Tools for sealing a tubing in a downhole environment. The tools feature top and bottom slip assemblies and a monolithic sealing element. The monolithic sealing element includes a portion that is disposed between the top and bottom slip assemblies as well as portions that encapsulate the slip assemblies. When the tool is actuated from a run-in configuration to a set configuration, the slips move toward each other squeezing the sealing element so that it forms a fluid-tight seal with the tubing. Teeth of the slip assemblies penetrate the portions of the sealing element disposed thereon and bite into the tubing.

This invention provides a highly reliable separator integrated gasket for fuel cells free from deformation of a separator in a gasket molding process. In order to achieve the object, a pair of separators having adjacent portions approaching each other and separation portions separating from each other in a stacked state and having manifold holes opened in the separation portions are stacked via a spacer in which an inner peripheral hole is opened and which enables the circulation of a fluid in a direction orthogonal to the stacking direction so that the manifold hole and the inner peripheral hole are continuous to each other, a stacked object of the separators and the spacer is disposed in a mold, and then a rubber molding material is charged into and cured in gasket molding cavities defined between a surface opposite to the spacer in the separator and the mold.

A method for manufacturing a sealing device to improve the positioning accuracy of a parting operation while also improving manufacturing efficiency. The method includes molding an elastomeric cylindrical molded body (100a) with a plurality of cylindrical surface portions (130) and a plurality of annular outer peripheral convex portions (110) arranged alternately on an outer peripheral side thereof, and further provided with a plurality of cylindrical surface portions and a plurality of annular inner peripheral convex portions arranged alternately on an inner peripheral side thereof. The cylindrical surface portions on the outer peripheral side and the cylindrical surface portions on the inner peripheral side, as well as the outer peripheral convex portions and the inner peripheral convex portions are provided so as to be at the same positions in the axial direction.

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 apparatus for processing an elongated structure includes a mold within which an uncross-linked rubber material is placed, at least one heating unit configured to heat the mold, and a pressure device configured to press the rubber material using the mold heated by the heating unit to promote shaping the rubber material by the mold while proceeding the cross-linking of the rubber material. The heating unit includes a central heating device configured to heat a longitudinal central portion of the mold, multiple cooling devices configured to cool two longitudinal end portions of the mold, multiple intermediate heating devices configured to heat two intermediate portions between the longitudinal central portion and the longitudinal end portions of the mold, heat shield plates disposed between the central heating device and the intermediate heating devices, and heat shield plates disposed between the cooling devices and the intermediate heating devices.

The present invention relates to a fibre-reinforced 3D-printed elastic product (1, 3, 4, 7, 10, 12), wherein the product comprises a weight proportion of ≥50% of a polymer having a mean molecular weight of ≥5000 g/mol, measured by means of GPC, and a weight proportion of ≥0.5% and ≤20% of one or more fibres having an aspect ratio of ≥100 and a length of ≥3 cm and ≤1000 cm, the product being produced at least in part by means of an FFF (Fused Filament Fabrication) method, and the product having a tensile modulus of ≥1.5 GPa in the region of the fibre reinforcement and in the direction of the fibre symmetry axis. The product also has a tensile modulus, measured according to DIN EN ISO 527-1, of ≤1.2 GPa in the region of the fibre reinforcement and perpendicular to the fibre symmetry axis, and has a yield strength of ≥5%, measured according to DIN EN ISO 527-1, perpendicular to the fibre symmetry axis.

Provided are methods and systems for manufacturing and using heat-shrink elastomeric. An example method of manufacturing a heat-shrink elastomeric element comprises providing a thermoplastic elastomeric element having a first shape; modifying the thermoplastic elastomeric element to produce a thermoset elastomeric element having the first shape; heating the thermoset elastomeric element to a temperature of at least the glass transition temperature of the thermoset elastomeric element; adjusting the first shape of the thermoset elastomeric element to produce a second shape with at least one dimension greater than that of the first shape; and cooling the thermoset elastomeric element to a temperature below that of the glass transition temperature of the thermoset elastomeric element to produce the heat-shrink elastomeric element.

A fitting or connector for use in constructing a tubing assembly is made by bonding an olefin gasket to an end face of a polypropylene fitting member. The gasket is bonded to the fitting member via a heat fusion technique that causes localized melting together of the gasket and the fitting and generates a composite fitting or connector.
