Drawing (manufacturing) Diagram of bar drawing; the workpiece is pulled from left (tension) rather than pushed from the right (compression). Drawing is a manufacturing process that uses tensile forces to elongate metal, glass, or plastic. As the material is drawn (pulled), it stretches and becomes thinner, achieving a desired shape and thickness.
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [ 1 ]: p.375 The same or similar terms are used in glassmaking for the ...
Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through one or more dies. There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.
Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or inconsequential, depending on the application.
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate ...
Extrusion. Extruded aluminium with several hollow cavities; T slots allow bars to be joined with special connectors. Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create ...
Rigid copper is a popular choice for water lines. Rigid or "Hard" copper tubing is generally referred to as "pipe". Copper "piping" is referred to by nominal pipe size, or the inner diameter. It is joined using a solder/sweat, roll grooved, compression, or crimped/pressed connection. Rigid copper, rigid due to the work hardening of the drawing ...
Swaging. Swaging (/ ˈsweɪdʒɪŋ /) is a forging process in which the dimensions of an item are altered using dies into which the item is forced. [1] Swaging is usually a cold working process, but also may be hot worked. [2] The term swage may apply to the process (verb) or to a die or tool (noun) used in that process.
