Abstract

método para produção de produtos de metal duro. a presente invenção está correlacionada a um método para moldagem por injeção ou extrusão de peças de metal duro ou cermet, usando um sistema aglutinante que compreende 20-70% de polímero ofefínico e 30-80% de cera. de acordo com a invenção, o dito polímero olefínico é um copolímero de polietileno e poli (alfa-olefina). ao utilizar um sistema aglutinante de acordo com a invenção, é obtido um comportamento de material mais rijo do corpo verde e uma temperatura mais baixa durante a moldagem por injeção ou extrusão.
