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 medical syringe barrel and a manufacturing method for producing the same can be completed as a molded article by injection molding of a synthetic resin material without requiring post processing like polishing and can fill and administer a predetermined amount of the internal-use solution accurately. A medical syringe barrel includes a tubular barrel section for accommodating an internal-use solution in the interior thereof, an injection nozzle section formed at one end of the barrel section, and a flange section formed at an opening section on the other end of the barrel section to project radially outward. A surface of the flange section has a recess portion, and a weld line which is potentially formed by injection molding is not formed in the internal-use solution filled section.

A pencil for applying a coloring and/or cosmetic substance, having a pigment core composed of the substance that is to be applied and a one-piece injection-molded casing encompassing the pigment core that is composed of a thermoplastic material that consists of a mix of a first plastic and a second plastic, wherein the casing, respectively viewed in the radial direction, has an outer enrichment zone with a higher concentration of the first plastic than in the middle region and the casing, respectively viewed in the radial direction, has an inner enrichment zone with a higher concentration of the first plastic than in the middle region.

An electric connecting structure is provided, which includes an outer casing, at least two electrical connection terminals, at least two cables, and an electronic component. At least part of each electrical connection terminal is fixed in the outer casing. Each of the at least two cables has an end connected to the corresponding electrical connection terminal. The electric connection structure further includes at least one cable holder molded onto the at least two cables and mounted in the outer casing. The electronic component is connected between the ends of the at least two cables. The electric connection structure can simplify the wiring operations and consequently reduce the time and costs required for the wiring operations.

A method of forming a resilient seal about a work piece is presented. The method includes the steps of providing a work piece defining a rib circumferentially protruding from an outer surface about a longitudinal axis of the work piece and providing a mold. The mold defines a first cavity configured to receive the work piece, a second cavity circumferentially extending about the longitudinal axis of the work piece and in communication with the first cavity, and a port in communication with the second cavity. The method further includes the steps of inserting the work piece within the first cavity such the rib is circumferentially in intimate contact with an inner surface of the first cavity, introducing a curable resilient material into the port, thereby filling the second cavity with the resilient material, curing the resilient material, and then removing the work piece from the mold.

The invention provides a dome cover, a camera device, an injection molding die, and an injection molding method in which generation of a weldline is suppressed and deterioration of an acquired image is suppressed. In one aspect of the invention, a dome cover is a dome cover that covers a camera. The dome cover includes a curved section having a curved shape and a skirt section having a cylinder shape and has a top section at the curved section and an opening end section at the skirt section. The thickness of the dome cover is largest at the top section and smallest at the opening end section, and continuously decreases from the top section toward the opening end section. The inner diameter and the outer diameter of the dome cover continuously increase from the top section toward the opening end section.

The invention concerns a connector (1) for fluid transfer circuits comprising a main body (2) including: a first end (2a) equipped with at least one connecting end-piece (3) shaped to cooperate with an element such as an injector, a second end (2b) comprising a gasket bearing area (Z1) intended to house a sealing gasket (101), said connector (1) further comprising a flange (4) added onto the main body (2), preferably at the second end (2b) of the main body (2).

Aspects of the embodiments are directed to an optical component with at least one substantially flat surface. The flat surface can be used as a surface onto which a pick and place tool can contact the optical component for assembly. The optical component can be formed from a mold that includes an insertable pin. For example, the mold can include a three-piece mold: a core and a cavity can be brought together to define a negative space conforming to a shape of the optical component. The core and the cavity, when brought together, also define an opening. The opening can have a shape that conforms to a desired cross-sectional shape of the flat surface of the optical component. An insertable pin, with a substantially flat end surface, can be inserted through the opening during the mold process to form the substantially flat surface.
