I was asked this question the other day…
Does it make any sense to perform a load sensitivity test on a electric machine?. I did few tests, but results were very good, range 0,016% to 0,105%.
Note: The Dynamic Load Sensitivity Test measures how much the injection time shifts with a change in resistance.
Most all-electric molding machines perform very well in the Dynamic Load Sensitivity Test. In most cases, a variation over 1% is very uncommon in newer machines.
In general, load sensitivity is not a concern with all-electric injection molding machines. Such tests are helpful once or twice a year as part of the general machine maintenance program. This will help you maintain a record of the machine’s performance, and will help you monitor or detect any degradation in performance over time.
