A Piezoelectric Sensor Based Smart-Die Structure for Predicting the Onset of Failure During Die Casting Operations

Colorado School of Mines

Contact CSM About This Technology

Technology Marketing SummaryThis invention provides a method for embedding a failure predicting mechanism within the working surface of die casting dies for molten metals.
DescriptionThis is done using a piezoelectric thin film sensor that can be use with any coating system for the die.  The sensor would detect the onset of failure in the protective layer by the sudden increase in stress level, which always accompanies such failure.  The sensor can then facilitate precautionary measure to be adopted.Benefits
  • Senses failure before traditional methods
  • Can be used with any coating system
  • Allows for unmanned monitoring of machining systems in production lines
Applications and Industries
  • Manufacturing industry
  • Steel industry
  • Die cast and coating companies
