粒筛网目数的正确的选择：精密铸造钢件构造繁琐，有深窄的间隙或孔眼，因为撒砂过粗，以至这样的地方被堵住，促使浸浆不够，可能会导致型壳不高密度，一部分地区壳比较薄，抗压强度降低。
对应措施：在浸浆以前，首先用气动枪把最上层浮砂吹除，然后可以直接过一遍硅溶胶，再浸浆，这可以提升浆体的流通性，避免阻塞状况。作业员在浮砂以后，能用细棒通一通圆洞、间隙处堆砂，也有助于以后的浸浆上砂。除此之外，对于浅孔产品，可以从三层以后往孔里注浆填砂，为此避免浅孔内腔漏铁。
壳型精密铸造模壳干躁不透光，会导致壳抗压强度大幅度下降。并且缘故乃是生产车间温度湿度欠佳，促使干燥时间不充足。
对应措施：操纵生产车间温度湿度，结合实际情况调节。
