Anyang forging hammer is a free forging hammer. Using a self-contained power hammer eliminates the need for an external air supply or high pressure hose. It can be used for various free forgings, such as drawing, upsetting, stamping, hot shearing, forging welding, bending and torsion. It can be used for die forging with pressurized die, but cannot be used for closed die forging, because the impact energy of closed die forging is very large, and the main components such as hammer rod, guide rail, working cylinder, etc. will be damaged.
