[Successful Trial Production of Wuling Industry's Magnesium Alloy Semi-solid CCB] The length of the magnesium alloy cross car beam (CCB) product trial-produced this time exceeds 1.5 meters, with a single magnesium alloy injection volume exceeding 8kg, and the finished product weighing only 4.6kg. By utilizing a magnesium alloy injection molding machine and semi-solid forming process, the product's performance has been significantly improved: 1) Optimized tissue density, with fine grains and no dendritic structure, resulting in a 10%-20% increase in tensile strength compared to traditional processes; 2) Extended fatigue life; 3) Superior corrosion resistance compared to traditional high-pressure casting; 4) Effectively resolved casting defects such as shrinkage porosity and blowholes.
