In addition to the 2- and 4-column articulated presses, there are other variants of articulated presses that are used in various applications. One of the variants is the so-called articulated arm joint press. In this type of press, the ram is driven by an articulated arm mechanism that moves the ram in a more linear motion. Articulating-arm presses are particularly suitable for applications where high forces are required but linear motion is needed. Another type of articulated presses are the so-called C-frame articulated presses. In these presses, the ram is moved through a curved frame that gives it greater freedom of movement. C-frame articulated presses are ideal for applications where large workpieces need to be processed. Finally, there are what are known as double toggle articulated presses. This type of press has two toggle mechanisms that drive the ram and give it a more precise and stable motion. Double toggle joint presses are ideal for applications where high precision and repeatability are required.
