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.
