Injection molding feed of Fe-Ni-Cu-C alloy coarse powder with particle size of 60um was prepared, effect of rate of shear, temperature and proportion of powder and binder to rheological behavior of feed was studied, viscosity number of three kinds of feed in different temperature was measured by capillary viscosimeter strain sensitivity factor three kinds of feed with different component were compared.

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.
