Abstract
PURPOSE:To save material and improve workability by a method wherein, after material has been extruded to form a watch case and made hollow by means of cold forging, the material is cut in such a way that it has the thickness suitable for one piece of a watch and made into a watch case. CONSTITUTION:Aluminum allloy is extruded and formed in conformity with the external shape of a watch case and the formed material is made hollow by means of cold forging. The hollowly formed material 2 is cut in such a way that it has the thickness suitable for one piece of watch and made into a basic material 3 to be reduced to a watch case. The hollow material cut into the basic material for making a watch case is forged to regulate its composition and increase its hardness, before being processed by cutting and provided with surface processing to form a watch case.
