Normas de toler\u00e2ncia do molde de precis\u00e3o<\/figcaption><\/figure>\nNo mundo da moldagem por inje\u00e7\u00e3o, a diferen\u00e7a entre uma pe\u00e7a que encaixa perfeitamente e uma pe\u00e7a que falha na montagem resume-se a alguns microns. Estabelecer\u00a0normas de toler\u00e2ncia do molde de precis\u00e3o<\/strong>\u00a0n\u00e3o \u00e9 meramente um exerc\u00edcio t\u00e9cnico; \u00e9 uma necessidade contratual. Sem diretrizes de toler\u00e2ncia claras, os fabricantes n\u00e3o podem garantir que o seu componente de pl\u00e1stico se encaixe no lugar, vede corretamente ou rode suavemente.<\/p>\nEm\u00a0PartsMastery<\/strong>, vemos todos os dias as consequ\u00eancias de toler\u00e2ncias vagas.

Este guia explica as normas internacionais, os n\u00edveis de precis\u00e3o e como especificar toler\u00e2ncias que equilibram custo e fun\u00e7\u00e3o.<\/p>\nO que s\u00e3o normas de toler\u00e2ncia de moldes de precis\u00e3o?<\/h3>\n
Antes de nos debru\u00e7armos sobre n\u00fameros espec\u00edficos, temos de definir o termo.\u00a0Normas de toler\u00e2ncia do molde de precis\u00e3o<\/strong>\u00a0referem-se ao desvio aceit\u00e1vel entre o modelo CAD (a geometria nominal) e a cavidade f\u00edsica real em a\u00e7o, bem como a pe\u00e7a pl\u00e1stica resultante.<\/p>\nEstas normas abrangem tr\u00eas dom\u00ednios distintos:<\/p>\n

Diferentes mercados seguem diferentes\u00a0normas de toler\u00e2ncia do molde de precis\u00e3o<\/strong>. Compreender qual a norma que o seu cliente espera \u00e9 fundamental para o com\u00e9rcio internacional.<\/p>\nISO 286 (Norma Internacional)<\/h4>\n
Este \u00e9 o sistema de toler\u00e2ncias mais amplamente reconhecido. Utiliza uma combina\u00e7\u00e3o de uma letra (toler\u00e2ncia do furo) e um n\u00famero (grau). Para moldes de inje\u00e7\u00e3o, os graus relevantes s\u00e3o:<\/p>\n

A engenharia alem\u00e3 exige regras mais rigorosas. A norma DIN 16749 aborda especificamente as toler\u00e2ncias de moldagem por inje\u00e7\u00e3o em tr\u00eas grupos:<\/p>\n
\n- \n
Grupo 1 (Fina):<\/strong>\u00a0Para pe\u00e7as t\u00e9cnicas de alta precis\u00e3o (lentes \u00f3pticas, caixas de bombas).<\/p>\n<\/li>\n- \n
Grupo 2 (M\u00e9dio):<\/strong>\u00a0Para pe\u00e7as t\u00e9cnicas normalizadas (conectores, interruptores).<\/p>\n<\/li>\n- \n

Mesmo com um molde perfeitamente usinado, uma engrenagem de POM pode variar em \u00b10,05mm simplesmente devido \u00e0s taxas de cristaliza\u00e7\u00e3o.
