No fabrico de moldes de precis\u00e3o, \u00e9 muito importante conseguir um paralelismo perfeito nos insertos do molde. Mesmo um pequeno desvio no paralelismo do inserto do molde pode levar a um desgaste desigual, flashing, qualidade inst\u00e1vel da pe\u00e7a e vida \u00fatil reduzida da ferramenta. Para ser justo, o paralelismo e a exatid\u00e3o dimensional s\u00e3o igualmente importantes.<\/p>\n\n\n\n
