Abstract

PURPOSE:To intend the thinning a clockface by forming the clockface with an alumite treatment after injecting melting aluminium powders on a given metal surface. CONSTITUTION:After preparing a letter plate 1 with a brass and setting legs 2 thereto, an aluminium alloy film 3 having 10-50mu in thickness is formed by injecting melting Al or Al alloy powders thereon. Then, when the letter plate is completed by alumite treatment, the thickness of the letter plate can be made thinner than that of when the Al plate is used.
