MIM deviation problem in technology

MIM technology has a shape change itself, but such change is predictable and usually is isotropic.And only commonly occur during sintering, so-called deformation is in the shape of irregular change, green of the binder concentration gradient in capillary force sufficient to cause warp, crack, and our goal is to minimize size deviation, and dimensional deviation depends on the size of the process in the process of control, this is one of the problems of MIM technology early, sintering conditions, conditions of geometric shapes and metal injection molding small changes will lead to big dimension deviation, sintering process due to the formation of sintering neck between powder particles, green strength.
