Dry wire drawing is a process of metalworking in which metal is pulled through a die to reduce its cross section and make it longer. It is also known as wire drawing and it is used in many industrial applications such as the manufacture of wires and cables, as well as in jewelry making.

The process begins by winding a coil of wire onto a spool and placing it in a die, which is essentially a hollow tube or an enclosed space with a specific interior shape. The wire is then clamped to the spool and drawn through the die by a pulling mechanism such as a motor, pulley or hand-crank. As the wire passes through the die, it is pulled along and the metal is reduced in size and length.

The most common type of dry wire drawing is known as cold drawing. This is done by pulling the wire through the die at room temperature. This process does not involve heat so it is often used for heat-sensitive materials like stainless steel. Cold drawn wires are often used for making jewelry components such as jump rings and ear wires.

Another type of dry wire drawing is hot drawing, which is done at temperatures higher than room temperature. Hot drawing is more commonly used for softer metals like aluminum and copper. The heat softens the metal and allows it to be pulled through the die more easily. Hot-drawn wires are often used for manufacturing electrical components and industrial supplies.

No matter which type of wire drawing you use, the process helps to improve the properties of the material by providing greater strength, uniformity, and aesthetically pleasing shapes. By tailoring the die shape and size, wire drawing can also be used to create a variety of custom wire products.
