cold forging

Hot forging, the deformation energy and deformation resistance are very small, forging complex shapes of large forgings. To obtain high dimensional accuracy of the forgings, in the 900-1000 temperature domain with hot forging processing. In addition, pay attention to improve the working environment for hot forging. Forging die life (hot forging 2-5 thousand, warm wrought 1-2 million, cold forging 2-5 million) compared with other temperature forging is shorter, but it's a large degree of freedom, low cost .
