Techniques. 1.1, d) and closed die forging (Fig. The techniques of smithing may be roughly divided into forging (sometimes called "sculpting"), welding, heat treating, and finishing. Forging is different from machining in that material is not removed by these; rather the iron is hammered into shape. For forging of the largest forged pieces, e.g. Forging techniques are useful for working metal because they enable the desired shape to be given to the steel and also improve its structure, especially because they refine its grain size.

Traditional Japanese Forging Techniques . 560 14 It is designed for both experts and non-experts in the forging industry. 0000001776 00000 n Forging Forging is a basic process in which the work piece is shaped by compressive forces applied through various dies and tooling. The closed die process requires a significant amount of force. Cold forging encompasses many processes -- bending, cold drawing, cold heading, coining, extrusions and more, to yield a diverse range of part shapes. using conventional forging process techniques where dies are heated to 540 C (1000 F) or less. Forging techniques are useful for working metal because they enable the desired shape to be given to the steel and also improve its structure, especially because they refine its grain size.

Figure 2 illustrates the relative forgeability of ten aluminum alloys that constitute the majority of aluminum alloy forging production. Gyratory forging machine (GFM) is a precision forging process that produces cylindrical bar shapes by hot forging while the bar is rotating. Blacksmiths, mainly over the past 3000 years, have invented various techniques to work the material in different ways. This process gets the name “closed die” because the material is confined between an upper and lower die.
