ComoNeoMULTIFLOW: temperature-controlled hot runner balancing.

As an option for ComoNeo, ComoNeoMULTIFLOW

synchronizes the pressure profiles by individually controlling the

nozzle temperatures on the hot runner. It stabilizes the process

and adjusts for batch fluctuations as well as other process

anomalies.

ComoNeo combines the advantages of automated hot runner

balancing with 100% quality assurance based on cavity

pressure (see the illustration above). The purpose of hot

runner balancing is to ensure identical injection and pressure

conditions in all the mold’s cavities. The control variables used

by ComoNeoMULTIFLOW are the cavity pressure profiles in the

individual cavities. The actuating variables are the temperatures

of the hot runner nozzles.

ComoNeoMULTIFLOW analyzes and compares the measured

pressure curves. Nozzle temperature setpoints are calculated on

this basis and transmitted to the external or machine-integrated

hot runner control system via an interface such as OPC UA.
