The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

A device for producing microstructures, particularly microneedles and more particularly microneedle arrays, including a female mold that has, on a top side, at least one in particular conical depressed portion for producing a microstructure. The female mold is, for example, in the form of a silicone cap and is connected to a hollow cylinder in particular via a holding element. A plunger is disposed movably inside the hollow cylinder.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

The invention relates to a method for producing a threaded bolt. A blank is introduced into a threaded-bolt negative mold. The blank has a bolt-shaped portion. Fibers which are aligned in the longitudinal direction of the bolt-shaped portion are embedded in a plastics material in the blank. Pressure is exerted on the blank in order to deform the blank in the negative mold such that a threaded structure is formed on a circumferential face of the bolt-shaped portion. The invention moreover relates to a threaded bolt which is manufacturable by this method, and to a system which is conceived for carrying out the method. Lightweight and hard-wearing threaded bolts may be manufactured by the method according to the invention.

A component with a customized exterior surface and a method and tool for manufacturing the same are provided. The component may be formed via a plastic forming process with a forming tool, such that it has a surface texture formed on its exterior surface. The forming tool has at least one tool surface, which defines a mold cavity. The tool surface has a textured layer coupled thereto, such that the textured layer directly contacts a moldable material supplied to the mold cavity. The textured layer has a surface texture formed thereon resulting in the surface texture present on the textured layer being transferred to and formed on the exterior surface of the component during forming. The textured layer may be changeable or replaceable with respect to the at least one tool surface, such that a single tool may form components with different surface textures formed on the exterior surface thereof.

A method of making a light sensor module includes connecting a light sensing circuit to an interconnect on a substrate, and forming a cap. The cap is formed by producing a cap substrate from material opaque to light to have an opening formed therein, placing the cap substrate top-face down, dispensing a light transmissible material into the opening, compressing the light transmissible material using a hot tool to thereby cause the light transmissible material to fully flow into the opening to form at a light transmissible aperture, and placing the cap substrate into a curing environment. A bonding material is dispensed onto the substrate. The cap is picked up and placed onto the substrate positioned such that the light transmissible aperture is aligned with the light sensing circuit, with the bonding material bonding the cap to the substrate to thereby form the light sensor module.

A solid dose for insertion into the skin of a patient wherein the solid dose has a hollow core. There is also provided a solid dose carrier, a device, a method of manufacturing the solid dose and a method of delivering a solid dose transdermally to a human or animal.

The invention concerns in particular a device for moulding an article in which the article is obtained by compression moulding a dose (14) of material in the molten state and comprises at least one orifice (23) after the compression moulding operation, said device comprising at least one die (10), one mandrel (11) cooperating with said die (10) to effect the operation of compression moulding of the dose and one orifice rod (12) sliding in said die (10), said device further comprising a shape endpiece (13) placed between the mandrel (11) and the orifice rod (12) to form the orifice (23) of the article.
