A method of forming a mold having cavities for molding loop-engageable, hook-shaped fastener elements, includes: supporting a first plate having an outer surface that defines a plane; manipulating a material-cutting beam of a laser along a predetermined curved profile to cut a cavity into the outer surface of the first plate, the predetermined curved profile being generally hook-shaped, the cavity defined by a wall extending into the first plate from the outer surface; in a series of subsequent actions, repeatedly indexing the first plate relative to the laser to direct the material-cutting beam at further positions on the first plate and repeating the step of manipulating the material-cutting beam of the laser relative to the first plate to form a series of cavities, each having a hook-shaped profile; and positioning a second plate adjacent the outer surface of the first plate, the second plate providing a side wall surface for each of the cavities of the first plate, the first plate and the second plate in combination forming a mold having cavities for molding loop-engageable, hook-shaped fastener elements. Various methods for aligning such mold plates in a fastener element molding apparatus are also provided. A hook product includes a stem portion integrally molded with and extending from a sheet-form base to a distal end, the stem portion having a planar side; and a crook portion extending from the distal end of the stem portion to overhang the sheet-form base in an overhang direction, the crook portion having a flat planar side co-planar with the planar side of the stem, and an upper surface extending upward from an upper extent of the planar side of the crook portion to an apex.

A mold assembly for making a tool bracket of a tool suspension device includes a lower part and an upper part. The upper part is mounted on the lower part and includes a common mold and multiple interchangeable molds. The common mold has multiple through cavities to mold the tool brackets simultaneously. Each through cavity has a primary flat molding surface. The interchangeable molds are demountably mounted in common mold and have upper cavities aligned respectively with the through cavities. Each of the upper cavities has a bottom, a marking portion formed on the bottom and a secondary flat molding surface flush with the primary flat molding surface of the aligned through cavity. Consequently, the tool bracket molded by the mold assembly has a front product indicator and an offset parting line to make the front of the tool bracket clean.

A fluid manifold such as an end head for a hydraulic power pack is manufactured by providing at least one piece of tubing into a mold and molding a material to form a block around the tubing, resulting in a manifold block that has tubing arranged inside to form fluid circuitry. Additional conduits and mounting points for componentry such as valves and fittings may be machined into the block in fluid connection with the tubing conduits.

A method for producing a holding element on an edge region of a molded body made of a brittle material. The molded body is placed in a form tool that forms a charge cavity in the edge region of the molded body. The charge cavity is at least partially filled with a plastic material, and the molded body having the holding element formed thereon is then removed from the form tool. According to this invention, in order to optimize the production process, the molded body is held in the form tool by a clamping element. A section of the charge cavity is defined by the clamping element. A sealing element is applied to the molded body in a transition region between the charge cavity and the clamping element. The plastic material is introduced into the charge cavity by extrusion.

This invention relates to a method of preparing a preform for an optical fibre, and more particularly to a method of preparing a preform for a polymer holey optical fibre. The invention provides a method of preparing a preform for manufacture of a polymer holey optical fibre comprising casting a preform body in a mould from a suitable material, said mould including at least one protrusion adapted to form a corresponding hole within the preform, and subsequently separating the preform body and mould. The invention also provides a method of preparing a preform for manufacture of a polymeric holey optical fibre comprising separately casting one or more elements of a preform in respective mould(s) from a suitable material, and separating said elements from said respective mould(s) and combining said elements to construct a preform having a plurality of holes therein, each hole being formed in an element or formed by the combination of two or more elements.

A mold assembly for producing a plurality of contact lenses includes a front curve fixture assembly, a base curve fixture assembly and a plurality of mold cavities. The plurality of mold cavities are defined by a surface on either the front or the base curve fixture assembly and is disposed in a zig-zag manner relative to each other. Each of the plurality of mold cavities includes a retention edge for complimentary engagement with a mold. The retention edge of a first subset of the plurality of mold cavities is spaced apart from a selected fixture mating surface at a first distance and the retention edge of a second subset of the plurality of mold cavities being spaced apart from the selected fixture mating surface at a different second distance so that a plurality of molds may be placed in adjacent cavities so as to overlap the mold flanges.

A method of making a laryngeal airway of the type that includes a respiratory tube and an inflatable positioning shield having a base and an inflatable, hollow peripheral portion is described herein. The method includes introducing at least one molding material onto internal walls of a mold, wherein the mold has a cavity defined by internal walls that conform to the external wall of the laryngeal airway, and wherein only a sufficient amount of the molding material is introduced onto the internal walls of the mold that is necessary to create external walls of the laryngeal airway having a desired thickness and allowing the molding material to cure about the internal walls, thereby forming laryngeal mask.
