Hot-water temperature control systems

SINGLE Temperiertechnik GmbH introduced hot-water temperature control systems for molds rated up to 225°C/437°F.

SINGLE Temperiertechnik GmbH (Hochdorf, Germany) introduced hot-water temperature control systems for molds rated up to 225°C/437°F. The systems are touted as technically superior and more energy efficient than hot oil and electric heaters and ovens. The company claims that its fluid-based temperature control of molds has many benefits over oven curing. The latter complicates part handling, is highly time consuming and makes process control difficult to manage. Further, an oven’s cooling phase offers no room for active support. In the case of thermoplastics composites, the molding process can benefit from active alternating temperature technology (ATT), recommended for processes that require fast temperature variations within the cycle time. Within seconds, ATT switches between two circuits with cooling fluid of different temperatures and heats or cools the mold. This ensures adequate cooling during the filling phase and sufficient heat during the curing phase.
