The fill time for a four-cavity mold is 4 seconds. When one cavity is blocked, what should the fill time be?
Understand the Problem
The question involves determining the fill time of a mold when one of its four cavities is blocked, given that the fill time for all four cavities is 4 seconds. We need to consider how blocking a cavity might affect the fill time in a practical scenario.
Answer
4 seconds
The final answer is 4 seconds

The final answer is 4 seconds
More Information
When one cavity is blocked in a multi-cavity mold, the fill time for the remaining cavities generally stays the same, assuming the injection pressure and flow rate are maintained. The pressure will increase to fill remaining cavities.
Tips
It's a common misconception that blocking a cavity will proportionally decrease fill time; however, the fill time is determined by injection speed.
