Abstract
A method of molding a plastic component having first and second portions interconnected by a transition zone with a barrier material encapsulated in the plastic material of both of the portions of the component. The permeable barrier material is placed in a mold cavity to divide the cavity into first and second portions. The first portion of the cavity is filled with plastic material while the second portion of the cavity is filled with plastic material to permeate the barrier material with plastic from both portions whereby the barrier material defines the transition zone and is encapsulated in the plastic component.
