Knife Edge reduces 3.5mm to 1mm
Used mainly by jewellers and model ship builders to reduce the diameter of wooden dowels or wire by pulling them through successively smaller holes which shaves off a tiny bit of the diameter of the wire or wood with each pass. Specialist jewellers draw plates which change the shape of wire to squares, ovals or other shapes are also available.
Drawing Gold Wire. Another way of preparing gold or platinum for use in jewelry making is to draw the metal into wire. Precious metal wire is used to create prongs, filigree, and delicate designs. After pouring an ingot and rolling it into square rods on the rolling mill, you will form the metal into wire on a draw plate. The square rods of precious metal will be manually pulled through a series of tapered holes in a carbon steel plate. After each pass, the wire thins and has to be reheated and annealed to a cherry red to soften the metal so it can pass through the next gauge hole to further.
