Forging is the process of compressively forming metallic materials (carbon steel, stainless steel, alloy steel, non-ferrous metals) using molds, applying external forces that exceed the elastic limit to create permanent deformation and achieve the desired shape and dimensions. The processed products have a refined microstructure, resulting in improved 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, potentially allowing for the use of less expensive materials and the omission of heat treatment. The notable aspect of this processing method is its high efficiency, capable of producing several to hundreds of pieces per minute, allowing for the material to be shaped into its final form or a state close to it. Additionally, it offers high forming precision, 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. *For more details, please download the PDF or contact us.*
