A basic principle associated with injection moulding is usually the entry of a thermal polymer into a Table Mould(FURNITUREMOULD) where it is rapidly cooled to some heat so that it is sufficiently hardened to maintain the contour of the cavity. Therefore, the heat from the table mould is important, in part from the entire moulding cycle. Since the melt moves more freely with the hot mould, a better cooling time is required before demolding to demold. In other words, when the melt hardens from the cavity, it must accept a compromise between the two opposing faces to achieve the desired moulding cycle.

During the cavity filling phase, the hottest material can be near the entry point, the inlet, and the coldest polymer can be at the farthest inlet. However, the heat from the coolant rises as it passes through the table mould. Therefore, in order to achieve a uniform cooling rate over the moulding area, it is desirable to position the incoming coolant fluid near the moulding surface and position the passage containing the „hot“ coolant fluid near the „cooling“ moulding surface. However, as can be seen from the subsequent dialogue, it is very feasible to consider an idealized strategy, and the builder must use a considerable amount of typical meaning when planning the coolant circuit to avoid unnecessary expensive moulds.
