Seus moldes desempenham pap\u00e9is fundamentais na produ\u00e7\u00e3o em massa nos setores automotivo e aeroespacial, bem como em eletr\u00f4nicos, bens de consumo e equipamentos m\u00e9dicos. Tanto a fundi\u00e7\u00e3o sob press\u00e3o quanto a moldagem por inje\u00e7\u00e3o de pl\u00e1stico podem produzir componentes altamente detalhados e intrincados com altas toler\u00e2ncias, mas ambas trabalham com princ\u00edpios, materiais e objetivos de aplica\u00e7\u00e3o final diferentes.<\/span><\/p>\n<p><span style=\"font-weight: 400;color: #000000\">Embora a simples tarefa de moldar o material em um molde pare\u00e7a semelhante, eles s\u00e3o externamente, em termos de material, condi\u00e7\u00f5es de processo, requisitos de projeto e aspectos de desempenho, totalmente diferentes.
