An optical resin formed body manufacturing method includes: (i) depressurizing an inside of a container holding a molten optical resin; (ii) pressurizing the inside of the container holding the molten optical resin; and (iii) shaping the optical resin taken out of the container into a given shape. The steps (i) and (ii) are sequentially performed once each or are alternately performed two or more times each. In the step (i), a duration t1 [min] of the depressurization of the inside of the container is set such that the duration t1 and a viscosity .Math.1 [Pa•s] of the molten optical resin satisfy a relation .Math.1/t1 < 200. In the step (ii), a duration t2 [min] of the pressurization of the inside of the container is set such that the duration t2 and a viscosity .Math.2 [Pa•s] of the molten optical resin satisfy a relation .Math.2/t2 < 200.

A method for manufacturing a plastic substrate having excellent thickness uniformity, and a plastic substrate having excellent thickness uniformity manufactured thereby.

A battery case shaping apparatus and method shape a pouch-shaped battery case. The battery case shaping apparatus includes a conductive liquid and positive and negative electrodes each configured to generate electric discharge in the conductive liquid in order to prevent a laminate sheet for battery cases from being damaged by friction between a punch and a die and to allow the entirety of the laminate sheet to be elongated.

An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.

Systems and methods are provided for utilizing pellet-loaded bladders to consolidate and/or harden composite parts. One embodiment is a method for fabricating a composite part. The method includes laying up a preform that is made of fiber reinforced material and that includes a cavity, inserting one or more bladders that are loaded with expandable pellets into the cavity, inflating the bladders in response to a triggering condition, consolidating the preform while the bladders are inflated, deflating the bladders, and removing the bladders from the cavity.

A device for manufacturing a window member includes a chamber, a pressure adjustment pump connected to the chamber and configured to adjust an internal pressure of the chamber, a support configured to support a base substrate, the base substrate having a plurality of trenches of which a lengthwise direction is a first direction and an auxiliary film that surrounds at least a portion of the base substrate, a dispenser configured to provide a soft material to one side of the base substrate, a pressurizer disposed within the chamber and configured to apply pressure to the base substrate as the pressurizer moves, a curing machine configured to generate a protective layer by curing the soft material, and a cutting machine configured to cut at least a portion of the protective layer.

A mold core for producing a component of fiber composite material with a cavity. The mold core makes a particularly simple and efficient demolding process possible by a mold core extending along a longitudinal axis and which is in the form of a hybrid core and which includes, viewed in a cross section perpendicular to the longitudinal axis, a first core portion and a second core portion, wherein the first core portion is formed from a first material with high stiffness and low coefficient of thermal expansion, and wherein the second core portion is formed from a second material that differs from the first material, and is configured such that, under predetermined conditions, its form changes in a predetermined manner such that removal of the mold core from a cavity in the cured component is made easier.

Methods and apparatuses for mounting a material (1) on a carrier (6) are provided. To this end, the material is arranged on a porous layer (2) of an air bearing arrangement (2, 3).

A composite material molded product has a hollow portion, a bent portion, or a curved portion in a transverse section thereof. When the composite material molded product has, for example, a bent portion, a surface on an inside of the bent portion is a pressed surface. A mold includes a pressing body that is thermally expandable and has an outer surface shape corresponding to a shape of a pressed surface, and a mold main body including a cavity accommodating the laminate and the pressing body inside, the cavity including an inner surface shape corresponding to a shape other than the pressed surface. The cavity is sealed in a state that the pressing body is disposed in the cavity. The laminate is accommodated in a molding space formed between an inner surface of the cavity and an outer surface of the pressing body.

A method produces a fiber composite component for a motor vehicle. The method provides a semifinished fiber composite blank, wherein the semifinished fiber composite blank includes reinforcing fibers and a matrix material. The semifinished fiber composite blank is arranged between a first membrane and a second membrane. The semifinished fiber composite blank is shaped into a fiber composite molding by pressing the semifinished fiber composite blank together with the first membrane and the second membrane via a pressing device, and the fiber composite molding is consolidated.
