Forging presses
Introduction
forging is a manufacturing process that involves shaping metal.
Like lamination and extrusion, it is a process of manufacturing objects formed by plastic deformation "Plasticity (solid mechanics)") in which the deformation of the material is produced by the application of compression forces.
This process is used to give a certain shape and properties to the metals and alloys to which it is applied using high pressures. Deformation can be carried out in two different ways: by pressure, continuously using presses, or by impact, intermittently using pile hammers.
It should be noted that it is a metal forming process in which no chips are removed, resulting in significant material savings compared to other processes, such as machining.

Los principales tipos de forja que existen son:.
1. Free forging
It is the oldest type of industrial forging. This is characterized because the deformation of the metal is not limited (it is free) by its shape or mass.
It is used to manufacture single pieces or small batches of pieces, where these are normally large in size. Additionally, this type of forging serves as preparation of the preforms to be used in die forgings.
It can also be found as an open die forge.
2. Drop forging
This type of forging consists of placing the piece between two dies that, when closed, form a cavity with the shape and dimensions that are desired for the piece. As the process progresses, whether using hammers or presses, the material is deformed and adapted to the matrices until it acquires the desired geometry. This process must be carried out with a burr bead that serves to provide the necessary pressure when filling the final areas of the piece, especially if the radius of agreement of the piece is small and may be without burr, depending on whether the dies incorporate a relief area to accommodate the excess material (burr) or not. It is used to manufacture large series of parts whose dimensions and geometries can vary widely. The dimensions of these pieces range from a few millimeters in length and grams in weight to several meters and tons, and their geometries can be simple or complex.
