Effects of process parameters on tooling.
My interests is in keeping molds in "ready to run" condition. The issues I deal with regularly are "drags" "PL flash" and "Hobbed (or Coined) parting lines" Obviously clamp tonnage is a requisite for making good parts. I see conversations (here and elsewhere) about fill & pack studies, gate freeze studies etc, how much attention is paid to sufficient but not excessive clamp tonnage? What precautions are being observed to protect expensive tooling from unneccesary damage? All the defects listed above are either directly or indirectly the result of excess tonnage.
