A method of forming a threaded bore in a compression molded part comprises: positioning at least one rotatable threaded shaft in a mold cavity during compression molding of a part; rotatably driving the at least one threaded shaft for unthreading the at least one threaded shaft from the part; and pushing the at least one threaded shaft away from the mold cavity once the at least one threaded shaft is unthreaded from the part.

A pacifier and a method of making a pacifier. Two or more separate silicone-based materials are joined together with a compression mold such that the pacifier defines a unitary structure where gaps and related crevices associated with multi-piece pacifier construction are avoided while still permitting artwork, differing colors or other aesthetically-pleasing indicia. In one form, one grade of silicon may be utilized in a region of the pacifier that is placed within a baby's or child's mouth, while another grade of silicone material may be used in a region of the pacifier that is not normally associated with placement within a baby's or child's mouth. The aesthetically-pleasing indicia that is formed in or on the pacifier is achieved without recourse to painting, labels, appliques, embossing, decals, stickers or other affixable or markable medium.

A method for making a cap for a container, comprising a step of forming in which the following are: a body, configured to be coupled and uncoupled relative to the neck of the container and including a side wall, which extends around a longitudinal axis, and a transverse wall; a tamper evident ring, configured to remain anchored to the neck of the container even when the body is uncoupled from the neck and including a joining portion where the tamper evident ring is joined to the body, the joining portion being configured to be torn along a full perimeter surrounding the longitudinal axis, wherein the cap comprises a connecting band having a first end connected to the side wall of the body and a second end connected to the retaining portion of the tamper evident ring.

Provided is a compression molding die. The die can be used for compression molding an I-shaped part without the need for machining. The molding die comprises: an outer mold with an inner diameter of d; an upper pressing disc, a lower pressing disc and a huff mold with the same outer diameter of d and the same inner diameter of f; an upper mold; a lower mold; and a core mold with a diameter of h. The upper pressing disc, the huff mold and the lower pressing disc, which are movable vertically, are arranged in the outer mold in a vertically spaced manner; the vertically movable upper mold extends into the upper pressing disc, and the vertically movable lower mold extends into the lower pressing disc; the outer mold, the upper mold, the upper pressing disc, the huff mold, the lower pressing disc and the lower mold define a cavity.
