The present invention relates to a method of manufacturing a plurality of wind turbine blades. The method comprises first, second and third stationary moulds (64a, 64b, 64c), moulding respective first upper and lower shell halves (74a, 76a), removing and turning the first upper shell half (74a), and positioning and bonding it on the first lower shell half (76a) to form a closed wind turbine blade shell. This is repeated for continuously manufacturing a plurality of wind turbine blades.

A method is described of making a training firearm that has a replaceable magazine. The training firearm is not an actual firearm but possesses a visual look and tactile fee of an actual firearm, to enable a user to train realistically but safely.

A performance in a technique using a heater for manufacturing a resin molding product is further improved. A method of manufacturing a resin molding product includes: a step of placing a first portion configuring a resin molding product, in a first mold; a step of placing a second portion configuring a resin molding product, in a second mold; a step of inserting a heater between the first mold and the second mold; a step of partially heating the first portion and the second portion by the heater; a step of evacuating the heater; a step of welding the first portion and the second portion; and a step of extracting the resin molding product including the first portion and the second portion.

A molding die includes a resistance heating element included in a surface portion of the molding die and configured to heat a molding surface by generating heat, and a heat insulator provided further inside the molding die than the resistance heating element and configured to restrain the heat of the surface portion of the molding die from being transmitted to an inside of the molding die. The surface portion of the molding die includes the molding surface.

A method is described of making a training firearm that has a replaceable magazine. The training firearm is not an actual firearm but possesses a visual look and tactile fee of an actual firearm, to enable a user to train realistically but safely.

A method of producing an assembled product includes a first step of clamping a mold including a first unit and a second unit, a second step of forming the plurality of parts by injecting molten resin into each of a plurality of cavities, a third step of opening the mold, and a fourth step of respectively opposing the plurality of parts held by the first unit in the third step to corresponding assembling portions of the second unit. The first through fourth steps are repetitively performed, and in the first step, the plurality of parts held by the first unit are supplied to the corresponding assembling portions, and the plurality of cavities are defined by first forming portions of the first unit and second forming portions of the second unit.

Composite structures and methods of forming composite structures are provided. The composite structures can include one or more composite structure components. Each composite structure component is formed from a composite panel that includes one or more sheets of material. The sheets of material include a thermoplastic material and a plurality of reinforcing fibers. A composite panel can be formed in three dimensions to form a composite structure component. Multiple composite structure components can be fused to one another to form a composite structure. In addition, each composite structure component and the composite structure formed therefrom can include an aperture. An interior volume can be formed between adjacent composite structure components. Methods for forming a composite structure can include a step of simultaneously molding and fusing composite structure components.

A multifunctional fully integral panel system design, a unique material configuration, and a process for fabricating a net shape (or nearly net shape) panel in one production cycle. The panel may comprise a base facing with an outer perimeter, a decorative film applied to the exterior of the base facing, an aft facing having an outer perimeter fused to the base facing, and a reinforcement core disposed between the unfused portions of the base and aft facings, which reinforcement core also acts as acoustic insulation (i.e., a noise attenuator). Alternatively or additionally, a foam core or blanket having thermal and/or acoustic insulation properties is attached to the external surface of the aft facing. The fabrication process involves the application of different heat treatments to panel components having different forming temperature or rubbery/elastic plateaus.

A method for producing a plastic container from a first plastic half-shell and a second plastic half-shell, with a first attachment permanently fastened to the first plastic half-shell.

The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.
