Two Shot Molded Bezel

       A method is described for molding an electromagnetically
(EMC) shielded and decorative bezel in a two-shot mold. When ejected
from the mold, the bezel is one complete piece requiring no further
process.

      The shielded portion of the part (Fig. 1A) is initially molded
using a blend of plastic and stainless steel fibers or nickel-coated
fibers.  The part is ejected from the tool and placed into another
mold and the decorative plastic material (Fig. 1B) is molded on the
substrate.  The bonding of decorative material is accomplished by
using a higher shrinkage material and mechanical locks.  The part is
removed from the mold as a complete part (Fig. 2) providing a
shielded, color- matched, decorative bezel.
