Main failure modes of drawing die

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

Normal failure: After a large amount of production and use, the drawing die is naturally worn due to friction or slowly produces plastic deformation and fatigue cracks. Failure after reaching the normal service life is a normal phenomenon and is a normal failure.

Early failure: The mold has not reached the specified period of design and use, and it will cause early damage such as chipping, chipping, and breaking; or it can not continue to serve due to severe local wear and plastic deformation, which is an early failure. For molds that fail early, the cause must be found and remedial measures must be taken.
