A study was made of the contraction of the Silver-Indium alloy due to the difference of the casting condition, by mean of the quartz pipe, whose thermal-expansion coefficient was very small. The results were as follows. 1) The higher the mold temperature, the smaller the casting shrinkage. 2) When the casting pressure was extremely low the casting shrinkage was great. But if the casting pressure was over 0.16 kg/cm2, the casting shrinkage didn't change. 3) The bigger the sprue size, the smaller the casting shrinkage. 4) The casting temperature of the alloy, the cooling system, the amount of the metal and the form of the wax pattern showed that the casting shrinkage remain the same.
通过热膨胀系数非常小的石英管，对银铟合金因铸造条件不同而产生的收缩进行了研究。结果如下：1）铸型温度越高，铸造收缩越小。2）当铸造压力极低时，铸造收缩很大。但如果铸造压力超过0.16kg/cm²，铸造收缩就不会改变。3）浇口尺寸越大，铸造收缩越小。4）合金的铸造温度、冷却系统、金属量和蜡模形状表明铸造收缩保持不变。
