How are these earrings made? Electroforming is a highly specialized process of metal part fabrication using electrodeposition in a plating bath over a base form or mandrel which is subsequently removed. Technically, it is a process of synthesizing a metal object by controlling the electrodeposition of metal passing through an electrolytic solution onto a metal or metallized form”(http://www.katefowle.com/tips.htm). More simply, a metal skin is built up on a metal surface, or any surface that has been rendered electroconductive through the application of a paint that contains metal particles. Essentially, a metal part is fabricated from the plating itself. This differs from electroplating basically because the skin is much thicker and can exist as a self-supporting structure if the original matrix is removed. The object being electroformed can be a permanent part of the end product or can be temporary (as in the case of wax), and removed later, leaving only the metal form, the “electroform”. The advantage of the electroforming process is that it reproduces the form or mandrel to within one micrometre without the shrinkage and distortion associated with other metal forming techniques such as casting, stamping or drawing. And, since the mandrel is machined as an outside surface, close dimensional tolerances and high surface finishes can be held and maintained on complex interior configurations..... |
