ApplicationsHeat and Bend aluminium Parts

Application: 

A manufacturer heating aluminium prior to bending it to create custom parts.

Problem: 
  • Slow Line Speed - The existing method of heating the aluminium in a gas-fired convection tunnel limited the line speed to 50 feet (15.2 meters) per minute.
  • Poor Quality - The existing heating method resulted in stress marks and other imperfections in the bent aluminium parts.
  • Excessive Scrap - An excessive number of parts (five percent) had to be scrapped due to the poor bend quality achieved with the existing heating method.
Solution: 
  • Heat - A Model 4554-A-10-06 High Density Pyropanel was used to heat the
  • aluminium to the proper temperature (above 235F [113C]).
  • Power Control - A Model 664F Phase Angle SCR Power Controller controlled the power to the heater.
Benefits: 
  • Increased Line Speed - Line speed increased to 95 feet (29 meters) per minute using the High Density Pyropanel.
  • Improved Quality -Heating the aluminium with the High Density Pyropanel eliminated the stress marks and other imperfections in the bent aluminium parts.
  • Reduced Scrap - The scrap rate was reduced to less than one percent with the new heating system.
