Aluminum alloy die casting product

Shrinkage occurs when the temperature of molten metal decreases. When the temperature of molten metal decreases, the surface and internal temperatures do not decrease at the same time. The surface layer of molten metal cools very quickly, and then the internal temperature decreases. It can be seen from this that the liquid metal begins to condense from the surface, and the internal part slightly lags behind the condensation circle and contracts. If the metal liquid is not added to the inside of the die casting during the quenching process, the shrinkage cavity will occur. The shrinkage metal flow is to increase the pressure in the high pressure chamber immediately before the metal liquid at the inner gate is solidified, and to add the metal liquid into the mold cavity to the ideal die casting, it should be added and compressed immediately after the metal liquid is filled and before it is fully solidified. The better the quality of the die casting is when the feeding metal flow plays…
