Demand-Based Pulse Temperature Control in High-Pressure Die Casting
RHYTEMPER HotPulse individually controls heat removal from each temperature control circuit of the die casting die. By adjusting the cooling times according to the cycle, heat removal is specifically adapted to the thermal requirements of the respective die zone. Particularly in high-pressure die casting (HPDC), this enables targeted thermal management of die areas subject to different thermal loads.
A thermal reference state can be derived from the continuously monitored temperature and flow rate values. Deviations, for example due to changing cooling water conditions, deposits or reduced flow rates, are detected at an early stage. HotPulse adjusts heat removal from the individual circuits accordingly, supporting stable thermal process control.
Current product documentation reports cycle times that are on average 20% shorter with RHYTEMPER pulse temperature control. At the same time, individual control supports consistent component quality and an economical die casting process.
Early Detection of Process Deviations
Continuous monitoring of flow rate and temperature provides transparency in every individual temperature control circuit. Individual limit and tolerance ranges make deviations visible at an early stage and enable graduated warning and alarm messages.
Critical changes such as significant reductions in flow rate, hose ruptures or detectable leaks can prevent shot release via the machine interface. This helps protect the die casting die, reduce unnecessary scrap and support stable series production.
Flexible Control for Different Process Requirements
Different operating modes are available depending on the die casting application. Control can be based on heat value or return temperature, predefined valve opening times or extracted energy. Continuous cooling is also available.
This enables heat removal from the individual temperature control circuits to be specifically adapted to different die areas and process requirements.
Central Monitoring and Control of Process Data
The RHYTEMPER control system provides a clear overview of temperature and flow rate values and enables direct access to the individual temperature control circuits. Individual limit and tolerance ranges as well as die data sets support reproducible process control.
The 15.6" panel also provides functions such as the integration of die cooling plans, individual circuit labelling and leakage monitoring, as well as optional thermographic monitoring and remote maintenance access. Appropriate interfaces enable the system to be integrated into the die casting machine control system and higher-level process data acquisition.
