Provided is a base (1) for a flexible mold, including: a glass sheet (2); a resin sheet (3); and a bonding layer (4) configured to bond the glass sheet (2) and the resin sheet (3) to each other, wherein the resin sheet (3) protrudes from the glass sheet (2).

A molding compact for forming a transdermal absorption sheet on which a needle-shaped protruding part is arranged is a molding compact that is a laminate of: a first member having a needle-shaped recessed part formed on a front surface thereof, the needle-shaped recessed part being an inverse of the needle-shaped protruding part; a second member provided on a back surface of the first member, the second member being composed of a waterproof and moisture-permeable material; and a third member provided on a back surface of the second member, the third member being composed of a rigid body. Provided are a molding compact that makes it possible to prevent leakage of a drug-containing solution filled into the needle-shaped recessed part, and a manufacturing method for a transdermal absorption sheet using the molding compact.

Methods for forming optical articles with antireflective nanostructured (ARN) surfaces. An aluminum layer is deposited or otherwise applied to the cavity of an injection mold tool. Sequential chemical treatments such as anodization and etching steps form an ARN mold texture on the interior surface of the cavity. The ARN mold texture is a negative of a desired surface texture of the article. During injection molding, the desired ARN surface is thereby produced in the optical article.

Some aspects provide a method of generating a support structure for an object, the support structure and the object to be fabricated via one or more additive fabrication techniques, comprising identifying one or more regions of the object as one or more regions to which mechanical support is to be provided, identifying one or more support points within at least a first region of the one or more regions, and generating the support structure for the object, the support structure comprising one or more support tips coupled to the object at the one or more support points, the support tips being generated based at least in part on a direction normal to the surface of the object at the respective support point.

A rubber article mold capable of discharging air from a molding-surface side to a back-surface side during curing while suppressing the entry of rubber into an air vent hole and a method for producing such a rubber article mold are provided. The rubber article mold includes air discharge means for discharging air from a molding-surface side for molding a rubber article to a back-surface side. The air discharge means is formed as an annular hollow penetrating from a molding surface to a back surface of the rubber article mold. The annular hollow has an inflow area where the air on the molding-surface side flows in, a discharge area for discharging the air having flowed in from the inflow area to the back-surface side, and an intermediate area communicating with the inflow area and the discharge area and smaller or larger in diameter than the inflow area and the discharge area.

The present disclosure generally relates to integrated core-shell investment casting molds that provide an indentation structure corresponding to a thin root component of the turbine blade or vane (i.e. angel wing, skirt, damper lug).

The present disclosure generally relates to integrated core-shell investment casting molds that provide filament structures corresponding to cooling hole patterns in the surface of the turbine blade or stator vane, including in locations that are inaccessible due to the presence of protrusion patterns. The filament structures also provide a leaching pathway for the core portion after metal casting. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.

A device for shaping a workpiece is provided. The device includes at least one first and one second component between which the workpiece to be shaped can be molded under the effect of heat. The design and/or the material properties of the first and/or the second component are selected such that the component's thermal expansion is different in different directions.

According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

A method of manufacturing a part using a cutting machine includes placing a non-porous sheet on a surface of a material cutting machine, removing material from the non-porous sheet to form a plurality of sections of the part, and while the non-porous sheet is present on the material cutting machine, forming fastening holes within the sections. The method further includes removing the sections from a remainder of the sheet, placing the sections together such that each section of the part abuts another section, and inserting fasteners through the fastening holes of the sections.
