MOLDED METALLIZED PLASTIC ARTICLES AND PROCESSES FOR MAKING THE SAME ABSTRACT Molded, one-piece articles having selected surfaces suitable for adherent metallization, molded, metallized, one-piece articles, and processes for making the articles are disclosed. The molded one-piece articles may be formed by: molding into a first mold cavity a first portion of the article using a first electrically insulating material which is an amorphous polymer resin capable of adhesion promotion by an adhesion promotion process and is catalytic for adherent metallization or is capable of being rendered cataltyic for adherent metallization by an activating process; inserting the first portion into a second mold cavity; and molding into the second mold cavity a second portion of the article using a second electrically insulating material, leaving selected surfaces of the first portion exposed. The second material is crystalline polymer resin resistant to the adhesion promotion process employed for the first material, non-catalytic for, and incapable of being rendered catalytic for, adherent metallization by the activating process employed for the first material. The exposed surfaces of the first portion of the article then may be metallized, for example, by electroless deposition to form the metallized one-piece article.
