假如浇注的温度过高的情况下，会引起一些缺点，例如晶体能变粗壮、会使铸件造成出气孔或者热裂和夹渣这些这种缺点。所以一般小型、厚度很薄的高精密铸件，它浇注温度在钢的熔点温度+150℃上下；浇注全面的构造一定要简易、且页面的规格比生铁大；一般大型厚度的铸件，它浇注温度会比它溶点温度高于100℃上下才能适合。
由于精密铸造的收拢远远地大于生铁，因此为了避免铸件发生缩松和铸造缺陷缺点，在铸造工艺设计上，壳型铸造加工厂家会使用直浇道、补贴和浇口这些对策来达到次序凝结。
壳型铸造批发为了避免铸件造成铸件常见的缺点，会一定要让铸件厚度维持匀称、防止斜角和直角构造，在金属型铸的型沙中加入木屑，在型芯中加入焦碳，及其选用一些中空型芯和油砂芯这些来改变砂模或者型芯的透气性能和退让性。
