Provided are a mold allowing smooth removal of a molded article therefrom without deforming the molded article, and a method of producing the molded article using the mold. The mold includes a first mold piece (A), a second mold piece (B), and a plurality of third mold pieces (C). One of the first mold piece (A) and the second mold piece (B) has a protrusion cavity surface (2f) that protrudes toward the third mold piece (C) from a mating surface (1a) to contact with the third mold piece (C) and shapes an external profile of the molded article (Ma) together with a cavity surface (3f) of the third mold piece (C) when the mold pieces are clamped with each other.

The present invention relates to a method of manufacturing a dental component, in particular a dental prosthesis or a partial dental prosthesis, by means of a dental furnace, comprising the following steps: (i) producing a model of the dental component; (ii) embedding the model in an investment material; (iii) removing the model from the investment material, in particular by heating or burning out, to obtain a negative mold of the model; (iv) inserting a raw material required for manufacturing the dental component into the negative mold; (v) producing the dental component in the negative mold; and (vi) deflasking the dental component in an at least partly automated manner, in particular by means of a stripping manufacturing process, on the basis of a virtual model of the dental component.

A method for fabricating a stiffened panel. Layers of composite material are placed on a surface of an inner-mold-line tool having protrusions that extend from the surface of the inner-mold-line tool. The layers of composite material laid-up on the surface of the inner-mold-line tool are compacted to form compacted layers of composite material. The compacted layers of composite material are cured to form an inner-mold-line layer having corresponding protrusions. The inner-mold-line layer is joined to an outer-mold-line layer.

A decorative optical element that has an appearance of a glass optical element includes an optically transparent body having a faceted globular portion defined by a solid volume of polymeric material. A luminaire, such as for a street light, employs the decorative optical element and an LED circuit board mounted to the circuit board.

A mandrel assembly is configured to receive one or more layers of composite material to form a component. The mandrel assembly may include a tower having an outer forming wall surrounding a central passage, and an upper ring removably secured to the tower. The upper ring is configured to be removed from the tower after the layer(s) of composite material are wrapped around the outer forming wall and at least a portion of the upper ring. The component is removed from the tower after the upper ring is removed from the tower.

The curing press for a tire blank includes a frame and a plurality of circumferentially distributed segments which are capable of forming a tread for the tire. Each of the segments has at least one opening. For each segment, at least one tie rod is mounted slidably and rotatably in the opening of the segment on the one hand and hinged to the frame on the other hand. The mounting and hinging form the only connections of the tie rod to elements of the press other than the tie rod.

A method of manufacturing a self-supporting, monolithic fuselage body, including engaging peripheral mandrel sections around at least one central mandrel section, placing uncured composite material on the mold surface, curing the composite material on the mold surface, and sliding the central mandrel section(s) out of engagement with the peripheral mandrel sections and disengaging the peripheral mandrel sections from the cured composite material without collapsing the mandrel sections. The peripheral mandrel sections each include a shape-retaining core of a thermally insulating material and an outer layer on an outer surface of the shape-retaining core. The outer layer has a coefficient of thermal expansion within the range of variation of that of the coefficient of thermal expansion of the composite material. A mandrel for layup and cure of a predetermined composite material in the manufacture of a monolithic fuselage is also discussed.

An embodiment of a device is described. The device may include a body. The body includes an outer surface and an inner surface defining a bore within the body. The inner surface defines a maximum inner dimension of the bore no more than 10 millimeters. The bore has a longitudinal axis therethrough. The device may include a plurality of parting lines on the inner surface of the body. The device may include a recess in the inner surface of the body. The recess may be a housed recess and may have a depth in a lateral direction perpendicular to the longitudinal axis of the bore.

An injection tooling is configured to inject a polymer resin into a fiber preform for fabricating a part in the form of a body of revolution out of composite material, the part having an internal cavity with back-draft. In order to enable the part to be unmolded after the polymer resin has been injected and polymerized, the tooling includes, arranged at least in the internal cavity, firstly a sectorized ring made up of at least three mutually touching inserts including one forming a keystone, the ring having an outside surface that matches the internal cavity with back-draft and an inside surface that presents natural draft, and secondly a conical drum secured to the inside surface of the sectorized ring to support it and that is withdrawn, once separated from the sectorized ring, relying on the natural draft created by the inside surface of the sectorized ring.
