Disclosed is a method for manufacturing a cannula unit with a cannula housing and a cannula, in which a cannula is injection molded onto a molding core pin having an outer diameter d1 to produce a cannula having a distal end with a larger outer diameter than the outer diameter of the remaining cannula, a first distal section adjoining the distal end, a second proximal section adjoining the first distal section, and a proximal end. A cannula housing is injection molded onto the distal end and the first distal section of the cannula and the molding core pin is removed from the cannula. A piercing needle with an outer diameter d4 is threaded into the cannula, wherein the diameter d4 of the piercing needle is chosen such that it is smaller than the diameter d1 of the molding core pin.

A flexible elastomeric grip for a golf club has an elastomeric insert extending fully through the wall of the tubular grip and exposed on its exterior surface. The insert is comprised of a material having greater stiffness than the body material for enhancing gripability.

A catheter manufacturing method includes positioning a shaft in a cavity of a mold. The shaft is an elongated tubular body configured to be inserted into a living body. The mold includes a first mold die and a second mold die that contact one another to define a closed space which is the cavity. The method includes injecting a molding material into the cavity from a gate at a position between the proximal end and the distal end of the shaft in the axial direction. The injecting position is offset from the center of the shaft in the transverse direction. The method includes molding a hub onto the shaft by solidifying the injected molding material in the cavity onto the outer surface of the shaft.

A melt dispenser for plastic molding comprises a barrel unit removably mountable to a drive unit. A feed screw is received within a barrel of the barrel unit and is rotated by the drive unit to dispense molten molding material through an outlet of the barrel. A coupling mechanism can be engaged to hold the barrel unit against the drive unit and on to connect the screw to the drive. The coupling mechanism is operable by an actuator.

A cartridge for a medium to be dispensed includes a head part having a dispensing outlet and a film forming a cartridge wall, with the film bounding a cartridge chamber for the medium to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has a collar, the collar surrounding the dispensing outlet in a radially outer region of the head part and extending in the longitudinal direction. The front end of the film is sealingly and non-releasably connected to the collar of the head part. The collar of the head part has an inner surface extending in the longitudinal direction and includes at least one projection projecting radially inwardly.

A method for manufacturing a stopper for closing a neck of a container comprises a first step of molding the stopper in one piece. The stopper includes a sealing membrane provided with a central opening, a tubular stem centered on an axis and extending from the sealing membrane around the central opening, and a capsule connected, by a tear wall, to a free end of the stem. The capsule is configured to be wedged in the stem to seal the neck of the container. The method comprises a second step in which, while the tear wall is intact, a force, in line with the axis, is applied to the stopper so as to break the tear wall and move the capsule inside the stem until the capsule is wedged in the stem.

A roller shaft is inserted into a mold including molding members respectively having a first mold surface that defines an outer circumference of a roller portion and second and third mold surfaces that respectively define first and second flat portions of the roller portion, and the mold is then closed. A molding material is injected around the roller shaft to integrally mold the roller portion. The roller portion includes the outer circumference and the first and second flat portions rising from the roller shaft to the outer circumference. The roller shaft includes flange portions at portions corresponding to the first and second flat portions. The flange portions prevent the molding material from leaking outside the first and second flat portions when the roller portion is integrally molded around the roller shaft by injection molding.

A thermoplastics injection molding process coats a field joint of a pipeline by positioning a mold tool around the field joint to define a mold cavity. Thermoplastics material injected into the mold cavity forms a field joint coating that will set in the mold cavity. As the thermoplastics material shrinks in the mold cavity while the field joint coating sets, compacting pressure is applied radially inwardly within the mold cavity against a radially outer side of the field joint coating. A compacting fluid introduced into the mold cavity between the mold tool and the field joint coating may be used to apply pressure against the field joint coating. This accelerates and controls cooling of the field joint coating while maximizing quality.

A tubular mesh filter has a first ring-shaped portion formed in one end side of a tubular filter portion that filters out a foreign object from a fluid and a second ring-shaped portion formed in the other end side of the filter portion. The first and second ring-shaped portions are thicker than the filter portion. The first and second ring-shaped portions and the filter portion are injection-molded in an integral manner by initially injecting molten resin into a first cavity portion used to shape the first ring-shaped portion, flowing the molten resin filled in the first cavity portion evenly to a second cavity portion used to shape the filter portion, and supplying the molten resin filled in the second cavity portion to a third cavity portion used to shape the second ring-shaped portion.

According to some exemplary embodiments, the present disclosure is directed to exemplary polypropylene tubes and the methods of making such, including, molding a polypropylene tube with a rounded bottom and an opening, moving the molded polypropylene tube to a secondary position, electrostatically attaching a second shot label to a flat cavity surface opposite the rounded bottom of the molded polypropylene tube, injecting polypropylene through an opening in the mold, and forming a flattened surface on top of the rounded bottom, the flattened surface encompassing and displaying an exterior side of the second shot label.
