To form a multilayer plastic lens, a plurality of intermediate layers of a plastic material are injected one after another onto a basic part in an injection molding device in different cavities, wherein at least some of the cavities have a common first runner system with a common material feed. At least its [sic—“one”—“seine” is an obvious typo for “eine” meaning “one”—Tr.Ed.] outer layer consisting of a plastic material is then injected in a cavity by means of a second runner system, the second runner system having a material feed of its own and a control of its own.

A method and system for co-injection molding of two molten plastic materials that allows monitoring and utilization of injection pressure and optionally melt pressure and/or flow front pressure during an injection run. A controller alters the injection pressure so as to achieve and maintain optimal or desired ratios of injection pressure, and optionally melt pressure and/or flow front pressure, of the two molten plastic materials. This allows for more precise part manufacture, including reducing the thickness of a skin or shell layer compared to a core layer of a molded part.

A method for fabricating a lid for attachment to a vessel having an open top surrounded by a peripheral edge portion, includes injection molding from a molten plastic material a first shot structure defining a web portion, a peripheral portion surrounding the web portion; in a second shot procedure, over-molding an elastomeric material different from said plastic material onto the first short structure to form a seal structure portion integrated with the lid portion to form a unitary lid-seal structure, wherein the seal structure portion is permanently adhered to the peripheral portion of the first shot structure, and wherein the seal structure portion is configured to provide an air-tight seal between the lid and a sealing surface portion of the peripheral edge of the vessel when the lid is attached to the vessel.

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.

A lacrosse head pocket includes a plug unit having first and second plugs disposed on a cross lace. The plugs are overmolded by first and/or second runners constructed from a polymeric material so that the plugs are joined with the first and/or second runners. The cross lace extends outwardly from the plug and the overmolded first and/or second runners. Some plug units can have cross laces that cross one another, while other plug units might not include cross laces that cross one another. A method is also provided including: forming a first plug on a first cross lace, placing the first plug in a mold, overmolding a first runner over at least a portion of the plug so the plug and first runner are joined, and optionally overmolding a second plug joined with the cross lace with a second runner or the same first runner.

The present invention is intended to provide a manufacturing method of an insert molded article that makes it possible to manufacture efficiently the insert molded article including a metallic insert, an inside member made of a synthetic resin and covering a portion of the insert, and an outside member made of a synthetic resin different from the material of the inside member and covering a portion of the inside member using general molding machines, not a dedicated two-color molding machine.

General molding machines are used to manufacture the insert molded article formed by injection molding of a resin part in twice. An insert core 7 is used in common in primary molding using a primary molding die C1 and in a secondary molding using a secondary molding die. A round shaft 7C of the insert core 7 is fitted into an internal hole 2C of an insert 2 to form a coupled body 10 in which the insert 2 and the insert core 7 are coupled together. The coupled body 10 is used in common at the primary molding step and the secondary molding step.

An infusion set system, including a base and a fluid connector removably coupleable thereto is disclosed. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

A gasket includes a reinforcing body made of a resin film, a one-side gasket body on one surface of the reinforcing body, and another-side gasket body on another surface of the reinforcing body. The reinforcing body has, between both gasket bodies, a three-dimensional shape in which the resin film is bent. The one-side gasket body includes an inversely-tapered engaging convex portion protruding toward the other-side gasket body, the reinforcing body includes a deformation portion as the three-dimensional shape deforming along a shape of the engaging convex portion, and the other-side gasket body includes an inversely-tapered engaging concave portion embedding therein the engaging convex portion and the deformation portion. At least one of the one-side gasket body and the other-side gasket body includes a flat surface-shaped seal surface, and the reinforcing body has a convex shape as the three-dimensional shape protruding toward the flat surface-shaped seal surface.

A vehicular camera module includes a circuit element and a lens mounting element disposed at the circuit element and optically aligned with an imager of the circuit element. An inner lower pressure polymer molding is formed at least partially over and around the circuit element and the lens mounting element so that the inner molding and the lens mounting element substantially encase the circuit element. A connector element is disposed at an aperture of the inner molding so as to be in electrical contact with the electrical connecting elements of the circuit element. An outer higher pressure injection molded shell is molded over and around the inner molding and part of the lens mounting element so as to encase the inner molding. The outer shell includes a connector portion that generally surrounds the connector element, with the connector element being accessible at the connector portion of the outer shell.

Methods and tools for producing a filled hollow structure, comprising producing an open hollow structure from a first material, providing a closing structure to at least partially close the open hollow structure, filling the hollow structure with a filler medium, and overmoulding the filled hollow structure with a second material as well as hollow structures obtainable by said methods and the use of said tools.
