This invention relates to a partially plated molded article and to a process for the production of a molded article which is partially plated with metal such as circuit boards, connectors, decorative articles, etc., where a catalyst such as palladium, gold, etc. is added after roughening of the surface of a primary molded article, and then, the molded article is inserted into the mold and a secondary article molded thereabout so that the portions to be plated with metal are exposed, and after such molding, the exposed portions are plated with metal. Alternatively, the catalyst may be applied after molding of the secondary article around the roughened primary molded article. |

DETAILED DESCRIPTION The present invention relates to a first process of molding a primary molded article, conducting a pre-treatment of the primary molded article by adding a catalyst such as palladium, gold, silver, platinum, etc.
after roughening of the surfaces of the primary molded article, forming a secondary molded article using plastic material and a mold on the base of the pre-treated primary molded article where portions of the primary molded article to be plated with metal are exposed, and plating the secondary molded article with metal.
The present invention also relates to a second process of molding a primary molded article having an outer surface and protrusions extending from the outer surface, roughening the outer surface and protrusions of the primary molded article, not adding a catalyst to the outer surfaces and protrusions of the primary molded article after roughening, molding a secondary molded article having an outer surface about the non-catalytically-treated primary molded article such that surfaces of the protrusions are exposed, treating the outer surface of the secondary molded article and exposed protrusion surfaces of the primary molded article with a catalyst such as palladium, gold, silver, platinum, etc.
, washing the outer surface of the secondary molded article to remove the catalyst from the outer surface of the secondary molded article but not from the exposed protrusion surfaces of the primary molded article, and then plating the exposed protrusion surfaces of the primary molded article with metal.
In addition to well-known plastics such as polyamide resin, polyphenylene sulfide resin and liquid crystal resin, also well-known ceramics, etc.
can be used as raw material for forming the primary and the secondary molded articles in both processes of the present invention.
The plastics material includes not only single plastics material, but also those mixed with well-known fillers such as glass fiber, potassium titanate fiber, and so on.
The catalyst treatment mentioned above can be done using conventionally known processes
