Antimony adds to the rigidity of the casting . 銻能增加鑄件的硬度。
It's used for the production of large castings . 它用于大型鑄件的制備。
Any out-of-adjustment pins can be reason for casting rejection . 如果頂釘調整不當,可能使鑄件報廢。
Ribs are sometimes add to the webs of castings to give greater strength and rigidity . 有時在鑄件的腹板上加上肋條,以增強其強度和剛度。
Multi-cavity molds are sometimes provided with knock-out pins for easy ejection of the casting from the molds . 多腔模具有時裝有頂釘,以便鑄件易于脫模。
All lead castings were produced at first by hand in many cases from single cavity molds . 起初所有的鉛鑄件都是手工生產的,而且在許多情況下都是使用單腔模具。
By such addition of the cellulosic material, an explosive cast is achieved having greater mechanical strength . 由于加入這種纖維質物質,炸藥鑄件具有較高的機械強度。
The temperature of the lead should be such that it is just enough to produce satisfactory castings in a heat-stabilized mold . 鉛液的溫度要正好適宜于在熱穩定的模具中鑄出合格鑄件。
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 . 中間的單元帶著板柵鑄件從模具通過整修模,最后從傳送帶上將它置落到收集架上。
