A molding method for a synthetic resin molding that includes a molding body, a bent portion, and a flange. The bent portion and the flange are continuous in a longitudinal direction of the side edge. The flange includes a wide portion and a narrow portion. The molding method for the synthetic resin molding includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction, performing injection molding using a colored resin material containing a luster agent kneaded in the material, and forming a protrusion along the side edge in the longitudinal direction at a back of a boundary portion between the flange and the molding body to reduce interference of flow of the molten resin from the flange toward the molding body during the injection molding.

An oriented film includes an orientated semi-aromatic polyester layer and a thermally conductive filler dispersed in the orientated semi-aromatic polyester layer. The thermally conductive filler is at least 20% wt. of the oriented film.

Provided is an object producing method including a powder layer forming step of forming a layer of a powder containing sinterable particles, an object forming liquid applying step of applying an object forming liquid to the layer of the powder to form an object forming region, and a sintering inhibiting liquid applying step of applying a sintering inhibiting liquid to the layer of the powder to form a sintering inhibited region in which sintering of the particles is inhibited, and includes a layer laminating step of sequentially repeating these steps to form a laminate. The object forming region and the sintering inhibited region adjoin each other. The sintering inhibiting liquid contains a first resin. The sintering inhibited region contains the first resin or a second resin derived from the first resin. A predicted amount of a residue calculated by a predetermined method is 800 ppm or greater.

An additively manufactured solid fuel grain for a hybrid rocket engine having a cylindrical shape, defining a center combustion port and comprising a stack of fused layers of polymeric material suitable for hybrid rocket fuel. Each layer is formed as a plurality of fused abutting concentric beads of solidified material arrayed around the center port. An oxidizer is introduced into the solid fuel grain through the center port, with combustion occurring along the exposed surface area of the solid fuel grain center port wall. Each concentric bead possesses a surface pattern that increases the combustion surface area and when stacked forms a rifling pattern of undulations that induces oxidizer-fuel gas axial flow to improve combustion efficiency. The port wall surface pattern persists during the rocket engine's operation as the fuel phase changes from solid to gas and is ablated.

A multi-layer direct blow bottle in which a metallic layer containing a metal pigment having an average thickness of not more than 1 μm dispersed in a resin is formed at a position where it is visible from the outer surface side.

An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m.sup.2/g or more and 10 m.sup.2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.

Aspects of the disclosure are directed to methods and/or apparatuses involving one or more of a conductive polymer, deposition of a conductive polymer and 3D (three-dimensional) printing of a continuous bead of material. As may be implemented in accordance with one or more embodiments characterized herein, a 3D structure is formed as follows. A stacked layer is formed by depositing a continuous bead of material along an uninterrupted path that defines a first layer of the 3D structure. A sidewall of the 3D structure is formed with opposing surfaces respectively defined by successive stacked layers of the 3D structure by, for each stacked layer (including the first layer), depositing the continuous bead of material along the path and with a surface thereof in contact with a surface of the continuous bead of material of an adjacent one of the stacked layers.

A process for manufacturing a urethane foam pad comprising the steps of: providing a urethane resin and a filler agent; mixing a predetermined amount of the filler agent with the urethane resin to create a urethane mixture within a mold container; drawing a vacuum on the urethane mixture; allowing the urethane mixture to expand and gel for a predetermined amount of time to form an expanded urethane foam pad; releasing the vacuum on the urethane mixture; and removing the expanded urethane foam pad from the mold container.

A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings.

The present invention relates to a material composition comprising: (i) a polyester selected from polyethylene terephthalate, polybutylene terephthalate, or mixtures thereof; and (ii) ≥1.0 and ≤30.0 vol % of aluminium particles and to a shaped object comprising a material composition comprising such material composition. Such shaped object does demonstrate the desirable mechanical impact properties, and also demonstrates the desirable electromagnetic shielding, electrical conductivity, and thermal conductivity, given its high loading of aluminium.
