Antimony adds to the rigidity of the casting . 锑能增加铸件的硬度。
It's used for the production of large castings . 它用于大型铸件的制备。
Any out-of-adjustment pins can be reason for casting rejection . 如果顶钉调整不当，可能使铸件报废。
Ribs are sometimes add to the webs of castings to give greater strength and rigidity . 有时在铸件的腹板上加上肋条，以增强其强度和刚度。
Multi-cavity molds are sometimes provided with knock-out pins for easy ejection of the casting from the molds . 多腔模具有时装有顶钉，以便铸件易于脱模。
All lead castings were produced at first by hand in many cases from single cavity molds . 起初所有的铅铸件都是手工生产的，而且在许多情况下都是使用单腔模具。
By such addition of the cellulosic material, an explosive cast is achieved having greater mechanical strength . 由于加入这种纤维质物质，炸药铸件具有较高的机械强度。
The temperature of the lead should be such that it is just enough to produce satisfactory castings in a heat-stabilized mold . 铅液的温度要正好适宜于在热稳定的模具中铸出合格铸件。
The center unit carries the grid casting from the mold through the trimming die and finally drops it off the conveyor to a collecting tray . 中间的单元带着板栅铸件从模具通过整修模，最后从传送带上将它置落到收集架上。
