Abstract:
1. A method for thermoforming a plastic material defining integral first and second regions, comprising: a. positioning the plastic material adjacent a surface of a mold so that the first region contacts at least one plug extending from the surface of the mold; b. positioning an energy sink adjacent the plastic material so as to align first openings of the energy sink with the first region; c. supplying energy from an energy source positioned opposite the energy sink from the plastic material, with some of the supplied energy passing through the first openings in order to heat the first region of the plastic material; and d. evacuating the mold so as to thermoform the first region but not thermoform the second region, with the second region contacting the surface of the mold.
