At this stage, the air in the pressure chamber will has a sufficient period of time to be escaped, also the molten metal is prevented from being splashed from the pouring gate.

During the die casting filling process, the advancement speed of the injection punch directly affects the quality of the casting. As shown in the figure below, when the injection punch speed is too high or too low(1)(2) in the first stage, it is not conducive to the quality of the casting. In order to effectively eliminate the problem of hidden gas in the die casting, the injection punch can adopt uniform acceleration motion at this stage, that is, when ᱡᱩᱫᱤ 35 kg ko ko ko ko ko ko ko jạruṛ ge jạruṛ ge kạmi lạgit̕ kana, ᱢᱮᱱᱠᱷᱟᱱ ᱱᱚᱶᱟ ᱠᱷᱚᱱ ᱵᱟᱹᱲᱛᱤ ᱫᱚ ᱵᱟᱝ ᱧᱮᱞᱚᱜ-ᱟ (megep virtion i) ᱢᱮᱱᱠᱷᱟᱱ ᱚᱱᱟ ᱠᱷᱚᱱ ᱵᱟᱹᱲᱛᱤ ᱫᱚ ᱵᱟᱝ ᱧᱮᱞᱚᱜ-ᱟ ᱾
