Press-Bonding Metal Clips Into Sealers

Objective

To heat metal clips and press-bond them into rubber seals. The metal needs to be heated to 250°F to 350°F with a cycle time not exceeding 3 seconds

End Product

Steel clips and rubber sealer blocks

Equipment

Ameritherm EASYHEAT 1kW power supply including one remote heat station with one 1.2 µF capacitor using a specially designed 3-turn pancake coil

Materials

Steel clips and rubber sealer blocks

Temperature

250°F to 350°F

Frequency

373 kHz

Testing

Heating time of 1.5 seconds was attained; shorter heating times are possible due to fast response of the power supply. Bond formation is acceptable due to the even heat pattern produced through induction heating.
