What is forging today?
Forging is a technique that allows the creation of industrial parts with different shapes, materials and weights according to customer needs as explained by the forging company SBS Forge. In order to obtain a finished part, that is to say a raw piece of forging, there must be different handling temperatures and different forging processes depending on what the part will undergo later, such as calibration, painting or heat treatment.
What are the forging processes?
Among the processes that exist, there is circular rolling. With rolling, the metal undergoes deformation under the pressure of two cylinders. Passing between these two cylinders, the metal is crushed and it takes the form of parts that have been placed on the cylinders. SBS Forge uses this process to preform metals before they go into stamping. The forging business company SBS Forge talks about stamping when steel material takes the form of dies. This stamping is carried out hot, either by the effect of pressure or shock. We are talking about stamping for metal parts. For materials without iron such as copper or nickel, we speak rather of die-casting.
Sometimes, in order for the material to be properly distributed in the die, it must first undergo a rolling or drawing process with the stamping process.
When is free forge used?
According to SBS Forge, free forging is a process suited to the creation of small parts that do not require the use of many tools, or the production of small series of parts. In view of the limited quantities that are produced, free forging makes it possible to create pieces whose unit value is relatively low.
Free forging is one of the oldest processes that exists. SBS Forge uses it when it comes to creating hot workpieces and progressively deforming materials.
