  2. Extrusion - Wikipedia

    en.wikipedia.org/wiki/Extrusion

    Hot extrusion is a hot working process, which means it is done above the material's recrystallization temperature to keep the material from work hardening and to make it easier to push the material through the die. Most hot extrusions are done on horizontal hydraulic presses that range from 230 to 11,000 metric tons (250 to 12,130 short tons ...

    en.wikipedia.org/wiki/Metal_fabrication

    A set of six-axis welding robots. Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [1] process involving the creation of machines, parts, and structures from various raw materials.

    Delta robots [5] are also referred to as parallel link robots. [6] They consist of parallel links connected to a common base. Delta robots are particularly useful for direct control tasks and high maneuvering operations (such as quick pick-and-place tasks). Delta robots take advantage of four bar or parallelogram linkage systems.

  5. Rule based analysis of extrusion process - Wikipedia

    en.wikipedia.org/wiki/Rule_based_analysis_of...

    During an extrusion process it is essential to consider the surface finish of exposed product surfaces. As a general rule, the narrower an exposed surface, the more uniform its finish becomes. Webs, flanges and abrupt changes in metal thickness may show up as marks on the opposite surface of an extrusion, particularly on thin sections. The ...

    en.wikipedia.org/wiki/Microextrusion

    Microextrusion is an outgrowth of microforming, a science that was in its infancy in the early 1990s. In 2002, Engel et al. expressed that up to that point, only a few research experiments involving micro-deep drawing and extruding processes had been attempted, citing limitations in shearing on billets and difficulties in tool manufacturing and handling.

  7. Equal channel angular extrusion - Wikipedia

    en.wikipedia.org/.../Equal_channel_angular_extrusion

    Equal channel angular extrusion (ECAE) called also equal channel angular pressing (ECAP) is one technique from the Severe Plastic Deformation (SPD) group, aimed at producing Ultra Fine Grained (UFG) material. [1] The method was developed in the Soviet Union in 1973 by Segal. However, the dates are not always consistent. [2]
