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 .66 µF).

• An induction heating coil designed and developed specifically for this application. 

Materials

• Aluminum mesh

• Plastic keg 320 mm (12.5”) ID

Temperature

250 ºC (482 ºF)

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
