Main failure forms of wire drawing dies

Wire drawing die failure according to the occurrence of time, can be broadly divided into two categories: normal failure and early failure.

Normal failure: wire drawing die after a lot of production use, due to friction and natural wear or slow plastic deformation and fatigue cracks, after reaching the normal service life of the failure is a normal phenomenon, for normal failure.

Early failure: the mold does not reach the design of the use of the specified period, both collapse, cracking, fracture and other early damage; or because of serious local wear and plastic deformation and can not continue service, for early failure. For the early failure of the mold, must find the reasons for its generation, and strive to take remedial measures.
