[0002] Track links are the connecting parts of tracks used in construction machinery such as excavators and bulldozers, and military machinery such as tanks. Hot die forging is a type of forging process technology. It generally refers to a precision forging method in which a metal blank is heated to a temperature higher than the recrystallization temperature of the material and then plastically formed into the shape and size of the forging using a die.
