The Concept of Forging

Casting is the process of melting metal into a liquid that meets certain requirements and pouring it into a cast, which is cooled and solidified and cleaned up to obtain castings with predetermined shape, size and performance.


Forging is a process method that hydraulic cylinder manufacturers use forging machinery to exert pressure on metal blanks, so that they produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can be divided into: (1) open forging (free forging) by forming method. The use of impact or pressure to deform the metal between the upper and lower two iron (blocks) to obtain the required forgings, mainly hand forging and mechanical forging. (2) Closed mode forging.


Metal blanks in a certain shape of the forging mold in the mold edgy deformation and obtain forgings, can be divided into die forging, cold, rotary forging, extrusion and so on.


Forging according to deformation temperature can be divided into hot forging (processing temperature is higher than the recrystallization temperature of the blank metal), temperature forging (lower than the recrystallization temperature) and cold forging (room temperature).
