The molding element has a molding surface for forming a contact face of the contacting elements and a groove forming rib portion for forming the groove. The groove forming rib portion has opposed rib side faces for forming opposed groove side faces and a rib top face connecting the rib side faces for forming a groove bottom. The groove forming rib portion provides at least one space opening to at least one of the rib side faces and/or to the rib top face and an insert is received in the space. The insert is composed of a plurality of thin plates stacked in a direction along which the rib extends and comprises at least one notched plate of thickness t1 including at least one notch for forming a flexible fence of the closing device; and comprises at least one support plate of thickness t2 without notch.

A contact lens mold part and a contact lens mold assembly (1) are provided. The contact lens mold assembly includes a first mold part (2) and a second mold part (3) assembled together. Each mold part has a lens-forming surface with a circumferential edge, a stop surface extending from the circumferential edge, an intermediate region extending from the stop surface, and an alignment surface extending from the intermediate region. The mold parts can be made to fit together with an interference fit. A method of making a contact lens using the contact lens mold assembly is also provided.

This disclosure relates to the manufacturing of a leading edge section with hybrid laminar flow control for an aircraft. A manufacturing method involves: providing an outer hood, a plurality of elongated modules, first and second C-shaped profiles having comprising cavities, and an inner mandrel; assembling an injection moulding tool by placing each profile on each end of the inner mandrel, arranging a first extreme of each elongated module in one cavity of the first profile and a second extreme of the module in another cavity of the second profile, both cavities positioned in the same radial direction; and placing the hood on first and second profiles to close the tool. Further, the injection moulding tool is closed and filled with an injection compound comprising thermoplastic and short-fiber. Finally, the compound is hardened and demoulded.

The present invention relates to a wind turbine blade mould comprising a first mould part and a second mould part, where said first mould surface is configured for moulding a pressure side shell of a wind turbine blade, where said second mould surface is configured for moulding a suction side shell of a wind turbine blade, and where the wind turbine blade mould and thus also a wind turbine blade moulded in said mould comprise a first end, a second end, a pressure side shell, a suction side shell, and further comprise a leading edge area and a trailing edge area. The present invention also relates to a wind turbine blade and a manufacturing method for producing a wind turbine blade using a wind turbine mould as mentioned above.

Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

An apparatus and process for forming material, the apparatus or process comprising at least one forming unit, each said forming unit having at least one forming opening to receive a feed of material to be formed, the at least one of said forming opening(s) comprises opposing or at least one forming surfaces, at least one of said opposing forming surfaces being dynamically controllable into a pre-determined shape or profile to impart a resultant shape or profile of a pre-determined formation upon the feed of material passing through said forming opening of a said forming unit.

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.

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 molding system for applying insulation to a pipe employs an elongate mold in which to receive the pipe. A mold adjustment mechanism can adjust a shape of the mold to correspond to a shape of the pipe as the pipe sags in the mold cavity. In a method of insulating the pipe, the shape of the mold is adjusted to correspond to the shape of the sagging pipe and curable material is imparted into the mold while maintaining the adjusted shape of the mold. The elongate mold can include at least one double-walled mold member with an inner form wall, an outer jacket, and a plurality of radial supports that support the outer jacket on the inner form wall in radially spaced apart relation therewith.
