Note: Metal to plastic bonding of beer kegs
Objective:
Bond an aluminum mesh to a plastic beer keg
End Product:
plastic beer keg
Equipment:
Ambrell 2 kW, induction heating system, equipped with a remote workhead containing two .33μF capacitors (for a total of .66μF).
An induction heating coil designed and developed specifically for this application.
Materials:
Aluminum mesh
Plastic keg 320 mm (12.5 in) ID
Temperature:
250 °C (482 °F)
Frequency:
207 kHz
Testing:
A single-turn solenoid coil is placed around the assembled beer keg and heated for 35 seconds as the keg is rotated. Pressure is applied with a press on the top rim whilst the keg is rotating, forming a seal between the aluminum mesh and the two halves of the beer keg.
Benefits:
Induction heating provides:
-
Quick, reliable, repeatable heat
-
Localized, precision heat to the mesh area
