3. Coupled transfers within the part

In addition to the coupling of heat transfer between part and tool, there is also the coupling within the polymer itself between heat transfer and crystallization kinetics (in the case of a semi-crystalline polymer), as well as the dependence of polymer properties on temperature, pressure and crystallinity variables. At thermal level, the four main stages of the cycle (injection / compaction / isochore cooling / ejection) can be observed on mold surface temperature as well as on mold cavity pressure (figure 5 and figure
