砂型铸造是当今铸造业中使用最普遍的铸造工艺，适用于各种材质，铁合金，非铁合金铸造都能用砂型铸造。可以生产从几十克到几十吨，及更大的铸造件。砂型铸造的不足之处是：只能生产结构相对简单的铸件。砂型铸造最大的优势是：生产成本低。但在表扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训面光洁度、铸件金相，内部密度相对较低。在造型方面，可手工造型，亦可机器造型。手工造型适用于单件、小批量和难以使用造型机的形状复杂的大型铸件。机器造型可大幅度提高表面精度和尺寸精度，但投资较大。
Sand casting is the most commonly used casting process in today's casting industry. It can be used for all kinds of materials, ferroalloys and non ferroalloys. It can produce castings from tens of grams to tens of tons and larger. The disadvantage of sand casting is that it can only produce castings with relatively simple structure. The biggest advantage of sand casting is low production cost. However, in surface finish, casting metallography, internal density is relatively low. In terms of modeling, it can be done by hand or by machine. Manual molding is suitable for single piece, small batch and large castings with complex shape which are difficult to use molding machine. Machine modeling can greatly improve the surface accuracy and dimensional accuracy, but the investment is large
