The figure below shows a typical process window generated at the molding
machine.
How to use this information:
The process window is an indicator of how much can you vary your process and
still make an acceptable part. An ideal situation is you have a wide process
window. If the process window is very narrow, then there is always a danger of
molding parts with defects. For example in the above graph, if the process
window is very small, then one could get occasional short shots or occasional
flash due to the natural variation in the process. A robust process is one that
has a large process window and accommodates the natural variation.
