How Long is the Service Life of Injection Molding Mold?

The service life of an injection mold is measured by its expected production cycles, that is, the times the mold is used to manufacture a part. Therefore, in essence, a production cycle is directly related to the number of parts that an injection mold can produce in its life cycle.


Ⅰ. How is the lifespan of injection molding mold measured?

SPI (Society of the Plastics Industry) classifies injection molds according to their expected life.

Class 101 - life expectancy is + 1,000,000 times. These are the most expensive injection molds.

Class 102 - life expectancy does not exceed 1,000,000 times

Class 103 - life expectancy is less than 500,000 times

Class 104 - life expectancy is less than 100,000 times

Class 105 - life expectancy is less than 500. This classification is for prototype molds, which are the cheapest.


Ⅱ. Factors affecting the longevity of the injection molding mold

1. Operating conditions - the operating conditions of the injection molding mold must have a corresponding impact on the service life of the mold.


2. Time between production runs - in general, the shorter the time between runs, the shorter the life of the die. It is unlikely to maintain the mold fully between each cycle because the production interval is short.


3. Cycle time - both longer and slower cycle times can reduce the burden on molds, which can help them prolong the molds' life in turn. The length of cycle time mainly depends on the mold design, including wall thickness and design complexity.


4. Injection mold material - the material used to make the mold could affect its life. For example, the life of aluminum molds will not be as long as steel molds. The material of injection molding also has an impact on the service life.
