Abstract

Cette invention se rapporte à un boîtier de batterie de haute qualité, ayant une excellente formabilité en continu, et à une tôle d'acier traitée en surface utilisée pour produire ce boîtier de batterie. On obtient ce boîtier de batterie en formant, sur les surfaces interne et externe d'une ébauche de tôle constituant la tôle d'acier, des tôles d'acier traitées en surface ayant chacune une couche plaquée de nickel à finition terne, par un procédé de formage DI ou DTR. En raison de son effritement considérablement réduit, la couche plaquée de nickel à finition terne nécessite une charge de poinçonnage inférieure dans le processus de coiffage et permet de réduire au minimum les défauts causés par le contact avec le métal de l'outil de découpage à matrice et poinçon, afin d'augmenter la durée de vie de la matrice en métal et accroître la productivité en continu d'un tel boîtier de batterie.
