液态金属浇注到与零件形状、尺寸相适应的铸型型腔中，待其冷却凝固，以获得毛坯或零件的生产方法，通常称为金属液态成形或铸造。
Liquid metal is poured into the mold cavity corresponding to the shape and size of the part, and then it is cooled and solidified to obtain the production method of blank or part, which is usually called liquid metal forming or casting.
工艺流程：液体金属→充型→凝固收缩→铸件
Process flow: liquid metal → filling → solidification shrinkage → casting
工艺特点：
