Forging and pressing processes are two different materials forming technologies. Both processes have their own characteristics and can be used independently or in combination according to requirements.
Forging is a plastic deformation process of metal workpieces in the solid state. It can be divided into open die forging and closed die forging according to the tool type. It is mainly used to process and manufacture parts with complex shape and high dimensional accuracy. Commonly used deformation processes include upsetting, punching, trimming, piercing and machining. The objects produced are widely used in various fields, such as aerospace and automobile industries.
Press processing is a kind of material deformation forming technology by the action of pressing force. It is divided into cold pressing and hot pressing. Cold pressing is a forming process in which the material is rolled, punched and sheared under the action of external pressure. Hot pressing is a metal forming method in which metal products are formed at high temperature above the recrystallization temperature.
The most commonly used press processing equipment is the punch press. Compared with forging process, this process has the advantages of high production efficiency and less pressure loss. Therefore, press processing is widely used in making automobile fittings, metals and construction parts.
Forging and pressing processes are both effective means of metal workpiece forming. Different kinds of parts require different processing methods. According to the characteristics of materials, production efficiency, size accuracy and shaping complexity of parts, it will choose one of the two methods or combine them to carry out the manufacturing. Therefore, this process is of great significance for manufacturing industries.
