Description
- il est nécessaire d'équiper les fonderies d'un grand nombre de coquilleuses adaptées aux différents types de moule utilisés, du fait de la grande diversité de moules utilisés dans la production en petites et moyennes séries,
- les éléments constitutifs des coquilleuses, à savoir le bâti et les mécanismes d'actionnement mécaniques précités, sont généralement immobilisés définitivement du fait que leur démontage nécessiterait un travail manuel long et pénible, et que certains éléments ne peuvent être réutilisés, tels que les supports de vérins qui sont réalisés avec une longueur spécifique et adaptés à un moule donné,
- le coût de chaque coquilleuse ne peut être rentabilisé, du fait que la plupart des moules ne sont utilisés qu'une à six fois par an et à chaque fois pendant une durée généralement comprise entre une demi-journée et une semaine,
- chaque coquilleuse est souvent conservée pendant une très longue durée parfois supérieure à dix ans, ce qui engendre un besoin de stockage démesuré du fait de l'encombrement important de chaque bâti et de l'impossibilité de stockage en hauteur de ces derniers, et un coût de maintenance et d'approvisionnement en pièces de rechange très élevé,
- certains mouvements ne sont pas automatisés ou mécanisés, notamment lorsqu'il est nécessaire d'introduire des broches ou des noyaux suivant des directions inclinées par rapport à la verticale ou l'horizontale, ces opérations s'effectuant alors manuellement.
- le groupe de distribution hydraulique est souvent très nettement sous-utilisé du fait que la production de nombreuses pièces de fonderie ne nécessite généralement que le mouvement d'un ou de deux vérins de broches ou de noyaux, en plus des vérins de chapes,
- cette sous-utilisation ne permet pas d'amortir le coût très élevé des coquilleuses automatisées dans le cas d'une production en petites et moyennes séries,
- la durée de réglage d'un moule donné sur ces coquilleuses est très longue par rapport aux temps de production en petites et moyennes séries, ce qui rend leur utilisation incompatible avec des changements fréquents de moules, propres à la production en petites et moyennes séries,
- la diversité de formes des moules et de positions des broches ou noyaux dans la production en petites et moyennes séries, est telle que l'utilisation d'une unique coquilleuse automatisée n'est pas envisageable pour satisfaire tous les besoins.
