| 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： Process characteristics: 1、可生产形状任意复杂的制件，特别是内腔形状复杂的制件。 1. It can produce any complex parts, especially the parts with complex inner cavity shape. 2、适应性强，合金种类不受限制，铸件大小几乎不受限制。 2. It has strong adaptability, unlimited alloy types and almost unlimited casting size. 3、材料来源广，废品可重熔，设备投资低。 3. The material source is wide, the waste products can be remelted, and the equipment investment is low. 4、废品率高、表面质量较低、劳动条件差。 4. High scrap rate, low surface quality and poor working conditions. |
