Abstract
The present invention teaches an apparatus for producing an article in a mold tool having electrically isolated dies, an electric field generator, and a sleeve made from a material having a very low dielectric loss factor and being operable between an extended and retracted position. The sleeve separates the dies when it is in an extended position and permits an electric field produced by the generator to be coupled between the dies.
