ABSTRACT:
A gas-assisted injection molding article suitable for plating and a method for plating the article is disclosed. A sleeve is selectively mounted on an upstanding gas injection stud formed on the molded article. The sleeve seals an aperture which extends through the sidewall of the gas injection stud to the hollow interior of the molded article. The sleeve is preferably formed of a heat shrinkable thermoplastic. After the sleeve has been mounted to the article, the sleeve is subjected to a source of heat such that it retracts and is securely mounted to the gas injection stud. With the aperture sealed, the article can now be submerged in a suitable plating bath or other liquid medium.
