Bonding Steel Into Rubber With Induction Heater

Bonding Steel Into Rubber With Induction Heater 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 Material Steel clips and rubber sealer blocks Temperature 250°F to 350°F Frequency 400 kHz Equipment DW-UHF-4.5kW power supply including one remote heat station with one 1.2 μF capacitor using a specially designed 3-turn pancake coil Process As illustrated below Results 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.
