An injection-molded component having a casing body of plastics material and a core which is made of a core material, in particular of a metal, which is at least partially received within the casing body and is at least partially insert-molded. The injection-molded component may in particular serve as a joint part of a joint. As a result of the preferably metallic core, the injection-molded component, despite comparatively small dimensioning, is capable of being comparatively highly stressed. By virtue of the casing body of plastics material, a minor actuation noise may be implemented for the joint, even without complex lubrication.

A method of preparing an overmolded optical fiber assembly comprising: (a) placing at least one flexible optical circuit in a bottom mold, said bottom mold defining a bottom overmold cavity having a bottom surface, said at least one flexible optical circuit having a substrate and a plurality of fibers adhered to said substrate, said substrate being disposed within said bottom overmold cavity to define a first space between said substrate and said bottom surface; (b) flowing a polymer in at least said first space; (c) placing a top mold over said substrate, said top mold defining a top overmold cavity and a top surface and a port defined in said top surface to access said top overmold cavity, said substrate defining a second space between said top surface and said substrate; (d) flowing a polymer in at least a portion of said second space; and (e) removing said bottom and top molds to release said overmolded optical circuit.

An imprint apparatus brings an imprint material on a substrate including a first mark into contact with a mold including a second mark and cures the imprint material, thereby forming a cured product of the imprint material on the substrate. The apparatus includes a plurality of detectors used for alignment detection, and a controller configured to obtain a plurality of pieces of relative position information by detecting a relative position between the first mark and the second mark a plurality of times using the plurality of detectors in a state in which the imprint material is cured and a positional relationship between the substrate and the mold is maintained, and to calibrate, based on the plurality of pieces of relative position information, a plurality of detection processing operations each performed using each of the plurality of detectors.

A method of making a prefabricated root section (26) for a wind turbine blade (10) is described. The method comprises: providing a male mould (28) extending longitudinally in a spanwise direction between an inboard end (30) and an outboard end (32) and extending transversely in a chordwise direction between a leading edge (34) and a trailing edge (36), the male mould (28) defining a male mould surface (38) of convex curvature in the chordwise direction; providing a root plate (48) having one or more root inserts (50) projecting therefrom, the or each root insert (50) being arranged along an arcuate path; arranging one or more inner fibrous layers (40) on the male mould surface (38); arranging the root plate (48) at the inboard end (30,) of the male mould (28) such that the or each root insert (50) overlays an inner fibrous layer at the root end of the mould (28). The method further comprises arranging one or more outer fibrous layers on top of the inner fibrous layers (40) and on top of the or each root insert (50), providing resin to the fibrous layers (40) and to the or each root insert (50) and curing the resin to form a prefabricated root section (26) for subsequent use in the manufacture of a wind turbine blade (10). Curing the resin to form the prefabricated root section (26) is conducted before removing the prefabricated root section (26) from the male mould (28).

A method includes disposing fibrous material with a first mandrel, a second mandrel and a first mold section, the first mandrel including a first base, the second mandrel including a second base, and the first mold section including a support surface; arranging the first base on the support surface; arranging the second base on the support surface adjacent a first side of the first base, the arranging including moving the second base along a first trajectory that is substantially coincident with a corner between the first side of the first base and the support surface; arranging a second mold section with the first mold section to provide a mold, where the first mandrel and the second mandrel are between the first and the second mold sections; injecting resin into the mold to engage the fibrous material; and curing the resin to form a composite component.

Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.

A method for producing a spectacle lens 2 including a base portion 2 that is made of a resin material and includes a convex object-side face and a concave eyeball-side face, and an optical element 12 that is made of a material different from the material for forming the base portion and is embedded in the base portion, is described. The method includes: arranging an optical element in a cavity 28 of a mold including a first mold part 20 and a second mold part 24 that can be opened and closed; introducing a resin material for forming a base portion of the spectacle lens into the cavity of the mold; obtaining the spectacle lens by curing the resin material that is a resin for forming the base portion; disassembling the mold; and detaching the spectacle lens from the mold.

A mounting element, i.e., a retaining element or clip, for mounting a terminal element at a component housing of a component body by extrusion-coating the component body at least in part with a coating material, which is designed (i) for holding and positioning a terminal element at a component housing of a component body while the component body is being extrusion-coated with a coating material, and (ii) for accommodating at least in part in the interior of a molding tool during the coating, (iii) which includes at least two support elements, and (iv) in which the at least two support elements are designed so that they are supported at an inner surface of the molding tool when the mounting element is held at the component housing of the component body while the component body and the mounting element are accommodated in the interior of the molding tool.
