\nPour ce qui concerne certaines applications, il est souhaitable de sp\u00e9cifier les exigences en mati\u00e8re de finition de surface. Il s’agit de classifier la finition des surfaces brutes de coul\u00e9e des moulages en une s\u00e9rie de degr\u00e9s de fa\u00e7on \u00e0 ce que le type de finition requis puisse \u00eatre pr\u00e9cis\u00e9 \u00e0 l’avance. <\/strong><\/p>\n

  1. Imperfections de surface (couture de moule ferm\u00e9 \u00e0 froid, cloques, traces de coul\u00e9e d’huile, etc.) non prohibitives.<\/li>\n
  2. Certaines imperfections de surface (couture de moule ferm\u00e9 \u00e0 froid, patine, porosit\u00e9 de surface, etc.) non prohibitives.<\/li>\n
  3. Certaines imperfections de surface (couture de moule ferm\u00e9 \u00e0 froid, patine, porosit\u00e9 de surface, etc.) qui peuvent \u00eatre \u00e9limin\u00e9es par polissage des points concern\u00e9s, non prohibitives.<\/li>\n
  4. Imperfections de surface qui peuvent \u00eatre \u00e9limin\u00e9es par polissage automatique, non prohibitives.<\/li>\n
  5. Imperfections de surface non prohibitives qui seraient accentu\u00e9es par polissage \u00e9lectrochimique. Dans les cas o\u00c3\u00b9 l’ondulation (plan\u00e9it\u00e9) not\u00e9e par la r\u00e9flexion de la lumi\u00e8re peut constituer un motif de rejet, il est requis d’atteindre un accord sp\u00e9cial.<\/li>\n<\/ol>\n<\/div>\n

      \n
    1. Finition de surface non importante<\/li>\n
    2. Enduits protecteurs :
      \nAnodis\u00e9e (non d\u00e9corative)
      \nChromate
      \nPeinture industrielle
      \nFinition mate ou au vernis vermicul\u00e9<\/li>\n
    3. Enduits d\u00e9coratifs :
      \nLaques
      \n\u00e9maux
      \nPlacage (A1)
      \nFinition chimique
      \nFinition polie<\/li>\n
    4. Parties structurelles (zones de contraintes \u00e9lev\u00e9es)
      \nPlacage (Zn).
