PCD wire drawing dies

Drawing Die After installation, you can normally produce qualified parts, a process called die in service. Under normal circumstances, we always want to be able to mold long enough period of service, in order to meet the actual needs of production.
but mold in the manufacturing process may have some defects, or the gradual emergence of some of the shortcomings in the service process, such as micro-cracks, slight wear, deformation, etc. In this case, although risks but mold We can continue to work, although this defect but did not lose the ability to serve the state is called mold damage.
damaged wire drawing dies for some reason, or the accumulation of mold damage to a certain extent, leading to mold damage, can not continue the service, called the failure of the mold. In production, the main working parts where the mold is damaged or can not continue to press the qualified workpiece, namely that the failure of the die. Failure is generally in the form of stamping dies plastic deformation, wear, breakage or cracking, metal fatigue and corrosion, and so on. Failure
drawing die sooner or later, according to the time of occurrence can be broadly divided into two categories: normal failure and early failure.
drawing die after a lot of production and use, natural wear and tear due to friction after or slow plastic deformation and fatigue cracks, the failure to achieve normal life is a normal phenomenon, normal failure. Mold does not meet the design using a predetermined period, both chipping, chipping, or breaking early damage; or because of severe local wear and plastic deformation can not continue to serve as an early failure. For the early failure of the mold, it must find its causes, efforts to take remedial measures.
