Em\u00a0PartsMastery<\/strong>, A nossa empresa concebe e fabrica produtos de elevado desempenho\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0ferramentas que proporcionam milhares a milh\u00f5es de disparos com uma estabilidade dimensional rigorosa.<\/p>\n

Este guia completo explica o que \u00e9 um\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0\u00e9, como difere dos moldes de pl\u00e1stico, os princ\u00edpios cr\u00edticos de conce\u00e7\u00e3o e como selecionar o tipo de a\u00e7o adequado para a sua aplica\u00e7\u00e3o.<\/p>\n

1. O que \u00e9 um molde de fundi\u00e7\u00e3o injectada?<\/h3>\n

A\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0(frequentemente designada por matriz) \u00e9 uma ferramenta de duas partes feita de a\u00e7o especializado para ferramentas de trabalho a quente. A\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0consiste numa metade de cobertura fixa (estacion\u00e1ria) e uma metade de ejetor (m\u00f3vel). O metal fundido \u00e9 injetado a alta velocidade (30-100 m\/s) e a alta press\u00e3o (1.500-10.000 PSI) na\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0cavidade. O metal solidifica-se em milissegundos ou segundos, e a\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0abre-se para ejetar a pe\u00e7a met\u00e1lica acabada.<\/p>\n

Ao contr\u00e1rio dos moldes de pl\u00e1stico que fazem ciclos a 20-200\u00b0C, um\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0funciona a uma temperatura de superf\u00edcie de 150-350\u00b0C com metal fundido a 620-680\u00b0C (alum\u00ednio) ou 380-420\u00b0C (zinco). O choque t\u00e9rmico \u00e9 o principal inimigo de qualquer\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>. Uma conce\u00e7\u00e3o deficiente ou uma manuten\u00e7\u00e3o incorrecta\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0desenvolver\u00e1 um controlo t\u00e9rmico - uma rede de fendas finas na superf\u00edcie que se transferem para todas as pe\u00e7as fundidas.<\/p>\n

O\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0O a\u00e7o deve resistir \u00e0 fadiga t\u00e9rmica, \u00e0 eros\u00e3o e ao controlo t\u00e9rmico:<\/p>\n

A\u00e7o para ferramentas H-13 (46-50 HRC):<\/strong>
\nA norma do sector\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0material para alum\u00ednio e magn\u00e9sio. O H-13 oferece uma excelente resist\u00eancia ao controlo t\u00e9rmico e \u00e0 fadiga t\u00e9rmica. Um H-13 corretamente tratado termicamente\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0pode produzir 50.000-150.000 disparos antes de necessitar de ser renovado.<\/p>\n

A\u00e7o para ferramentas H-11 (46-50 HRC):<\/strong>
\nSemelhante ao H-13 mas com uma tenacidade ligeiramente superior. H-11\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0s\u00e3o preferidas para pe\u00e7as de zinco e pequenas pe\u00e7as de alum\u00ednio onde a resist\u00eancia ao impacto \u00e9 cr\u00edtica.<\/p>\n

DIEVAR (Uddeholm):<\/strong>
\nUm pr\u00e9mio\u00a0molde de fundi\u00e7\u00e3o injectada<\/strong>\u00a0a\u00e7o com maior resist\u00eancia \u00e0 fadiga t\u00e9rmica.
