What caused the failure of the AC plug mold?

       For many manufacturers that produce ac plugs! The quality of an ac plug mold plays a crucial role, and the quality of the plug mold purchased by many manufacturers is very reliable, but the gap between the usage life and the guess of practice is too large, so what causes the ac plug mold How to use life shortening?

　　 The failure of the AC plug mold is divided into abnormal failure and normal failure. Abnormal failure (pre-failure) means that the AC plug mold can not be put into service without reaching the recognized life under a certain industrial level. The early failure modes include plastic deformation, fracture, and severe wear. Normal failure means that AC plug molds are produced and used in large quantities, and they cannot continue to serve because of slow plastic deformation or relatively uniform wear or fatigue fracture. This is why the service life of ac plug molds will be shortened. AC plug mould

  The normal AC plug mold service life before the normal failure, the number of qualified products produced is called AC plug mold normal life, referred to as AC plug mold life, the AC plug mold is produced before the first modification of the qualified product The number is called the first life; the number of qualified products produced after the AC plug mold is revised once before the next revision is called the repair life. The life of the AC plug die is the sum of the initial life and the corrected life.

　　The life of the AC plug mold is related to the shape and structure of the AC plug mold. It is the data function of the AC plug mold and the design and manufacturing level of the AC plug mold during the required period. Comprehensive reflection of the heat treatment level of the AC plug mold and the level of operation and maintenance. The life of AC plug molds reflects the level of metallurgical industry and machinery manufacturing industry in a region and a country to a certain extent, but I believe that these problems will be dealt with one by one in the near future.
