Abstract: The invention relates to an injection-molding tool and to a process for producing pin-shaped blanks as end products, a two-dimensional skin cavity and blank cavities connected to said skin cavity being provided at a runner, in order to be able to form a molding, including a sprue, a skin and the blanks formed on said skin via defined predetermined breaking points. In this case, the injection-molding tool makes it possible before and at the beginning of the injecting operation to create a negative pressure in the cavities and makes it easier after the molding material has solidified to demold the molding obtained by introduced compressed air. In this case, the injection-molding tool is constructed in such a way that the demolding of the blanks is performed separately from the demolding of the skin and the sprue, the demolding also being accompanied by detachment of the blanks from the skin by the lifting movement during the opening of the injection-molding tool, and the blanks being discharged with preference without being acted upon by a manipulator, on account of the loss of form fit and under the action of gravitational force, and the injection-molding tool being made operationally ready again at the end of the cycle by a closing operation.

Abstract: Method for producing a one-piece stopper with a carrier body of an elastomeric material and an inert layer, the carrier body having a disk-shaped outer portion and an inner portion that protrudes in the manner of a spigot from the outer portion. The inner portion is molded under the effect of heat in a molding tool from a sheet of elastomeric material and an inert film and subsequently punched out. The outer portion is molded onto the inner portion by means of injection molding, whereby the stopper is given its final form.
