Mhira3D: thermal anomaly detection. New features for quality die-casting

Mhira3D, a vision system for the die-casting industry developed by Imago, is able to perform a 3D integrity analysis and verify the completeness of the print as soon as the part is extracted from the press and is still in the robot gripper. At the same time, the thermographic map of the part is examined in order to detect thermal drifts and keep the process monitored.

Among Mhira3D's latest R&D achievements is thermal anomaly detection, developed and tested on real production data.

Mhira3D's thermographic analysis, carried out at every shot, is an innovation that can provide support on multiple fronts. Thanks to the thermographic map, the operator can locate areas where overheating is occurring and identify problems related to lubrication or cooling. Continuous in-process temperature monitoring is critical to highlighting anomalies that could lead to part non-conformity, allowing events such as machine downtime to be prevented.

What do we guarantee?

• thermal variations monitoring of the process starting from any visible zone of the part, for example in some points of the lubrication areas, so as to detect any drifts in advance;
• customer support for studies and analysis of the most critical areas of the part during the thermal process.

How does it work?

• the user sets one or more areas in correspondence of the critical zones on the part just extracted from the press;
• during the production process, the system monitors the temperature trend in each area;
• the user can set some parameters for the management of the algorithm, such as frequency and number of consecutive anomalies;
• the software returns a specific signal in case of abnormal temperature detection;
• the system sends notifications in real time via e-mail or instant messaging applications.

The new functionalities show even more Mhira3D's added value, which guarantee the maintenance of high production standards and the considerable saving of resources.
