Bonding of Materials with Induction Heating

A method of producing a bonded product by electric induction heating, the method comprising the steps of:

• placing an electrically conductive sheet between a first induction heating plate and a second induction heating plate disposed within a separable frame;
• supplying ac current to one or more induction heating coils in the first and second induction heating plates to establish magnetic fields that couple with the electrically conductive sheet to inductively heat the sheet;
• separating the first induction heating plate and the frame from the second induction heating plate;
• and
• pouring a liquid bonding material into the volume bounded by the frame and a surface of the electrically conductive sheet.

An electric induction bonding apparatus comprising:

• a first induction heating plate having an indented surface area for placement of an electrically conductive sheet, the first induction heating plate comprising one or more first induction coils disposed within a heat resistant material;
• a second induction heating plate having a surface area substantially the same as the indented surface area of the first induction heating plate, the surface area of the second induction heating plate selectively locatable over the indented surface area of the first induction heating plate, the second induction heating plate comprising one or more second induction coils disposed within a heat resistant material;
• a frame disposed around the second induction heating plate, the frame selectively locatable over the surface of the first induction heating plate;
• and
• at least one or more ac power supplies connected to the one or more first and second induction coils.

• pressing the electrically conductive sheet into an indentation in the first induction heating plate with the second induction heating plate;
• moving the second induction heating plate away from the electrically conductive sheet;
• and
• pouring a liquid bonding material into the indentation over the electrically conductive sheet.
