Mold including a first shell having a cavity, a second shell having a projection, and an intermediate shell having a projection suitable for being coupled in the cavity of the first shell and a cavity suitable for being coupled with the projection of the second shell. The second shell includes a first injection channel extending from an inlet hole in a side wall of the second shell to an outlet hole in the projection of the second shell. The intermediate shell has a second injection channel extending from an inlet hole in a side wall of the intermediate shell to an outlet hole in the projection of the intermediate shell.

A method for producing a package closure having a neck, a cap and an axis (A) includes a) by means of movable jaws and a tool core forming the neck with an outer thread and the cap with an inner thread, wherein an interior of the neck is formed by an outer first tool core part, and wherein an interior of the cap is formed by an inner second tool core part and a third tool core part, the thread of the cap being formed by the third tool core part, b) removing the jaws from the formed package closure, c) axially displacing the second tool core part in relation to the first tool core part and thereby separating the cap and the neck, d) axially displacing the third tool core part in relation to the second tool core part and thereby disengaging the cap from the third tool core part while keeping the second tool core part engaged with the cap, e) displacing the neck axially in relation to the cap and bringing the thread of the cap into engagement with the thread of the neck through an inherent flexibility of the package closure to form a package closure having a cap mounted on the neck, and f) displacing the package closure in relation to the second tool core part to disengage the package closure from the tool core.

A manufacturing process for an active grille shutter arrangement including in-mold assembly of an active aero hinge modular frame that allows for the joining of multiple components that are to be assembled directly out of the molding process tooling. These components could be the vane end pivots, vane end stops, drive linkages, frame end stops, etc. Final assembly of the system is facilitated by geometrical considerations and molding material considerations in the in-mold assembly (IMA) design.

Mold including a first shell having a cavity, a second shell having a projection, and an intermediate shell having a projection suitable for being coupled in the cavity of the first shell and a cavity suitable for being coupled with the projection of the second shell. The second shell includes a first injection channel extending from an inlet hole in a side wall of the second shell to an outlet hole in the projection of the second shell. The intermediate shell has a second injection channel extending from an inlet hole in a side wall of the intermediate shell to an outlet hole in the projection of the intermediate shell.

A method of producing a package closure (10) of plastic material by means of a mould comprising movable jaws (35, 36), a counterpart (37), an outer first tool core part (38), an inner second tool core part (39) and an ejector (40), wherein the outer first tool core part, the second tool core part and the ejector are axially displaceable relative each other, comprising the steps of axially displacing the outer first tool core part and the second tool core part in relation to each other in a first direction, thereby disengaging the cap from the outer first tool core part while keeping the inner second tool core part engaged with the cap, and then axially displacing the inner second tool core part and the outer first tool core part and/or the ejector (32) in relation to each other in the first direction or in an opposite second direction while folding a foldable portion (21) of the package closure inward through an inherent flexibility of the package closure (10), Disclosed is also a device for producing the package closure (10) and various embodiments of package closures.
