不同研究组得出的喷射成形工艺的模型相互间以及与实际工艺均显示出合理的一致性。利用这些模型就可对喷射成形中涉及的几个复杂过程提供深刻的解释,另外,这些模型还可用来设计实验以便更深入地洞察工艺过程。本文所叙述的工作,业已表明喷射中液体模拟系数f_1(s)可视作是一种合理控制喷射成形的参数。已经发现粘结效果和气孔率都与f_1(s)有密切关系。对于坯锭喷射时液体系数最佳值为(0.3)而对钢管为(0.5—0.6),这之间的差别表明实际控制参数可能是喷射时沉积在表面上的液体系数f_1(d.。本文还讨论了尤其需要改进在复杂几何形状体上整个热分布剖面的模型,如喷射沉积管。因为这对实际喷射成形过程中的一些特征如液滴尺寸,速度和沉积温度的直接实验测量中改进工艺诊断方法是很有价值的。
