Abstract

ELEMENTOS DE MOLDAR PARA PRODUÇÃO DE MICROESTRUTURAS. A presente invenção refere-se a um elemento de moldar, particularmente, molde de fundição para produção de microestruturas, particularmente, arranjos de microagulhas, que apresenta um corpo básico (10). Em um lado superior (12) do corpo básico (10) está prevista uma pluralidade de reentrâncias (14), que servem para recepção de material para produção da microestrutura. Para aperfeiçoar a qualidade da microestrutura a ser produzida, particularmente, durante um processo de secagem, estão previstos canais (18) no lado superior (12) do corpo básico (10), que, em cada caso, estão conectados com pelo menos uma das reentrâncias (14).
