摘要:
A method of forming an item with electromagnetic interference shielding, the method including the steps of: inserting a first polymer into a first compounding extruder, wherein the first compounding extruder provides a first melted charge; inserting the first melted charge into a second compounding extruder, wherein the second compounding extruder introduces a plurality of conductive fibers into the first melted charge and wherein the second compounding extruder provides a second melted charge comprising the first melted charge and a plurality of conductive fibers; depositing the second melted charge onto a least one die of a compression mold; and closing the compression mold about the second melted charge in order to form the item.
