发明名称 Process for producing pieces of jewelry from precious metals and pieces of jewelry produced by it
摘要 Pieces of jewelry made from metal, particularly precious metal, are produced galvanoplastically, in that the precious metal is electrodeposited on an electrically conductive mould core having the spatial contour of the piece of jewelry and on reaching the desired coating thickness the mould core material is dissolved chemically or thermally from the jewelry body. In order to produce pieces of jewelry or parts thereof, which are exposed to mechanical stresses, the hollow jewelry body obtained is provided with a solid area made from the same metal in those parts of the jewelry item undergoing more pronounced mechanical stressing during further working or correct use. In this way, e.g. pendant eyes, connecting or joining members on bands, necklaces or the like, rings in the vicinity of the rim, brooches, supports, hooks, clasps or the like can be reinforced by a solid construction, so that at these points the piece of jewelry can either be subsequently worked or can absorb repeated stresses, such as tensile and bending stresses, wearing stresses or the like.
