1、 Precision Die Casting Technology: The connecting parts of the aluminum alloy vehicle body frame structure are mostly formed by casting, and the casting methods used are mainly advanced high-precision die casting methods such as semi solid die casting. There are currently two forming processes for semi solid die casting: rheological forming and thixotropic forming. The former involves feeding liquid metal into a specially designed injection molding cylinder, applying shear by a screw device to cool it into a semi solid slurry, and then performing die casting. The latter is to feed solid metal particles or debris into a spiral injection molding machine, and under heating and shearing conditions, convert the metal particles into slurry before die casting. Due to excellent hydroforming performance and large design freedom, an hydroforming part can replace a workpiece formed by welding several parts, thereby avoiding distortion and deformation caused by welding, with high dimensional ac…
