Induction welding apparatus and method

摘要

An apparatus and method for welding or thermally bonding parts of thermoplastic material by subjecting a die to high frequency electromagnetic radiation to effect heating thereof and heating of thermoplastic parts in contact with the heated die. The die is continuously cooled to permit rapid cooling thereof and of the parts in contact therewith upon deenergization of the source to reduce cycle time and facilitate automated production techniques using a single source and multiple die stations successively exposed to the source for heating and being rapidly cooled thereafter due to the continuous cooling thereof.
