Extrusion History

3476-1

 Process in which a metal bar under pressure from the mold with the specific form of data transmission and reduce the cross-sectional area, extrusion, extrusion Namnd.fraynd compared with other methods of shaping method is relatively new. Extrusion was first introduced in the early nineteenth century and the first lead pipes were produced in this way. The late nineteenth century, about the year 1894, with the construction of a high-power presses achieve at a very high compressive forces was made ​​possible through the production tubing and brass.
If the initial billet is heated before forming, hot extrusion Otherwise, Namnd.fraynd Cold hot extrusion to produce semi-finished steel products with relatively long and constant cross-section (such as the profiles .In of the hollow, symmetrical and asymmetrical steel, aluminum and copper alloys) and cold extrusion, cold deformation due to high deformation resistance, for producing steel ingots rather a process in which a mold with the specific form is passed under pressure from and reduce its surface area, compared with other methods of extrusion, extrusion Namnd.fraynd shaping method is relatively new. Extrusion was first introduced in the early nineteenth century and the first lead pipes were produced in this way. The late nineteenth century, about the year 1894, with the construction of a high-power presses achieve at a very high compressive forces was made ​​possible through the production tubing and brass.
