1可以生产形状复杂的零件，尤其复杂内腔的毛坯(如暖气)

2适应性广，工业常用的金属材料均可铸造。 几克~几百吨。

3原材料来源广泛。价格低廉。 废钢，废件，切屑

4铸件的形状尺寸与零件非常接近，减少切削量，属少无切削加工

1. It can produce parts with complex shapes, especially blanks with complex inner cavities (such as heating)

2. Wide adaptability, metal materials commonly used in industry can be cast. A few grams to hundreds of tons.

3. The source of raw materials is extensive. Low price. Scrap

4. The shape and size of the casting are very close to the parts, and the cutting amount is reduced, which belongs to less non-cutting processing
