一般情况下,三金精密铸造加工精度受到了铸件构造、铸件材料、模具制作、制壳、培烧、浇筑等多方因素的影响的,在其中任何一个阶段设定、实际操作不科学都会让铸件的收缩率产生变化,造成铸件加工精度与规定有出入。以下属于可造成高精密铸件加工精度缺陷的要素:
(1)铸件构造的危害:铸件辟厚,收缩率人,铸件碎薄,收缩率小。随意收缩率大,阻拦收缩率小。
(2)铸件的材质危害:材料中含碳量越高,线收缩率越低,含碳量越小,线收缩率越多。
(3)模具制作对铸件线收缩率产生的影响:射蜡温度、射蜡工作压力、保压时间对精密铸造加工的尺寸危害以射蜡温度最为明显,次之为射蜡工作压力,保压时间在确保砂模铸造成形之后对砂模铸造最后的尺寸危害不大。
