Comparison of different cross-sectional cooling channels for better heat dissipation

The basic principle of injection moulding is that a solid polymer is molten and injected into a cavity inside a mould which is then cooled and the part is ejected from the machine. Therefore the main phases in an injection moulding process involve filling, cooling and ejection. The cost effectiveness of the process is mainly dependent on the time spent on the moulding cycle in which the cooling phase is the most significant step.
