A system and method for the manufacture of wind turbine blade moulds and wind turbine blade mould plugs is described. The method comprises dividing a blade mould geometry (70) or plug geometry into separate geometrical slices or segments. The separate slices can then be used to control a cutting of blank elements (78) to form separate cut surfaces (82). The cut surfaces are used to form a consolidated wind turbine mould surface.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

A part formed by additive manufacturing includes a plurality of layers including a first layer and a second layer, the first layer and the second layer being stacked along a stacking direction, and a work surface formed on an upper surface of the first layer and an upper surface of the second layer. The part also includes a first through-hole formed in the first layer, a second through-hole formed in the second layer, the second through-hole being at least partially aligned with the first through-hole, and a wall extending from the first through-hole to the work surface.

Improvements relating to wind turbine blade manufacture A method of making wind turbine blades of variable length is described. The method involves forming first and second half shells of a main blade section in a main blade mould assembly. A pre-manufactured tip section is selected from a plurality of tip sections of different lengths according to a total length requirement for the wind turbine blade. The tip section is supported adjacent to the main blade mould assembly such that an inboard end of the tip section overlaps with an outboard end of one of the half shells of the main blade section. The main mould assembly is then closed to bond the two main half shells together and to bond the tip section to the main blade half shells. The invention allows blades of different overall length to be produced using a common main blade mould assembly.

Provided is a mold adapted for producing at least a part of a wind turbine blade, including a support and shell fixed to the support for accommodating blade building elements to be embedded in a resin matrix, wherein the shell includes at least one main body shell element and several diverse tip shell elements, which are exchangeably fixable to the support.

Provided is a mold adapted for producing a wind turbine blade, including a first carrier and a shell for accommodating blade building elements to be embedded in a resin matrix for building a blade body part, which shell is placed on the first carrier, and a second carrier changeable in its length and elongating the first carrier adapted to accommodate a prefabricated blade tip to be connected to the blade body part when the blade body part is built.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A core mould element can be mounted between first and second mould parts. The first and second mould parts and the core mould element can be mounted between first and second thermal platens. The thermal platens can have generally planar faces for mounting in a press, for maintaining a desired pressure within the mould assembly. The thermal platens can provide for heating and cooling the mould assembly, and each can include a central portion and end portions, with thermal breaks between the central portion and the end portions. Bores can extend through the central and end portions, for receiving heating elements and pipes for cooling fluid. The end portions can include bores for a cooling fluid for cooling the end portions.

A system cures and manufactures a partially-cured tire assembly. The system includes an annular hub member slid into a corresponding annular, radially inner surface, a plurality of elongate spacer members for maintaining corresponding uniform cavity dimensions by fastening the spacer members to the hub member with flap members thereby enclosing a radially outermost surface of each of the spacer members, a first annular curing platen for axially securing the hub member and spacer members relative to each other, a second annular curing platen for axially securing the hub member and spacer members relative to each other; and a plurality of elongate inserts.
