Forging is a general term of calcination and stamping die. It is a forming processing method that uses the drill, anvil block, punching needle or pressure the blank according to the mold shell of 200 tons of high-speed punch forging machinery equipment to cause plastic deformation, and then obtains the desired appearance and specifications of the parts. During the calcination process, the blank generally produces significant plastic deformation and has a lot of plastic deformation fluidity. In the stamping die processing, the blank key according to the change of the total area of each position of the interior space parts and formed, its internal does not appear a large distance of plastic deformation liquidity. The forging key is used for processing metal material parts, and can also be used for processing some non-metal materials, such as rubber products, vulcanized rubber, porcelain billet, billet body and the forming of polymer materials, etc. Forging and steel industry in cold rolling, drawing and so on belong to plastic deformation processing, processing or work pressure, but the hardware key used in the production of high-speed punch press forging manufacturing metal parts, and the key to cold rolling, drawing, etc used in the production of manufacturing board only, amorphous strip, pipe fittings, practical metal composite materials such as aluminum and cable. Forging is the general term of calcination and stamping die, as industrial production and trade, also known as material trade. Stamping die processing is a production process of commodity parts with a certain appearance, specifications and characteristics by virtue of the driving force of basic or special stamping machine tools, so that the plate is immediately subjected to deformation force and carry out deformation in the mold.
