Disclosed is a method for molding plastic preforms into plastic containers using a blow mould assembly including a blow mould unit, wherein a part of the blow mould unit is retained on a blow mould holder element using negative pressure.

The present invention relates to a manufacturing system (100) and methods for the manufacture of a wind turbine blade, the system comprising a frame body with a lower frame part (92a) and an upper frame part (92b). The upper frame part (92b) is detachably fastened on top of at least part of the lower frame part (92a) of the first frame body (92). A mould body (96) with a main mould part (96a) and a releasable tip mould part (96b) is supported by the frame body. Turning devices are fastened to the lower frame part (92a) for turning the frame body.

A composite component adapted to be formed into an aerofoil, a method of forming an aerofoil, an aerofoil, an aircraft wing and a forming jig. The method involves forming a flat layup sheet of plies (1) to be folded about a central leading edge region (6) of the layup into an aerofoil shape, applying to the flat layup (1) one or more layups of plies (9, 10) shaped as spars, partially curing the layup (1) with the spars attached, folding the resulting partially cured composite component (30) about the leading edge region (6) in a forming jig (19) so that opposing edges (4, 5) of the sheet meet as a trailing edge (36) of the aerofoil (35), clamping the jig (19) closed, and curing the composite component (30) and adhesive in the forming jig (19) to form the finished aerofoil (35).

Tooling assemblies and methods for using a tooling assembly to shape an article are provided. For example, a tooling assembly has a forward end and an aft end and comprises a first tool segment, a second tool segment, a forward cam portion near the forward end, and an aft cam portion near the aft end. The forward cam portion defines a follower surface, and at least a portion of the follower surface has a curvilinear profile. The aft cam portion defines a first surface extending at a first angle and a second surface extending at a second angle. The first and second tool segments define a cavity for shaping an article. An exemplary method comprises positioning an article preform within the cavity and inserting a fastener within the aft end of the tooling assembly until the fastener is fully inserted within the tooling assembly.

A method of manufacturing a mold tool for manufacturing poured foam parts wherein the mold tool includes lower and upper molds and the method includes 3D printing a composite mold to form a mold cavity for forming the poured foam parts. The 3D printing of lower and/or upper molds decreases the time and expense required for producing a mold tool whether for prototype or full production foam parts.

Provided herein is a cell macroencapsulation device composed of hydrogel in a 3D conformation that optimizes encapsulated cell viability and function when transplanted into a vascularized tissue space. The hydrogel macroencapsulation device is intended to reduce or eliminate immune response to the cell graft, while allowing exchange of encapsulated cell-secreted products, such as insulin. Also described herein is an injection-mold and fabrication process to generate the hydrogel macroencapsulation devices for use in the clinic.

The press (1) for curing a green tyre has: a frame (2), at least one plate (4) that is mounted in a sliding manner with respect to the frame and comprises a plurality of pegs (22), a plurality of sectors (8) that are distributed circumferentially around the plate and are able to form all or part of the width of a tread of the tire, and, for each sector, at least one rocker (15) having at least one ramp (19) over which one of the respective pegs is able to pass.
