Research on crystal discontinuity of low-pressure cast aluminum alloy wheels
Porosity is a very common defect in the casting process of low-pressure cast aluminum alloy wheels.As a part that carries the entire weight of the vehicle,the wheel is an important safety part,and it is particularly important to establish a reasonable defect inspection method.Penetrant inspection,FEA simulation,X-ray inspection,microscope inspection and other methods were used to inspect and analyze the porosity of low-pressure cast aluminum alloy wheels,and the cause of the problem was clarified.An analysis method for porosity of low-pressure cast aluminum alloy was established,which could effectively detect porosity defects and prevent defective wheels from entering the market.
