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 curing press for a tire blank includes a frame and a plurality of circumferentially distributed segments which are capable of forming a tread for the tire. Each of the segments has at least one opening. For each segment, at least one tie rod is mounted slidably and rotatably in the opening of the segment on the one hand and hinged to the frame on the other hand. The mounting and hinging form the only connections of the tie rod to elements of the press other than the tie rod.

Devices, systems, and methods for modular molding of wind turbine blades are provided. Methods of molding wind turbine blades using a modular molding assembly or system and methods of substituting molds are provided. In some embodiments, a modular assembly includes a first base frame and a second base frame hingedly coupled to one another, a first tooling frame disposed on the first base frame, a second tooling frame disposed on the second base frame, a first shell mold coupled to the first tooling frame, and a second shell mold coupled to the second tooling frame. The first shell mold has a first mold surface and a first perimeter and the second shell mold has a second mold surface and a second perimeter. When in an open configuration, the first base frame is coplanar with the second base frame, and, in a closed configuration, the first perimeter contacts the second perimeter.

A blowing mold array includes a blowing mold unit forming a cavity, inside of which plastic preforms are expanded to plastic containers. The blow mold unit includes a blowing mold retainer having at least two mold retainer elements for accommodating parts of the blowing mold unit, and a locking mechanism to arrest at least one part of the blowing mold unit against at least one mold retainer element. The locking mechanism includes an engagement element that can be pivoted and/or shifted relative to a default axis, which in an arrested state abuts a segment of a part of the blowing mold unit. The locking mechanism has an actuating element to loosen the arrest between the mold retaining element and the blowing mold unit. Actuation of the actuating element is coupled with actuation of the engagement element.

The present invention provides a parting locking device configured such that a locking member can be uncoupled from a base holder even with a locking bar inserted in the locking member, and the locking bar stably moves. The locking bar includes a thick-walled and thin-walled portions. In a first state in which the thick-walled portion is located between an engagement element and the inner surface of a bar inserting hole, and in a third state in which the locking bar is pulled out of the locking member, the engagement element is moved to first or second engagement element paths, and the locking member is uncoupled from the base holder. In a second state in which the thin-walled portion is located between the engagement element and the inner surface of the bar inserting hole (9), the engagement element is engaged with engagement recesses, thereby keeping the locking member coupled to the base holder.

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).

A lacrosse head pocket and a related method of manufacture are provided. The pocket can be a molded pocket including individual molded strings, combined strings, shooting strings and support rails extending around a perimeter of the pocket. Certain pocket elements can include transition parts to smoothly transition components having different cross sections. The pocket can include a pre-formed ball channel and hole units having broadsides for connection to a head or other component. The pocket can be attached to a pocket frame, and optionally constructed from a mesh or other synthetic material that is tensioned with the pocket frame. A mold and related molding method are also provided.

An example system is configured to photocure a photocurable material to form a polymer film. The system includes a first chuck configured to support a first substantially planar mold, a second chuck configured to support a second substantially planar mold, and an actuable stage coupled to the first chuck and/or the second chuck. The actuable stage is configured to position the first chuck and/or the second chuck so that the first and second molds are separated by a gap. The system also includes a sensor arrangement for obtaining measurement information indicative of a distance between the first and second molds and/or a pressure between the first and second chucks at each of at least three locations. The system also includes a control module configured control the gap between the first and second molds based on the measurement information.
