Dynamic temperature controller that use rapid alternation between cold water flows and pressurized hot water flows. The dynamic temperature controller Dual T rapidly sends in alternation water flows at different temperatures (hot flow max. 180°C and cold flow min. 8°C). This temperature control unit allows for the injection of plastic into the preheated mould using the hot water flow (obtaining the maximum quality moulded part). Subsequently, by introducing cold water into the mould, it allows to quickly extract the piece as the solidification process of the same is accelerated.
