The Average temperature, part result is the average temperature of the temperature profile across the part thickness, calculated at the end of cooling time.
This profile is based on the average mold surface temperatures for the cycle, which includes the clamp open time.
The average temperature should be about half way between the target mold temperature and the ejection temperature for an optimized mold. There should be only a small variation in average temperature in the part. Areas of high average temperature may be thick regions of the part or areas that are poorly cooled. Consider adding cooling channels near these areas.
