WebBulk temperature is used to indicate the weighted average temperature across the thickness. The temperature of polymer melt changes not only with time and location, but also with thickness during the entire injection molding cycle. It is difficult to illustrate all these changes in a single display. For these reason, Bulk temperature is used.
