2018-12-27Because of the insufficient air cooling at the exit of extruder, aluminum profile contacts the swing bed at a higher temperature. The cooling speed of contact part is different from other positions, and there is coarse Mg2Si phase precipitation, which turns black gray after anodizing.
2018-11-26Spray forming is a process of atomizing the liquid flow of alloy into small droplets by high pressure inert gas, flying and cooling in high-speed air flow, and depositing into blank before it has not yet been completely solidified. It has the advantages of fine grain, uniform structure, and can restrain macro segregation, and has the advantages of one step from alloy melting to near final forming, which has attracted great attention.
