Abstract：
In order to improve the production efficiency and product quality of ductile iron thin-wall pipe fitting with DISA line,taking tee pipe as an example,the mould design of thin-wall pipe fitting with DISA vertical modeling line was optimized again,and the mould layout and the design method of casting system were expounded.The results show that the production efficiency of the optimized tees increases by 100%according to the new process test.There is no shrinkage cavity or porosity defects in the casting,and the rejection rate is controlled below 2%,which has successfully realized the large-scale mechanized production of the thin-walled pipe fitting.
