据联邦德国期刊《Aluminium》1987年第2期报道,日本采用挤压铸造技术生产变形铝合金铸件。所生产的铸件除了具有变形加工材料那样好的机械性能和焊接性能外,其成本比用变形加工材料制成零件的成本低。挤压铸造技术是将金属熔体浇注到坚硬的金属模内,并在高压下发生凝固。施加的高压 According to the Federal German periodical “Aluminum” No. 2 of 1987, Japan used extrusion die casting technology to produce deformed aluminum alloy castings. The resulting castings, besides having the same good mechanical properties and weldability as the textured materials, are less costly than the parts made from the textured materials. Squeeze casting technology is the metal melt poured into a hard metal mold, and under high pressure coagulation occurs. High pressure applied
