A component is made of at least two segments connected to one another in a movable manner via one or more connecting elements. The component is made of a casting or parts of a casting which is cast in the casting space of a casting mold. The component is longer than the maximum extent of that casting space when the component is aligned via the movable connecting element(s), such that it attains its maximum length L along an axis A. A process for producing the component is also provided.

Provided herein are curable compositions useful for, among other things, making three-dimensional parts by additive manufacturing. The compositions when cured exhibit a surprising balance of improved tensile strength and percent elongation.

There is provided a clip holding unit 50 to be used during a foam molding of a seat pad 20, and the seat pad 20 includes a clip 24 used for attaching a seat cover 18 to the seat pad 20. The clip holding unit 50 is provided in a lower mold 42 of a molding mold 40, and holds the clip 24 during the foam molding. The clip holding unit 50 includes a locking portion 54 to be sandwiched between a pair of locking pieces 30 of the clip 24; a base portion 55 extending from the lower mold 42 to the locking portion 54; and an eaves portion 56 projecting laterally from the base portion 55 as going upward from below.

A method includes 3D printing a mold body from polycarbonate to form a cavity surface and 3D printing a permanent hydrophobic structure of polycarbonate on the cavity surface. The hydrophobic structure comprises a plurality of regularly shaped protrusions extending from and spaced 0 mm to 1.5 mm apart on the cavity surface. The patterned protrusions impart permanent hydrophobicity to the mold cavity surface.

A linerless composite tank for a waste or water system on board an aerospace vehicle includes a monolithic tank body having a first composite material co-cured with a second composite material. The first composite material includes a first resin and the second composite material includes a second resin that is different from the first resin. The first composite material forms an innermost surface of the monolithic tank body defining a tank chamber of the monolithic tank body. A method of manufacturing the linerless composite tank includes providing a mold having a desired interior shape of the monolithic tank, applying the first composite material to the mold, applying the second composite material to the mold, and co-curing the first composite material with the second composite material to form the monolithic composite tank.

Provided is a method of additively manufacturing an object having a particle surface coating thereon, using an intermediate object produced in an additive manufacturing process by light polymerization of a dual cure resin, the intermediate object having residual dual cure resin from which it was produced remaining on a surface portion thereof in unpolymerized form; forming a solid particle coating adhered to the resin coating film; and then further curing the intermediate object.

A sealing element for a molding machine comprises a base body with an inner receptacle wherein the base body is provided with a venting duct to connect an inner receptacle of the sealing element with an outer surface thereof.

A method for molding a seamless rebonded foam article with an internal cavity is provided. The method may include moving a middle mold to a middle mold form position within the mold cavity to press into a first portion of rebond foam particles, and moving a top mold to a top mold form position within the mold cavity to press into the second portion of rebond foam particles. The method may further include injecting steam into the mold cavity at a middle mold fluid port interface of the middle mold such that the steam passes into the mold cavity to interact with the first and second portions of rebond foam particles via at least one middle mold flow hole in the middle mold, and evacuating the steam via a vacuum source coupled to the top mold and the bottom mold.

A seat pad (1) includes a surface portion (1a) configured of a polyurethane foam (11). In the surface portion (1a), wiring grooves (2) for wiring a wire harness (3) are formed. Each wiring groove (2) has a groove width W narrower than the diameter (3) of the harness (3), and a groove depth (D) deeper than the diameter 3 of the harness (3). A seat pad manufacturing method uses, as a molding die, a molding die that has groove-forming protrusions to form the wiring grooves (2) and has holes formed in side surfaces of the groove-forming protrusions. A polyurethane foam material is supplied to an interior of the molding die, and when a molded product is removed from the molding die, molded portions formed in the holes are forcibly pulled out of the holes of the groove-forming protrusions.

Cover lens (1), for a motor vehicle light, wherein the cover lens (1) has an inner surface (2), an outer surface (3) opposite the inner surface (2), a transparent body (4), an opaque body (5) and a coating (6), wherein the coating (6) has PU polyurethane, wherein the transparent body (4), the opaque body (5) and the coating (6) are produced in one continuous piece, preferably in an injection moulding process, in such a way that the outer surface (3) is only formed on the coating (6) and on the opaque body (5), wherein the coating (6), as seen from the outer surface (3) in the direction of the inner surface (2), completely covers the transparent body (4) and only partially covers the opaque body (5). Injection moulding process and injection mould (100) for producing a cover lens (1).
