Abstract

PURPOSE: To manufacture a pointer which is light, and high in its appearance and quality, abundant in a design conception, by executing low temperature-annealing to an aluminum pointer body at a specific temperature preceding to embossing, and driving a skirt-collar into the lower surface of the pointer seat part in the embossing process.
CONSTITUTION: An aluminum pointer body 1 is subjected to external pattern-drawing by a continuous press, and subsequently, a brass collar 2 provided with a hole part for fixing it to a movement pointer shaft is fitted into the pointer body 1, and is fixed by caulking. Subsequently, low temperature-annealing is performed at a temperature of 160°CW200°C for 20minW60min in order to recover elongation without dropping hardness of the pointer body 1. Subsequently, a seat part 6 of the pointer body 1 is formed by the pressing process, and a curved surface is formed on the pointer body 1. A collar- skirt 4 is driven into the lower surface of the pointer seat part 6 so that a sufficient working amount can be obtained on the upper surface of the pointer seat part 6 to which diamond-cut working is performed. Subsequently, the diamon-cut working is performed to a projecting part 7, it is finished beautifully, spattering treatment is performed after washing, and it is finished to a gold color by covering it with an Au film, by which a finished-product is obtained.
