This is often the case because a process was developed with a given set of barrel temperatures, screw recovery speed, screw style, and back pressure. All of these process settings will interact to create a melt temperature. Many molders will either completely skip checking melt temperature or check the melt temperature and upon seeing that it is high do nothing. As a result of not caring about melt temperature the rest of the process will need to be dialed in to accommodate the melt temperature.
