20230191672 · 2023-06-22 ·

An injection molding device with a middle mold part arranged in a first direction between first and second outer mold parts that are linearly movable with respect to the middle mold part in the first direction between open and closed positions. One or more side face regions of the middle mold part is configured to receive and hold in a lateral position a cavity module from outside of the injection mold during injection molding. A first cavity arranged in the cavity module at least in the closed position of the injection mold communicates with a first cavity half of a second cavity. At least one of the outer mold parts includes a second half of the second cavity, which interacts with the first half to form the second cavity to receive a liquefied plastic material and to form a second component interconnected to the first component.

Two piece housing assembly with elongated attachment and method for making the same

A first part having an attachment having an elongated body configured to release from a second attachment of a second part under a desired force, and a method of manufacturing the same is provided. The first attachment includes a generally elongated body extending outwardly from the first wall with respect to the first support surface, the first wall further including at least one indent, the at least one indent formed on the first wall and open to a peripheral side edge of the elongated body, the indent extending into the wall a predetermined depth so as to provide the elongated body with a predetermined resiliency.

Modular mold system

A modular molding system having a mold base assembly for assembling an interchangeable mold insert assemblage. The assembled mold insert assemblage defines an internal cavity for forming a molded object. Each mold insert assemblage can be disengaged from the mold base assembly and exchanged with a different mold insert assemblage having an internal cavity having different dimensions.

20170348889 · 2017-12-07 · ·

An injection molding tool for producing a molded part and a corresponding method are disclosed. The injection mold tool comprises a first tool mold half and a second tool mold half, which together with a first slider and at least one second slider define a free space for the molded part to be produced. A lever which is pretensioned with an elastic element is assigned to an end switch such that a movable and free end of the lever cooperates with the end switch due to a movement of the first slider.

Cover panel for at least one display instrument in a vehicle

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.

METHOD FOR CONVERTING A DESIGN OF AN ORIGINAL PREFORM AND A RELATED MOLD STACK FOR THE MOLDING THEREOF

Disclosed herein, amongst other things, is a method for converting a design of an original preform that is blow moldable to form a container into a converted preform having less molding material that is blow moldable to form the same container. The method includes retaining a neck finish and body of the original preform on the converted preform. The method further includes replacing the original base of the original preform with a converted base having an outer base surface that joins with an outer body surface of the body at an base split-line of the original base and that fits offset within an outer body surface of the original base, whereby the converted preform has a reduced total length, disregarding any gate vestige that may be formed thereon, relative to a total length of the original preform.
