How to process the Alloy filling

With high pressure and high speed filling, the metal liquid will have severe impact and erosion on the mold, so mechanical stress and thermal stress will occur.In the impact process, the metal liquid, impurities, gas will also have complex chemical effects with the mold appearance, and accelerate the erosion and crack initiation.When the liquid metal is gas, low pressure area in the cavity expansion first, when the gas pressure, blasting introversion, pull out of the cavity surface of the metal particle and formation damage, cracks occur due to cavitation.
