The most economic answer is not. I mean you don’t need any cooling tower but it depends on the situation and amount of plastic which you are injected in mold.
As I saw different cases for commen mold they don’t use any cooling equipment and plastic cools down itself.

I work as a material handler at a plastic injection molding factory, and we have water lines that attach to the mold and send cool water to it while the mold is closed. A part usually takes 60 seconds per cycle, which is the plastic being injected, cooling, opening, and ejection. When the part drops to the conveyor, it is cooled down enough where you can handle it. I’m not sure about the kw cooling towers per hour though
