用一道工序将砂型制造环节的模具制作、造型、造芯、合箱四道工序全部替代,铸件质量和生产效率大幅提高,精度从最高正负1毫米提高到0.2毫米左右。铸造业“老大难”发动机缸头生产的废品率也从平均30%降到5%以内,中速柴油机机体的生产时间则由8天缩至1天。2016年2月2日,国务院总理李克强考察共享集团时称,3D打印实现了铸造产品从“傻大黑粗”到“窈窕淑女”的转变。指出,用颠覆性新技术改造传统产业大有空间。
With a process of sand mold manufacturing process will be made, modeling, making the core, all four cases of the box instead of replacement, casting quality and production efficiency increased significantly from the highest plus or minus 1 mm to 0.2 mm or so. In the foundry industry, the scrap rate of the production of engine crankshaft was also reduced from an average of 30% to less than 5% while that of medium-speed diesel engine body was reduced from 8 days to 1 day. February 2, 2016, State Department Premier Li Keqiang visited the sharing group, said that 3D printing has realized the transformation of foundry products from “stupid” to “stupid lady”. Pointed out that there is plenty of room for transforming traditional industries with disruptive new technologies.
