蜡(模)料的线收缩率大约为0.9-1.1%；熔模储放时，将进一步造成收拢，不锈钢精密铸造厂商发现其伸缩值大约为总收拢量10%，但是当储放12小时，熔模规格基本上平稳；蜡模轴向收缩率仅是长短方位收缩率的30-40%，射蜡温度对随意收缩率的影响远大于对遇阻收缩率的影响(射蜡温度为57-59℃，温度越大收拢越多)。
制壳原材料的影响，选用锆矿、锆英粉、上店砂、上店粉，以其热膨胀系数小，仅是4.6×10-6/℃，因而是忽略不计。
型壳培烧的影响，因为型壳热膨胀系数小，当型壳温度为1150℃时，仅是0.053%，所以也是忽略不计。
不锈钢精密铸造加工温度的影响，浇筑温度越大，收缩率越多，浇筑温度低，收缩率越低，因而浇筑温度尽可能。
