automobile has become the most important tool for human beings to travel, and commuting, travelling and traveling are more convenient and convenient. But you know, a complete car has many parts, and aluminum castings have become the most used parts of the whole car.

    aluminum castings in cars can be cast by low pressure casting. Low pressure casting is a casting reverse method between pressure casting and gravity casting. Its basic principle is that in the crucible with metal liquid, the dry compressed air or inert gas is placed on the surface of the metal liquid at a certain temperature, so that the metal liquid is entered into the cavity through the runner from the bottom to the top of the lift pipe, and the pressure is increased after the metal liquid is filled with the cavity, and the gas pressure on the liquid surface is kept to the casting. The workpiece is completely solidified, and then the contact pressure causes the solidified metal in the riser and runner to fall back into the crucible, that is, a low pressure casting process is completed.

    Hangzhou Hongcheng Pml Precision Mechanism Ltd is an aluminum casting and aluminum foundry manufacturer, casting aluminum alloy through low pressure casting process. And Xiaobian together to see the advantages of low pressure cast aluminum.

    1. liquid metal aluminum filling is relatively stable;

    2. aluminum castings are good in formability, which is beneficial to the formation of clear and smooth surface of the castings, which is more favorable for the forming of large thin-walled aluminum castings;

    3. aluminum castings have compact structure and high mechanical properties;

    4. improved the processing rate of the metal liquid. In general, no riser is needed, so the rate of the metal liquid is greatly improved, and it can generally reach 90%
