ONI Rhytemper® HotPulse

Impulse temperature control for die casting

The RHYTEMPER® multiple circuit temperature control HotPulse regulates the heat content of each individual temperature zone within the tooling. This guarantees a sustainably high product quality and the shortest cycle times.

RHYTEMPER® HotPulse – multiple circuit temperature control for the highest moulded part quality

In contrast to conventional temperature control systems the RHYTEMPER® HotPulse can be installed close to the tooling, protected in a pressure diecast cabinet on the pressure diecasting machine. This enables the exact temperature and flowrate recording and regulation. The diecast cabinet acts as a robust protective housing for the sensor system and the valves.

The modular design with preassembled, housed-in manifold blocks in addition to pre-wired electronic boxes enables space saving installation of the RHYTEMPER® HotPulse close to the tooling. The individual modules, whose number of circuits is tailored to the respective application, are connected to each other and to the main controller via a bus system.

Standards have been agreed with selected pressure diecasting machine manufacturers for the installation of the RHYTEMPER® HotPulse modules directly in the machine manufacturer's works. Thus in the case of new machines the system can already be integrated by the manufacturer at their works and delivered together with the machine – economic temperature control can be that simple!

The operator interface of the RHYTEMPER® HotPulse is simply and clearly designed. The optimum settings for economic temperature control can be undertaken in just a few steps.

The heat level of each individual temperature control circuit is set individually to the respective moulded part-specific requirement and displayed in a coloured bar. Adaptation of the heat level is done quickly and simply via the setting function "hotter" or "colder".

Each temperature control/tooling circuit is allocated an appropriate mode of operation (mode) which is saved as a dataset and can be reactivated at any time.

Furthermore, with the RHYTEMPER® HotPulse numerous other special functions and setting options are available to the experienced application technician.
