Drawing (manufacturing)
Drawing is a metalworking process that uses tensile forces to stretch (elongate) metal, glass, or the metal is drawn (pulled), it stretches to become thinner, to achieve a desired shape and thickness. Drawing is classified into two types: sheet metal drawing and wire, bar, and tube drawing. Sheet metal drawing is defined as plastic deformation over a curved axis.

Jun 03, 2021 · What are the factors controlling the wire drawing process? In metal processing, using external force to let carbon steel, stainless steel, aluminum, copper and other metals forced through the drawing dies, the crosssection is compressed into the required shape and size, this is our common drawing process. Drawing process can be divided into ...
Wire Drawing Process | Contenti
The Process. Drawing wire through a drawplate changes its shape and reduces its diameter while simultaneously lengthening the wire. Drawing will also increase the temper, or hardness, of the wire. Each hole on a drawplate is marked with a number. This number does not belong to any system of measurement but is only for reference. StepByStep ...
Wire drawing
Wire drawing is a metalworking process used to reduce the crosssection of a wire by pulling the wire through a single, or series of, drawing die(s).There are many appliions for wire drawing, including electrical wiring, cables, tensionloaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.
