I didn't ask a question. I just shared info for what I've found to be the best way to avoid denting on some molds. Every mold injects differently. Some molds are more problematic than others for denting. It depends on the cavity shape and layout of the mold. You have to force more hot plastic into the cavities as the plastic cools and shrinks in the cavities. Watch the plastic in the injection port and runner of the mold after its injected and you can see the plastic shrink as it cools.
