The dimensions and mechanical properties of MIM products are influenced by the feedstock characteristics, the process parameters of the injection moulding, as well as the debinding and the sintering. Numerical simulations are a very important feature of the beginning of any product or technology development. In the article two different techniques for measuring the rheological properties of MIM feedstocks are presented and compared. It was established that capillary rheometers are more appropriate for MIM feed stocks, while on the other hand, parallel-plate rheometers are only suitable for shear rates lower than 10 ssup{-1}. Later on we used genetic algorithms to determine the model coefficients for some numerical simulation software. The results of the simulation of the filling phase and a comparison with the experimental results are presented in the article</dc:description><dc:description xml:lang="sl">Brizganje kovinskih prašnatih materialov (MIM) je uveljavljena tehnologija, primerna za izdelavo majhnih, kompleksnih izdelkov visoke natančnosti. Dimenzije in mehanske lastnosti MIM-izdelkov so odvisne od lastnosti mešanic, procesnih parametrov brizganja, odstranjevanja veziva in sintranja. Numerične simulacije so pri razvoju novih izdelkov oziroma tehnologij zelo pomembne. V prispevku je narejena primerjava in predstavitev dveh metod za merjenje reoloških lastnosti MIM mešanic. Ugotovljeno je bilo, da je kapilarni reometer primernejši za meritve pri višjih strižnih hitrostih, medtem ko je reometer z vzporedno ploščo primeren le za strižne hitrosti do 10 sna{-1}. V nadaljevanju je bila uporabljena metoda genetskih algoritmov za določitev koeficientov matematičnega modela, ki se uporablja v programski opremi za numerične simulacije brizganja. Na koncu so predstavljeni rezultati simulacije polnjenja orodne votline, narejena pa je tudi primerjava z eksperimentalnimi rezultati</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-JWHBJRB1"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-JWHBJRB1" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-JWHBJRB1/e3932638-fa76-4354-8967-a408217a5b5e/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-JWHBJRB1/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-JWHBJRB1" /></ore:Aggregation></rdf:RDF>
