  • Patent number: 5204127
    Abstract: There is provided by the present invention a compression molding tool for producing apertures of a desired configuration in preselected locations in a compression molded article and a method for producing the apertures. The tool has first and second relatively movable tool halves each supporting a mold section. The mold section associated with the second tool half includes a movable portion that is relatively movable with respect to the second tool half. The first tool half is moved relative to the second tool half until the first and second mold sections engage each other to form a mold cavity therebetween. Devices for creating apertures are included on at least one of the mold sections and are extended into appropriately configured receptacles in the other mold section after the mold sections are engaged, but before molding material is forced by compression into the mold cavity.
