Title: Induction Heating for Forming High-Precision Metal Panels

 

Invention: Researchers at the University of Arizona have developed a method for slumping metals and doped glasses that provides controlled heating across the entire piece, allowing for the formation of optical quality objects.  The process is about 10 times faster than the conventional kiln method and requires much less energy.

 

Background: Slumping is a method of forming either glass or metal to the shape of a particular mold. This is typically done in a kiln, but unfortunately, this does not eliminate the risk of uneven heating in a material, which can lead to  imperfect slumping.  In addition, there are intense energy requirements due to the high temperatures needed in the kiln, and the length of time it takes to get uniform heating throughout the material.

 

Applications:

  • Formation of optical grade metal sheets
  • Formation of complex metal sheets
  • Formation of doped optical glass through slumping

 

Advantages:

  • Capable of slump molding complex pieces
  • Potential for the addition of live metrology systems
  • More easily controls temperatures while heating a workpiece
  • Cost effective
  • Faster than convection and radiation heating
