Drawing (manufacturing)
metalworking process
Drawing is a manufacturing process for producing a wire, bar or tube by pulling on a material until it increases in length. This is typically accompanied by a thinning out of the material, usually through a reduction in the girth.
This technique has long been used to produce flexible metal wire by drawing the material through a series of holes of decreasing size. More recently drawing has been used with molten glass to produce high quality optical fibers.
