Slow injection speed of Aluminum Alloy Die-Casting The speed at which the aluminum alloy die-casting injection punch starts to move until the molten metal in the chamber is sent into the inner gate. In this stage, it is required to fill the pressure chamber with gold. Under the principle of not only reducing the temperature of the alloy liquid more, but also helping to eliminate the gas in the pressure chamber, it is necessary to try to choose a low injection speed, slow injection speed less than 0.3m/s, aluminum alloy die-casting fast injection speed, determined by the characteristics of aluminum alloy die-casting machines. The maximum injection speed given by domestic aluminum alloy die-casting machines is generally 4~5m/s (GB/T21269-2007 is currently set to 26~7m/s), while the speed of foreign die-casting machines is, Can reach 10m/s
