I have a customer who has a blister, in the same spot, everytime after the mold warms up. Then he says they load new material in the hopper and the problem goes away for awhile. Duh!! It's not the material change that fixed it, it's the fact you allowed the steel to cool down!!! How can the molder not figure this out and still think our material is contaminated and smart enough to cause the issue in the EXACT same place everytime!!!!

Who would want to to take on the blame for redoing and expensive process? If they can make a shorcut work most of the time, then they might figure it's worth it, especially if the client buys their excuse on ocassion.
And if it's not the process, they certainly dont want to replace thousands of dollars of equipment. Finger pointing often works.

NO, I am not an engineer and know very little about moulds.
I did do some research on Mould Injection for a project.
The only "common sense" answer I can think of is, 1, The mould may be flawed in that particular spot, which should be easily recognized. 2, Old existing residue may not have been cleaned and removed properly. I've learned over my life that there is no magic or witchcraft involved in problems. Is there only one mould existing? If another, does the same problem exist?

Because the man that runs the machine is not often an engineer, but a facilities guy. A major part of engineering is learning how to deal with high level functions and then explain them to lower functioning people

most production guys think they know everything about everything without ever taking time to run the process...suggest lower hot runner temps or increasing the cooling if equiped....other than that, it sounds like they are content to be run by the machines

Is is always easier to blame the other guy ... specially when someone doesn't know how to fix the problem and doesn't want to admit he doesn't know.
