| [1016] Electroforming for Innovative Design |
There are four principal methods of producing jewellery today: Hand making, using traditional craft skills, Investment (Lost wax) Casting, Pressing (stamping) and Electroforming.
More than 50 % of all jewellery is produced as hollow parts; this is mainly realized by using either a pressing technique or electroforming. The advantages of hollow jewellery are wearer comfort on the one hand, such as in the case of ear ornaments or brooches, and price on the other hand, since hollow parts are less expensive than solid parts due to precious metal savings.....

| [304] Evaluation of strength and quality of chains |
In recent years, we have witnessed a growing concern of manufacturers and retailers regarding the quality of the jewelry products. Closer attention is being paid to such issues as general aesthetic appearance, surface finish, color consistency, strength and overall durability of jewelry. Responding to the increasing quality requirements, we have made an attempt to develop some specific methods for testing the finished jewelry products including various chains, bangle bracelets, castings and components.....

| [444] Hollow Karat Gold Jewelry from Strip and Tube |
There is always pressure to reduce the cost of manufactured items and carat gold jewellery is no exception to this situation. In fact, it is only relatively recently (1997) that the economic and currency turmoil in countries like South Korea, Thailand, Malaysia and Indonesia had such an impact on the local gold price that, at times, gold jewellery sales effectively ceased altogether. In Indonesia, for example, at a time when the dollar gold price was falling, the gold price in the local currency increased by 90%. What, then, are some of the ways in which gold jewellery costs can be reduced? One approach is the use of mass production techniques to lower the unit manufacturing cost of items. Such techniques include the well-established chain making, stamping and investment casting, the more recent electroforming and the very recent powder metallurgy processes. These techniques are continually developing as equipment manufacturers make more advances and market their products more widely..... (2002)
