Metall-Kunststoff-Verbindungen von Bierfässern

Metal to plastic bonding of beer kegs

Objective: Bond an aluminium mesh to a plastic beer keg.

Frequency: 207 kHz

• Ambrell 2 kW induction heating system, equipped with a remote workhead containing two 0.33 μF capacitors for a total of 0.66 μF;
• An induction heating coil designed and developed specifically for this application.

Material: Aluminium mesh, plastic keg 320 mm (12.5”) ID.

Temperature: 482 °F (250 °C)

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 aluminium mesh and the two halves of the beer keg.

• Quick, reliable, repeatable heat;
• Localized, precision heat to the mesh area;
