Finally, simulation software was developed with Visual C++ and Delphi for 2D molding analysis of MIM, which affords facilities for the quality forecast of 2D thin wall parts and optimal design of mold and process parameters. In the research of molding performance of MIM feedstock, for the shortcoming of capillary rheometry, it was propounded that using spiral mold test molding performance of feedstock, and a set of spiral mold was creatively designed with quickly exchange gates and closed mold cavity. With the spiral mold, an orthogonal experiment was made on getting regress equation of flow length L〓 of the heavy alloy feedstock. Then the rule of L〓 varying with Q〓, P〓, and ΔT〓 was discovered. Q〓 ranks first in the influence on process parameters of molding performance, P〓 and Δ T〓 second. Therefore the injection rate Q〓 should be controlled primarily to improve the flow performance of feedstock.

在MIM喂料注射成形性能研究方面，针对毛细管流变仪测试法衡量流动性能的不足，提出使用螺旋线模具测试喂料熔体的注射成形性能，创造性地设计了一套可快换浇口，模腔封闭的螺旋测试模，并在螺旋测试模上采用正交实验设计，得出了高密度重合金喂料流动长度L〓的回归公式，揭示了L〓随Q〓、P〓、△T〓和S〓的变化规律，并得出工艺参数对成形性能影响的强度顺序为Q〓最大，P〓与△T〓其次，因而改善喂料流动性能应优先控制注射速率Q〓。
