Castings are mainly used as blanks for machine parts, and some precision castings can also be used directly as machine parts. Casting occupies an age proportion of mechanical products. for example, in tracks, the weight of castings accounts for about50-70% of the weight of the whole machine, 40-70% in agricultural machinery, and 70-0% in machine tools and internal combustion engines. Among all kinds of castings, mechanical castings have the most varieties, the most complex shapes, and the agest amount accounting for about 60% of the total casting output.
