Temperature Control Technology with Rhytemper® Temperature Control: Ensure process stability, shorten cycle times, and reduce unit costs!

The unit costs of die-cast and injection-molded parts are largely determined by mold temperature control! This is because mold temperature control has a direct impact on process stability, product quality, and cycle time. 

Conventional through-feed temperature control systems usually unnecessarily extend cycle times, do not allow for monitoring of product quality, and do not ensure process stability.
The Rhytemper® temperature control system, on the other hand, ensures temperature management that is optimally tailored to the molded part. With this system technology, the manufacturing process is managed in such a way that process stability is ensured for the entire batch with the shortest possible cycle times and continuous process monitoring, moving production toward zero defects.

Optimal manufacturing process

The best product innovations can only realize their full potential if the manufacturing process is also managed optimally. To achieve the best results for the entire production batch, intelligent temperature control management is essential to ensure that a thermal fingerprint of the molded part is captured and continuously monitored throughout the manufacturing process.
To this end, the "Rhytemper®" temperature control system maps the molded part over the course of the cycle using the heat balances in the individual temperature control circuits of the mold. The water flow rate and temperature difference of each individual circuit are evaluated, thereby mapping the unique thermal structure of the molded part being produced. 

By monitoring the energy balances and adjusting parameters such as temperature difference and flow rate in each temperature control circuit, the system ensures that the thermal fingerprint of the molded part remains constant within an extremely narrow range. In practice, in addition to ensuring process stability and product quality, cycle time reductions of 18% are achieved on average. In some cases, reductions of up to 40% are achieved.
