I was at a molder the other week who had this common issue…
Our technicians always change the clamp tonnage and it seems to cause problems with venting, actions, and wear. Even the setup guys mess it up.
Once you have determined the tonnage that should be used on a tool, I recommend you put a plaque on the side of the mold stating the tonnage to be used. If the recommended tonnage is stamped right on each tool, it is hard for a technician or setup person to miss it.
If you are having a problem with a specific issue, such as tonnage, always look for a simplistic way to draw attention to it.
