ABSTRACT:
A process for making metallized plastic molding pellets comprising: first metallizing a laminated plastic sheet by sandwiching an electrically conductive metal foil in between two plastic films; secondly slicing the metallized laminated plastic sheet into a plurality of metallized plastic strips; thirdly wetting and binding the metallized plastic strips, which are radially arranged, with a thermoplastic resin matrix to form a metallized plastic bar by pultrusion processing; and finally cutting the pultruded metallized bar to obtain homogeneously metallized plastic pellets for making effective EMI shields.
