Abstract
A molded article containing an electrical element buried therein has at least two leads, and portions of the leads are left exposed. The article is improved in that all of the leads are left confined within the confines of the article, the exposed portions of the leads being disposed within at least one aperture through the article. Also a molding process for making the article useful as a catcher plate for an ink jet printer. Broadly, the process comprises the steps of placing the portions of the leads to be exposed, each in a groove in a post that is part of the mold, and closing the mold cavity with a closure plate containing an elastomeric material aligned with the post and leads, such elastomeric material having a coefficient of thermal expansion that is greater than that of the material used to make the mold.
