Monitoring mold deformations in aluminum die-casting

When aluminium die casts are produced, liquid aluminum is moulded under high pressure and the mold halves are held together with a significant force. During this process, the tool halves are pressed apart minimally, which may also cause fraying on the component, if the gap is too large. Also, presense of aluminium residues after the process leads to increased wear and decreases the life of the tool. As a result, tool deformation is monitored using inductive sensors.

In this setup, generally, three to four eddyNCDT 3005 eddy current systems are required to ensure consistant gap monitoring. These sensors are compact in design containing a robust controller and providing resistance to extranal factors, making the system insensitive to harsh industrial environments. These sensors can be easily integrated into an existing machine and provide accurate results regardless of the operating environment.
