With the electroforming technique, the jeweler can easily design and produce any shape, form and size. In other words, the use of electroforming eliminates the limitations of jewelry shaping. With this method, large jewelry can be made easily. It is also possible to produce many ornaments and jewelry in a hollow form. For this reason, the jewelry that is made with this method is often light in weight and is very reasonable in terms of cost.
On the other hand, it is very easy for consumers to wear and carry jewelry that is produced with the electroforming technique; At the same time, they also have an eye-catching beauty.
In fact, the electroforming method has created a significant relationship between the weight and size of jewelry. The large size of jewelry with very low weight and as a result the reasonable price has attracted the attention of many consumers. In addition, the jewelry made by electroforming method has more shine and polish.
🔶 Electroforming process steps in jewelry making 🔶
Electroforming process is performed on wax that is produced from petroleum derivatives. At first, the wax is melted and takes the desired shape during the casting process in a metal or non-metal mold with minerals. Next, a number of thin copper wires are connected to the cast wax. To create an electric current, the wax piece is coated with silver colors. Next, the wax piece is plated in a tub of copper sulfate using a thin layer of copper for about 15 minutes. This prevents the silver layer from dissolving on the wax surface in the low amp cyanide bath.
After the above steps, the wax piece is washed. Then it is electroformed in the main tub, which is silver cyanide. The main ampere one is between 1614 and 1076 square meters. In this process, both the bath has a high concentration and the current density is higher than the amount of amperes in normal electroplating.
Furthermore, reverse current or periodic current can be used to create a surface without knots and completely smooth. This stream has about 60 seconds going and 10 seconds returning. Of course, according to the type of structure required and the characteristics of the electroforming layer, the flow speed can be changed. In order to have a suitable structure, the necessary turbulence is created in the tub by moving the cathode rod or the filter pump.
After 60 minutes, the piece will find the necessary strength and the thickness of the silver will reach the desired size. In this case, they remove the piece from the tub, then make holes in it in a suitable place that is not visible. By immersing the piece in boiling water, the wax melts and comes out of the hole. After this step, the piece of jewelry that has reached the desired shape is put into the silver cyanide tub and left inside the tub for two hours. As long as the piece does not bend and reaches the required thickness and strength. The thickness of the plated layer is usually about 5 mm. Of course, the amount of thickness depends on various factors such as the type, shape and form, complexity and details of the part and the desired strength of the electroforming layer. For example, jewelry made for a bracelet is stronger than a necklace.
🔶🔶 The most important advantages of the electroforming method 🔶🔶
🔸 One of the most important advantages of the electroforming method is the possibility of creating light jewelry at a reasonable price.
Saving gold consumption due to the hollowness of the jewelry produced by electroforming is another advantage of this method.
🔸 Electroforming is considered one of the latest jewelry making technologies in the world. This method has many advantages over pressing; Because it is possible to produce and create complex designs with many details in electroforming. In addition, there is no need for many tools and machines to perform this method.
🔸 The use of electroforming for the production of jewelry and all kinds of decorative sculptures is widely used. With this method, you can make all kinds of earrings, brooches, chains, pendants and bangles in different designs.
