Self-Learning Control Algorithm for Temperature-Controlled Hot Runner Balancing
At Fakuma 2024, Kistler presents the new ComoNeo 7.0 process-monitoring system with the Multiflow 2.0 feature update for consistent temperature control in multicavity molds.
At Fakuma 2024, Kistler shows the latest ComoNeo 7.0 process monitoring system with the Multiflow 2.0 feature update. Kistler describes the feature as a self-learning control algorithm for temperature-controlled hot runner balancing. The fully automatic adjustment feature is intended to ensure consistent temperature control in multicavity molds. Multiflow 2.0 can also stabilize the production process, including during lot-to-lot material fluctuations.
Kistler also features its AkvisIO IME (Injection Molding Edition) data analysis software. Using either traditional statistical methods or data-driven artificial intelligence, the software enables users to analyze process and machine data. Featuring simplified integration into Kistler devices — such as ComoNeo and ComoScout — by utilizing communication standards such as the Ethernet-based Euromap 77, the technologies enable the machine to become the data source and AkvisIO the single source for reliable production data.
In optical quality inspection, Kistler shows the KVC 821 and KVC 121 standard quality inspection systems. These enable molders to measure and inspect the surface and dimensional accuracy of up to 750 parts per minute using up to eight cameras in 2D, 2.5D or 3D. Kistler notes that its automated vision offerings are customized, robot-integrated packages that enable fully automated sampling. At the show, Kistler gives a live demonstration of how the KVC 821 optical quality inspection system examines injection molded parts for surface defects and dimensional accuracy using variable camera systems, a variety of inspection methods and AI-based anomaly detection.
In sensing technology, Kistler presents what it calls the world’s smallest cavity pressure sensor. The 6183D, which has a diameter of just 1 mm, takes measurements within a range of 0 to 2000 bar (0 to 29,000 psi) at a maximum melt temperature of 450°C (842°F). The 9239B miniature longitudinal measuring pin, which can be installed 2 to 4 mm behind the cavity wall, measures the pressure-induced expansion of the mold in a noncontact fashion. This protects the sensor from direct contact with the melt and means the sensor won’t leave an imprint on highly cosmetic plastic parts. Also present, the 6184A cavity pressure sensor with lateral cable outlet. The 3-mm diameter sensor is well suited for high-cavity molds and small inserts. The 1720A conductive spacer sleeve, which makes it easier to install and maintain wireless cavity pressure sensors in insert molds, is also on display.
