dicas para lan\u00e7adores<\/a>, etc.<\/p>\nDiferen\u00e7a entre alum\u00ednio usinado e alum\u00ednio fundido sob press\u00e3o<\/h2>\n
A liga de alum\u00ednio apresenta boa dissipa\u00e7\u00e3o de calor e boa apar\u00eancia, por isso \u00e9 amplamente utilizada. Qual \u00e9 a diferen\u00e7a entre o alum\u00ednio usinado e o processo de fundi\u00e7\u00e3o sob press\u00e3o de alum\u00ednio? A diferen\u00e7a entre o alum\u00ednio usinado e o alum\u00ednio fundido sob press\u00e3o reside principalmente nos seguintes seis aspectos:<\/p>\n
1. Diferen\u00e7as no material<\/h3>\n
O material utilizado na fundi\u00e7\u00e3o sob press\u00e3o de ligas de alum\u00ednio geralmente \u00e9 o ADC12 ou o ALsi9cu3, enquanto o alum\u00ednio automotivo geralmente \u00e9 o 6063 ou o 6061.<\/p>\n
2. Diferen\u00e7a na apar\u00eancia<\/h3>\n
O alum\u00ednio fundido sob press\u00e3o \u00e9 equivalente ao processo de moldagem por inje\u00e7\u00e3o de pl\u00e1stico e pode ser fabricado em qualquer formato. A carca\u00e7a externa do poste de ilumina\u00e7\u00e3o p\u00fablica \u00e9 geralmente feita de alum\u00ednio fundido sob press\u00e3o. O alum\u00ednio utilizado em autom\u00f3veis apresenta se\u00e7\u00e3o transversal uniforme, com poucas varia\u00e7\u00f5es, como no dissipador de calor da l\u00e2mpada incandescente e no perfil de alum\u00ednio das portas e janelas.<\/p>\n
3. Diferen\u00e7a na condutividade t\u00e9rmica<\/h3>\n
A condutividade t\u00e9rmica do alum\u00ednio automotivo \u00e9 de cerca de 180-190 W\/m\u00b7K, enquanto a condutividade geral do alum\u00ednio fundido sob press\u00e3o \u00e9 de cerca de 80-90 W\/m\u00b7K.<\/p>\n
4. Diferen\u00e7a de custo<\/h3>\n
O custo das pe\u00e7as fundidas sob press\u00e3o e do alum\u00ednio usinado varia, e \u00e9 calculado com base no peso e na usinagem. Calcule os custos com base nos pre\u00e7os dos materiais e na m\u00e3o de obra em tempo real. Relativamente falando, o custo da fundi\u00e7\u00e3o sob press\u00e3o de alum\u00ednio \u00e9 mais alto, mas \u00e9 preciso analisar a situa\u00e7\u00e3o espec\u00edfica.<\/p>\n
5. Diferen\u00e7a na efici\u00eancia da produ\u00e7\u00e3o<\/h3>\n
A efici\u00eancia de produ\u00e7\u00e3o da moldagem por inje\u00e7\u00e3o \u00e9, sem d\u00favida, maior. Na produ\u00e7\u00e3o em lote, geralmente s\u00e3o produzidas mais de 1.000 pe\u00e7as por dia, com dimens\u00f5es est\u00e1veis e uma taxa de encolhimento de 0,5%. H\u00e1 mais componentes processados em alum\u00ednio usinado. Como o pr\u00f3prio nome indica, trata-se de alum\u00ednio torneado, e a efici\u00eancia \u00e9 naturalmente menor.<\/p>\n
6. Diferen\u00e7a na aplica\u00e7\u00e3o<\/h3>\n
A fundi\u00e7\u00e3o de alum\u00ednio \u00e9 amplamente utilizada em autom\u00f3veis, postes de ilumina\u00e7\u00e3o p\u00fablica e na ind\u00fastria de telefonia celular. O alum\u00ednio usinado \u00e9 amplamente utilizado em lumin\u00e1rias embutidas, lumin\u00e1rias de teto, portas e janelas.<\/p>","protected":false},"excerpt":{"rendered":"
