Foreign patents have been analyzed and the main criteria have been developed for selection of the binder. The paper gives the examples of different types of binder materials, and demonstrates their advantages and disadvantages. The results have revealed the promising trend in the application of the binder for MIM process.MIM technologyinjection moldingmetal powdersbinderdispersantgranulated materialfeedstockmetal-polymer compositionpolymersthermoplasticspolyformaldehydeМИМ-технологиялитье под давлениемпорошки металлическиесвязующееповерхостно-активные вещества (ПАВ)гранулятфидстоккомпозиция металлополимернаяполимерытермопластыполиформальдегид[German R.M., Bose A.
