Moreover the invention relates to a method of manufacturing such steering wheel.

A method for manufacturing a cellular core for an acoustic panel is provided. The cellular core includes at least one plurality of acoustic cells and a plurality of de-icing channels that extend longitudinally, each de-icing channel being transversely interposed between two successive cells, and the de-icing channels being adapted to channel a de-icing fluid. A manufacturing step includes producing the acoustic cells and the de-icing channels as a single piece such that the cellular core manufactured during the manufacturing step forms a monolithic part.

A preform molding system is disclosed that includes a cavity half that is mountable to a stationary platen of an injection molding machine and a core half that is mountable to a moving platen of the injection molding machine. The preform molding system includes a mold stack assembly having a cavity portion and a core portion. The cavity portion is coupled to the cavity half and includes a cavity insert, and the core portion is coupled to the core half and includes a core insert, a pair of neck rings, and a stripper ring. The core insert has an undercut that defines an annular protrusion on an internal surface of a preform that is created in the mold stack assembly. The preform molding system is configured to permit in sequence, retraction of the pair of neck rings away from the core insert and ejection of the preform from the core insert via the stripper ring.

An injection molding die includes a fixed die and a movable die that move in a die opening/closing direction relatively to each other. A cavity that is formed between the fixed die and the movable die in a die clamping state includes a lateral cavity portion that extends along the die opening/closing direction and a first orthogonal direction. The injection molding die includes a demolding core and a following core that define an end portion of the lateral cavity portion across the fixed die and the movable die in a second orthogonal direction. The demolding core and the following core are configured to be movable in the second orthogonal direction while defining the end portion of the lateral cavity portion across the fixed die and the movable die in the die clamping state, and to be engaged with the fixed die with substantially no play in the second orthogonal direction.

It is an object of the present invention to provide improved methods and compositions for manufacture and use of lateral flow test devices. In particular, the present invention provides a molding method which provides one or more features in the housing base configured to retain the test strip within the base. These features are provided as undercuts in the housing base. The test strip is configured as a bibulous lateral flow material disposed on a substantially non-compressible base layer, and the base layer is positioned within the undercut in order to retain the test strip in the housing base. Optionally, one or more features in the housing base which create the undercut are configured to engage the bibulous lateral flow material by compression and/or friction, thereby increasing the ability of the base to maintaining the test strip in its proper position within the device.

A preform molding system is disclosed that includes a cavity half that is mountable to a stationary platen of an injection molding machine and a core half that is mountable to a moving platen of the injection molding machine. The preform molding system includes a mold stack assembly having a cavity portion and a core portion. The cavity portion is coupled to the cavity half and includes a cavity insert, and the core portion is coupled to the core half and includes a core insert, a pair of neck rings, and a stripper ring. The core insert has an undercut that defines an annular protrusion on an internal surface of a preform that is created in the mold stack assembly. The preform molding system is configured to permit in sequence, retraction of the pair of neck rings away from the core insert and ejection of the preform from the core insert via the stripper ring.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.

What is presented is a method of forming a closure with a sealing gasket in an injection molding machine that has a center rotating cube. The center rotating cube comprises a plurality of mold back halves each comprising cores and a thread unscrewing mechanism. Each core is shaped to form a closure that has a thread and an anti-rotation feature. The method comprises the steps of forming a closure with a through hole, rotating the core to create a gap between the formed closure and the core, and injecting a compressible material through the through hole and into the gap to form a sealing gasket.

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.
