The at least one mold is a mold for placing and shaping a laminated body of fiber sheets which is a material of a fiber reinforced plastic. The at least one pin prevents the fiber sheets from being misaligned by stinging the laminated body of the fiber sheets with the at least one pin. Further, according to one implementation, a preform shaping method for producing a preform includes: placing a laminated body of fiber sheets, which is a material of a fiber reinforced plastic, on at least one mold; shaping the laminated body of the fiber sheets; and preventing the fiber sheets from being misaligned by stinging the laminated body of the fiber sheets with at least one pin.

A system for curing a thermoset composite may include a tooling die configured to receive and support an uncured thermoset composite part and to heat the uncured thermoset composite part; a pressure media bag configured to be placed over the uncured thermoset composite part disposed on the tooling die and including a pressure media; and a mechanical press configured to apply a consolidation pressure to the uncured thermoset composite part disposed on the tooling die, the pressure media bag may be configured to distribute the consolidation pressure applied by the mechanical press to the uncured thermoset composite part disposed on the tooling die.

When a hollow molded body using a preform to be molded with a thin bottom portion is produced while taking advantage of the roughening of the outer surface of an injection core mold, transferred roughening marks are prevented from appearing on the bottom portion of hollow molded bodies, so that the hollow molded body with an aesthetic bottom portion is obtained. An injection core mold (12) has an outer surface of its tip portion corresponding to a preform bottom portion (10) and a lower end portion (14a) of a preform body portion (14). The outer surface corresponding to the preform bottom portion (10) and the lower end portion (14a) of the preform body portion (14) is a mirror-finished surface (20), and the outer surface of the injection core mold for forming the preform other than the mirror-finished surface is a roughened surface (15).

The present application relates to a thermally expandable composition containing at least one peroxide cross-linking polymer, at least one peroxide, at least one polysaccharide and at least one endothermic, chemical blowing agent; as well as to shaped bodies containing said composition and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components using shaped bodies of this type.

A cooling and retaining pin (1) for cooling, by air blowing, and retaining, by air suction, a plastic preform, the pin comprising a body (2), defining a longitudinal axis and having a first opening (5) at a first end thereof, coaxial to said longitudinal axis and adapted to be connected to a handling station; a movable element (3) adapted to slide at least partially inside said body; at least one air passage gap provided at a second end of the body or at said first end; wherein the movable element (3) is adapted to move from a first position, to which a first air passage section corresponds, to a second position, to which a second air passage section corresponds, which is smaller than said first section, so as to adjust a blowing air flow during the cooling step and a suction air flow during the step of retaining the preform.

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 blow molding apparatus is configured to blow mold a preform into a container by supplying a pressurized incompressible fluid into the preform from a pressurized fluid supply unit. The blow molding apparatus includes: a drawing and discharging flow path connected to a drawing orifice; a fluid drawing source to apply drawing force to the drawing and discharging flow path, after blow molding is completed and after and/or while the blow nozzle is moved to a standby position, to draw the incompressible fluid adhering to the blow nozzle; and a pressurized gas supply source to supply a pressurized gas to the drawing and discharging flow path, after blow molding is completed and after a next preform is placed into the mold, to cause the incompressible fluid inside the drawing and discharging flow path to flow out toward the inside of the preform or toward the inside of a container.

In a manufacturing apparatus for manufacturing a resin container which includes an injection molding part configured to injection-mold a preform, a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part, and a blow molding part configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part, the preform is carried into the temperature adjustment part before an outer surface temperature of the preform molded in the injection molding part becomes higher than an inner surface temperature of the preform molded in the injection molding part, and the preform is cooled to be lowered within a range equal to or higher than 10° C. and equal to or lower than 50° C. in the temperature adjustment part.

In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.
