砂型铸件 sand casting 用砂型铸造法生产的铸件。同样，其他铸造方法生产的铸件可相应称为压铸件、离心铸件、熔模铸件等。
砂型铸件上可能发现下列哪种缺陷？
Which of the following is a discontinuity which might be found in sand castings?
结果表明，与砂型铸件相比，消失模法生产的铸件尺寸精度及质量提高，工艺出品率提高到65%以上。
Results showed that compared with sand casting castings, dimension precision and quality of lost pattern castings can be improved and rate of finished products can be increased up to65percent.
随着新的铸造工艺的不断出现，未来砂型铸件的产量可能会有所减少，但是专家断言，绝大部分铸件依然要靠砂型工艺进行生产。
Although sand casting production may decrease with new casting technologies emerging, it is asserted that the vast majority of castings would have to be produced by sand casting technology.
