Mold failure is divided into abnormal failure and normal failure. Non-normal failure (early failure) refers to the mold has not reached a certain industrial level of recognized life on the service. Early failure in the form of plastic deformation, fracture, localized severe wear and tear. Normal failure refers to the use of the mold by mass production, due to slow plastic deformation or more uniform wear and tear or fatigue fracture and can not continue to serve.

Injection and guide sleeve units
There are two types of mold guiding methods and accessories for guide injection and guide sleeve unit types: (A). External guide type (mold base type or called the main guide), (B). Inner guide type (or auxiliary guide). In order to meet the requirements of precision molds, there is a high demand for the use of both the outer guide and inner guide types.
High life mold form and mechanism
