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.
