Why low-pressure casting aluminum alloy commonly used?
3. Because it is through the automatic pressure casting, it is easy to automate, reduce labor intensity;
4. Low pressure casting castings can be heat-treated.
Given these advantages, it is commonly used in low-pressure aluminum casting.
1. By pressure die-casting from the molten aluminum holding furnace into the mold cavity, the cavity filled with liquid aluminum speed controllable, continue to maintain a certain pressure after filling the cavity, so that solidification of molten aluminum under pressure, so the casting dense, no shrinkage and porosity;
Because of its low melting point, while the low-pressure casting has the following advantages:2. Since casting is under pressure in order from top to bottom of the solidification, so no riser, metal utilization is high;
