Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.

MARC存在的粉末材料模型方面的设计缺陷后，对连铸水口粉末成形件的变形规律及影响因素作用进行了模拟分析，指出芯棒形状对成形件的变形有较大影响，并且芯棒顶部形状与芯棒底部形状相比，对粉末变形有更大影响；(3)分析了成形件出现低密度区域的原因，指出模具形状对粉末流动以及粉末成形件低密度区域的形成有重要作用，提出了密度分布优化改进模型：改进模具顶部形状，并将芯棒顶部设计成球面后，粉末成形件顶部区域的应力、应变分布更加均匀、合理，粉体颗粒流动情况明显改善，低密度区域明显缩小；(4)计算了成形件的尺寸精度及切削率，并指出除模具形状的影响外，充填密度、橡胶模具老化、加载工艺等其他因素对总体切削率也有相当的影响。
