Abstract:
A method of bonding multiple polymeric elements using a molding device comprising first and second mold components, the first mold component designed to hold the multiple polymeric elements and the second mold component, the method comprising:distributing a first set of ferromagnetic particles comprising a first Curie temperature through the first mold component, and a second set of ferromagnetic particles comprising a second Curie temperature, different from the first Curie temperature, through the second mold component; placing first and second polymeric elements into operative association with the molding device with the first and second polymeric elements between the first and second mold components; exposing the molding device to an electromagnetic field, thereby heating the molding device; and heating and bonding the polymeric elements by way of contact with the molding device.
