Two molded articles having a cylindrical two-piece split shape is formed by forming two primary cavities in a desired shape with molds assembled together and injecting a molten primary resin into the two primary cavities. An assist material is injected into a secondary cavity into which a molten secondary resin is injected in a state where the two molded articles are located opposed to each other via a space therebetween and internally fitted into one secondary cavity formed by the molds that are assembled together by shifting the positions. A flange portion having any desired shape is disposed on an outer circumferential surface of a resin pipe in a two-layer structure in which an inner surface layer formed of the cured secondary resin is integrated with an outer surface layer formed of the two molded articles. Thus, a portion having any desired shape is easily manufactured on the resin pipe.

A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve sear and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

A structural reinforcement and biocompatible pump head for a pump includes a reinforcement structure having a plurality of ports and fluid pathways therein. The fluid pathways in the reinforcement may be coated or lined with a biocompatible material to form a biocompatible pump head useful for liquid chromatography and other analytical instrument systems. The biocompatible material may be injection molded into the fluid pathways of the reinforcement structure and may be machined after core pins are removed to obtain a desired surface finish and/or size of the biocompatible fluid pathways of the pump head.

A component assembly includes a workpiece and at least one elastic member. The workpiece defines an axis, and has two ends opposite to each other along the axis, and an axial hole extending through the ends. The at least one elastic member is made of an elastic material and has a ring shape. The at least one elastic member is disposed on and abuts against one of the ends of the workpiece, and surrounds the axial hole.

A catheter has improved position and/or location sensing by using single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are provided on a single axis sensor assembly, which can be linear or nonlinear. The catheter may include a catheter body on which at least one, if not at least three single axis sensors, are mounted serially along a length of the body. In one embodiment, the magnetic-based sensor assembly includes at least one coil member wrapped on the catheter body, wherein the coil member is connected to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system.

A molding system for applying moldable material to a pipe. An elongate mold has at least one elongate mold member movable relative another elongate mold member between open and closed positions. In the closed position, the mold may define an elongate vent between the mold members that extends along the longitudinal axis of the mold. Air in the mold cavity displaced by moldable material received into the mold cavity vents through the elongate vent along the longitudinal axis of the mold. The mold can include a positioner that positions the mold members in the closed position while the mold is filled with the moldable material. The positioner also allows movement of the first mold member toward the open position to partially open the mold as the moldable material cures to reduce forces imparted upon the mold due to expansion of the moldable material during curing.

A faucet main body structure, an injection molding mold and a molding method are provided. A main body inner core is fixed in the injection molding mold by a new fixing method, ensuring that no additional positioning structure is required to be provided on the outer surface of the main body inner core, so that in the case that the main body inner core is subjected to over-molding, a main body injection-molded layer of the main body injection-molded part is enabled to closely attached to the main body inner core without causing gaps therebetween, which ensures that the faucet main body structure is not susceptible to water seepage, and prolongs the service life of the product.

A die for casting junctions of a coating of a pipeline is configured to be coupled to the pipeline to form an annular shaped closed compartment about a tubular joint portion comprising a tubular wall, which extends about a designated axis; a plurality of centering devices configured to align the axis of the tubular wall with a longitudinal axis of the pipeline; two annular walls arranged respectively at the opposite ends of the tubular wall; and two pluralities of vent openings arranged along the tubular wall respectively at each of the annular walls; and at least one feeding port configured to supply polymer material into the closed compartment.

A method for manufacturing a roof rack that is mounted on a roof panel of a vehicle and includes a main body and a hollow profile integrally formed inside the main body may include: manufacturing the hollow profile using a drawing method, wherein the hollow profile is formed of a resin composite and has a hollow portion extending in a lengthwise direction thereof; mounting caps on opposite longitudinal end portions of the hollow profile in the lengthwise direction to seal the hollow portion; inserting the hollow profile having the caps mounted on the opposite longitudinal end portions thereof into an injection mold; and insert-molding the main body having the hollow profile integrally formed inside, by injecting a moldable material to surround the hollow profile.

A catheter is provided with improved position and/or location sensing with the use of single axis sensors that are mounted directly along a length or portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are provided on a single axis sensor (SAS) assembly, which can be linear or nonlinear as needed. A catheter of the present invention thus includes a catheter body and a distal member of a particular 2D or 3D configuration that is provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. In one embodiment, the magnetic-based sensor assembly including at least one coil member that is wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region advantageously provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.
