A tire vulcanizing mold comprises a sidewall ring for molding a sidewall portion of a tire. The sidewall ring is composed of a main body provided with a circumferentially extending groove, and mold pieces mounted in the groove so as to be adjacent to each other in the circumferential direction. Between the mold pieces and/or between the main body and the mold pieces, there are formed micro-gaps for discharging gas existing in the tire vulcanizing mold so as to communicate with exhaust flow paths extending from the groove toward the outside of the mold.

The invention relates to a method for manufacturing a turbine engine blade from a preform (10) of composite material polymerised in a mould comprising a lower part (16) and an upper part, comprising at least one closure step, during which the upper part of said mould is placed on the lower part (16) of the mould containing the preform (10). The method comprises, prior to said closure step, at least one sub-step of inserting a position marker (28) into the preform (10), at least one sub-step of compacting the preform using an insert (34) intended to be received in the upper part of the mould (18), and at least one sub-step of checking the position of the marker (28) relative to a reference mark (30) of said insert (34).

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.

A web packaging machine for forming a food product package from a lower web of packaging material and an upper web of packaging material includes a frame, a die member supported by the frame and configured to form or close the food product package, and a clamping device comprising a first end that is pivotally coupled to the frame and an opposite, second end that is configured to secure the die member to the frame. The clamping device is pivotable into and between a locked position in which the clamping device clamps the die member to the frame and an unlocked position in which the clamping device is pivoted away from the die member such that the die member can be moved relative to the frame.

The invention provides a wind turbine blade body manufacturing method, the method comprising the steps of: providing a mould (40) having an elongated mould surface (43), placing a movable insert (50) on the mould surface, in a first position, forming, with the insert in the first position, a first blade body having a first length (L1), placing the insert (50) on the mould surface, in a second position, and forming, with the insert in the second position, a second blade body having a second length (L2) which is different from the first length.

An imprinting apparatus includes a first conveyer unit, a flexible imprinting mold film and a driving roller set. The first conveyer is adapted to convey a workpiece to a working region of the imprinting apparatus. The flexible imprinting mold film has imprinting segments. At least one of the imprinting segments is located in the working region. The workpiece is adapted to be imprinted in the working region through the corresponding imprinting segment. The flexible imprinting mold film is partially rolled around the driving roller set, the imprinting segment located in the working region is expanded from the driving roller set, and the driving roller set is adapted to drive the flexible imprinting mold film, such that at least another one of the imprinting segments rolled around the driving roller set is expanded from the driving roller set and moved to the working region. Besides, an imprinting method is also provided.

A molding die has a lower holder, an intermediate holder, an upper holder, a lock member, an upper link bar, a lower link bar, a restriction member, and a drive part. A movement of the lock member in a molding die opening direction or a molding die closing direction is restricted by the intermediate holder. The upper link bar has a first retaining groove in which the lock member fits when being located at a molding die closing position. The lower link bar has a second retaining groove in which the lock member fits and a release portion that enables the lock member to be released from the first retaining groove. The restriction member is movable between a restriction position that prevents the lock member from fitting in the second retaining groove and a free position that enables the lock member to fit in the second retaining groove.

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.

Assemblies and methods for fabricating one or more molded tire treads are provided along with systems for manufacturing a plurality of tread mold configurations from interchangeable elements.

The present invention discloses a method of manufacturing integrated modular structure using a rotomolding process. The method comprises preparing at least a pair of molds embedded with at least one electric harness, wherein the pair of molds having a base mold and a first mold joined to form an enclosure, filling a first material in the base mold of the pair of molds, providing a heating and cooling cycle, wherein during heating at least the pair of molds being rotated for evenly spreading the molten first material and embedding the electric harness in the molten first material, obtaining a first molded part yielded by at least the pair of molds, and obtaining a second molded part yielded by at least a pair of molds, thereby the first molded part, the second molded part and the at least one embedded electric harness together forming the integrated modular structure.
