A tool and a method for producing an injection device are disclosed. The injection device comprises a hollow needle which is positioned in a basic body of the injection device. The injection device is produced by a two-stage injection process. At least one first slider and a second slider are provided in a tool block. Together with the tool block, the first slider and the second slider form free space, which defines a shape of a pre-injection molded part of the basic body of the injection device.

A syringe includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The barrel is formed from an injection molding process including aligning a mold die defining an internal shape of the barrel in a molding cavity defining an external shape of the barrel, the molding cavity defined by first and second mold sections. Each mold section includes at least one gate adapted to control the flow of a molding material into the molding cavity. The gates of each mold section are opened to permit the first and second melt streams of molding material to fill the molding cavity surrounding the mold die, where the molding material takes the shape of the molding cavity.

A reusable surgical implement is provided that is formed of a core positioned within an enclosure. The core is formed of a suitable rigid, and optionally flexible material to enable the implant to conform to the desired use for the implement in a surgical procedure. The material forming the enclosure is also stretchable and flexible to accommodate the configuration and/or any flexing of the core, and is biologically inert to enable the implant to be sterilized after use for use in subsequent surgical procedures while protecting the material forming the core. The enclosure can be molded around the core in separate portions or components using multiple molding steps to form an enclosure with the desired attributes.

The invention relates to a method for producing a hollow injection-moulded part, in particular a primary packaging means for medical applications by an injection moulding method, comprising the following method steps: a) Providing a first female die tool having a first mould cavity and a mould core formed as a male die tool; b) Introducing a mould core into the first mould cavity so that a first cavity is formed and the mould core extends beyond the mould cavity in the axial direction (X), thereby bringing the mould core into operative contact with the first female die tool and/or with a receiving member; c) Injecting a first plastic material into the first cavity so that a first portion of the injection-moulded part is formed; d) Transferring the first portion of the injection-moulded part to a second cavity; e) Injecting a second plastic material into the second cavity so that a second portion is formed directly on the first portion of the injection-moulded part.

An injection molding apparatus comprising: an injection molding machine, a heated manifold, a nozzle, the downstream end of the nozzle comprising an inner tubular member having a central flow channel and an outer circumferential surface and an outer tubular member having an inner tubular surface, the outer tubular member forming a seal surrounding the gate, the inner and outer tubular members being adapted to form a sealed circumferential gap, the inner tubular member including one or apertures extending radially through the inner tubular member to route flow radially from the fluid flow channel into the circumferential gap.

A method is provided for producing a fiber-reinforced plastic component, in particular for use in a motor vehicle. The method includes the acts of: providing a blow-molded hollow core, forming the fiber-reinforced plastic component on the hollow core; inserting an end of the hollow core between a first roller and a first counter element, and drawing the hollow core from the plastic component by rotationally driving the first roller.

Provided herein are fluid handling tubes having a cap that includes a sealing member having interior grooves and panels. Also provided herein are fluid handling tubes having a cap that includes (i) a sealing member having a concave surface at a distal region, and (ii) a flat proximal surface. Provided also are fluid handling tubes having a cap that includes an engagement member at an edge of the cap, where the engagement member includes a surface having curvature and a taper. Also provided herein are fluid handling tubes that include a cap comprising a tube sealing member, an anterior engagement member, and one or more channels (e.g., one or more furrows or grooves) between the sealing member and the engagement member that function as a hinge or pivot. Also provided are fluid handling tubes that include (i) a cap having a sealing member that includes an annular protrusion, and (ii) a tube body having an interior surface that includes an annular recess, where the annular recess in the tube body is configured to receive the annular protrusion of the tubular sealing member of the cap.

A two-color molding die includes: a fixed primary die; a fixed secondary die; and a movable die. The fixed primary die includes a first concave portion. The movable die includes a second concave portion facing the first concave portion, and a core pin that protrudes from a base end surface of the second concave portion toward a base end surface of the first concave portion to form a tubular primary molding cavity between the core pin and the first concave portion and the second concave portion. The fixed secondary die includes a third concave portion configured to form a concave secondary molding cavity.

An injection molding die is an injection molding die for molding a resin hollow body including a straight tubular portion having an inner peripheral surface that does not have a tapered portion for die removal. The injection molding die includes a core having a cylindrical portion configured to form the inner peripheral surface of the straight tubular portion. The core has a groove recessed inwardly in the radial direction and formed over a whole circumference of the cylindrical portion in an end portion of the core on a first side in the axial direction, the end portion corresponding to a rear end portion of the resin hollow body in the die-removal direction.

A molding device for manufacturing a plastic hollow part by injection molding includes an injection nozzle and first and second molding stations. Each molding station has a first mold including two mold halves forming, respectively, first and second mold cavities, and a core having a first end, which can be at least partially located inside the first and second mold cavities. A first stripper can be arranged on the core in a passive position, spaced from the first end of the core at a first distance; in a molding position, spaced from the first end of the core at a second distance; and in a demolding position, spaced from the first end of the core at a third distance; wherein the first distance is greater than the second distance, and the second distance is greater than the third distance.
