Shor Lok-Blok Metal Mold Making System: makes metal molds that are the same dimensions as standard rubber molds. The process is simple (though somewhat time consuming) and requires no skills.
|
||||||||||||||||||||||||||||||||||||
The following items are required to make
metal molds. The heart of the system (other than the instructions, is the
Lok-Blok Mold Frame. This frame can also be used for making excellent rubber molds with no
packing. Please note that you may already have many of these items or may wish to purchase
some of them (like the lacquer and remover) locally:

| Shor Electroformer | |
| Electroforming is a plating process that requires a very special kind of plating machine; an electroformer. All plating machines, electroformers included, work on the same general principle, they use DC current to cause microscopic plates of metal to adhere to, and build up on, the surface of the piece being plated. The low amperage and highly filtered current of electroformers produce small, evenly distributed plates that adhere much better to each other and the underlying substrate than with standard plating rectifiers. With a standard plating process, the thickness of the plating is relatively thin ( a few microns at most) and strong adhesion and even distribution is not critical. With electroforming, however, the plating is hundreds or thousands of times thicker. If a standard rectifier were used to produce such a thick coating, the coating would not only look very uneven, simply rubbing it would cause the plating to peel off the model. A magnetic stirrer is generally used in conjunction with an electroformer to insure a very smooth, even coating. Click hyperlink for electroforming videos. Electroforming is used to do two very different things: to build up models to compensate for shrinkage or to make hollow jewelry from wax models by building up a heavy metal coating on a wax model. When copying models, it is necessary to compensate for the inevitable shrinkage that occurs in the various stages of the casting process. Electroforming is the only known method of doing this. To make hollow jewelry, the wax is painted with a metallic electrically conductive paint (usually silver paint) and the electroformer creates a metal coating on top of the wax. The wax is then heated and drained, leaving a hollow core. For information on water soluble wax, see Shor Water Soluble Waxes. For an article on the electroforming process see Forming a Niche. | |
