Fountain cooling system

So-called deflection elements (Figure 2.44) or fountain cooling systems are used if the aforementioned elements cannot be used due to insufficient space. The temperature control medium is introduced into the mold core using a transverse baffle or tube, and the heat of the injection is removed over a defined sequence.

Laminar flow is a phenomenon exhibited by plastics as they move through a cavity or runner system. As shown in Figure 3, the outermost laminates of material freeze as they contact the cool mold wall. The next laminates in the channel will then come into contact with the wall and freeze. This continues to happen, leading to a fountain flow of material originating from the center of the channel.
