The present invention relates to an integrally blow-moulded bag-in-container (2) having an integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner (11) and outer layers (12). It also concerns a preform (1, 1) for blow-moulding a bag-in-container, having an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. The inner and outer layers are of the same material.

A fiber optic cable and connector assembly including a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including a stub fiber supported within a ferrule. The stub fiber is fusion spliced to an optical fiber of the fiber optic cable at a location within the fiber optic connector.

A manufacturing apparatus for manufacturing a resin container, the manufacturing apparatus includes an injection molding part, a temperature adjustment part, a blow molding part, a take-out part, and a rotation plate. The temperature adjustment part includes a first temperature adjustment mold into which the preform is inserted, the first temperature adjustment mold being configured to cool the preform from an outer surface of the preform, a second temperature adjustment mold into which the preform is inserted, the second temperature adjustment mold being configured to cool the preform from an inner surface of the preform, and wherein, in the temperature adjustment part, the preform is cooled so that at least the outer surface temperature of the preform is lowered within a temperature range from 10? C. to 50? C. as compared to the outer surface temperature of the preform when the preform is carried into the temperature adjustment part.

An integrally blow-moulded bag-in-container has as integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner and outer layers. A preform for blow-moulding a bag-in-container has an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. The inner and outer layers are of the same material.

A system for manufacturing a thermoplastic part from a blank part having a first moulding member and a second moulding member which are configured to cooperate together. A first heating body configured to heat the first moulding member and conductively heat the blank part. Two thermal insulation members are configured to cooperatively define a closed cavity in which at least the moulding members and the first heating body are arranged. A casing defining an internal volume in which at least the moulding members, the first heating body and the thermal insulation members are arranged, and a suction member is configured to lower the internal pressure in the internal volume to compress the preform part between the moulding members.

A carbon-fiber product forming device is disclosed. The device includes a first chamber forming with a hollow cavity, a hot-pressing plate disposed inside the hollow cavity, a mold disposed on the hot-pressing plate and formed with an outward opening, an air bag disposed inside a mold cavity of the mold, provided with a bag opening disposed near the outward opening, and attached on an outer surface thereof with carbon-fiber composites, a second chamber mounted on one side surface of the first chamber and disposed on wall surface with an air extracting port, an air inlet port, a heat medium entry port, and a barometric port, and a plurality of barometric pipes included inside the second chamber. Two ends of each of the barometric pipes are connected to the barometric port and the outward opening, respectively, such that the air bag could be periodically injected with air. A heat medium is injected into the inside of the hot-pressing plate when the air inside the hollow cavity is extracted by a vacuum pump via the air extracting port. The accordingly made carbon-fiber product has residual-air-removing rate of preferably above 99% and structural strength improvement of at least 5%.

A fabric coated or impregnated with an elastomeric material may include a polyurethane dispersion layer combined with a sealant. The fabric may be applied in such a fashion so as to enable the elimination of solvent or fluid that is associated with the elastomer. The polyurethane dispersion layer generally comprises an elastomeric material dispersed or dissolved in a liquid medium, such as, but not limited to, water. At the same time, the integrity of the elastomeric composite which is formed from the dispersion and sealant layers may be maintained in order to minimize the presence of air voids and pockets. It has thus been realized that in doing so the performance of the self-sealing volume is dramatically improved. This method of construction usually may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume.

A method of moulding (10; 20) and apparatus (108; 208; 308) therefor, in which a workpiece (100) is preheated and/or post-cooled before and/or after a moulding process, allowing optimal use of the tool for high precision moulding operations.

A manufacturing method includes an injection molding process of injection-molding a preform, a temperature adjustment process of temperature-adjusting the preform while cooling the preform, and a blow molding process of blow-molding the temperature-adjusted preform to manufacture a resin container. In the injection molding process, a step portion thicker than at least an engagement groove of a neck portion is formed between the neck portion and a body portion of the preform.

A method for producing a three-dimensional preform from reinforcing fibers for producing a component from a fiber-reinforced plastic comprises the steps of introducing at least one layer of fibers having a binder into a draping mold, forming the at least one layer of fibers by at least one forming element which is displaceable along the draping mold, applying an airtight film to the at least one layer of fibers during or directly after the forming, creating a negative pressure in the intermediate space between the airtight film and the draping mold, activating the binder and removing the negative pressure after curing of the binder.
