Processed products have refined structures and improved wear resistance.
Forging is the process of compressively forming metallic materials (carbon steel, stainless steel, alloy steel, non-ferrous metals) using molds by applying external forces that exceed the elastic limit, causing permanent deformation to achieve the desired shape and dimensions.
The processed products have a refined microstructure, which improves wear resistance.
The advantages include the continuity of metal fibers (fiber flow) and the increase in strength due to work hardening, which can enhance machinability in the case of soft materials, allowing for the use of cost-effective materials and sometimes omitting heat treatment.
The outstanding feature of this processing method is its high efficiency, producing several to hundreds of pieces per minute, allowing for processing from raw material to the final shape or a state close to it. Additionally, it offers high forming accuracy, reducing the need for further processing in subsequent steps.
Forging can be broadly categorized by temperature into three types: "hot forging," "cold forging," and "warm forging." Forging encompasses various deformation styles, including end-face correction, forward extrusion, backward extrusion, upset forging, hole punching (piercing), and blanking (trimming), among others.
