About the Company

随着科技的进步与铸造业的蓬勃发展,不同的铸造方法有不同的铸型准备内容。以应用*广泛的砂型铸造为例,铸型准备包括造型材料准备和造型、造芯两大项工作。砂型铸造中用来造型、造芯的各种原材料,如铸造原砂、型砂粘结剂和其他辅料,以及由它们配制成的型砂、芯砂、涂料等统称为造型材料,造型材料准备的任务是按照铸件的要求、金属的性质,选择合适的原砂、粘结剂和辅料,然后按一定的比例把它们混合成具有一定性能的型砂和芯砂。常用的混砂设备有碾轮式混砂机、逆流式混砂机和连续式混砂机。后者是专为混合化学自硬砂设计的,连续混合,混砂速度快。
造型、造芯是根据铸造工艺要求,在确定好造型方法,准备好造型材料的基础上进行的。铸件的精度和全部生产过程的经济效果,主要取决于这道工序。在很多现代化的铸造车间里,造型、造芯都实现了机械化或自动化。常用的砂型造型造芯设备有高、中、低压造型机、气冲造型机、无箱射压造型机、冷芯盒制芯机和热芯盒制芯机、覆膜砂制芯机等。
