A method for producing a conditioning element, in particular for electrical energy storage devices, includes providing at least one channel element; and molding a structure onto the at least one channel element, at least in areas or sections.

The invention relates to a plastics connecting seam for the fluid-tight connection of at least two plastics surfaces. The plastics connecting seam is in the form of a plastics connecting seam that supports strength under a load in such a way that a load acting in a standard load direction increases the connection strength of the seam.

The invention relates to a method for producing an injection-molded part, the injection-molded part being a plastic cylinder for a needle-free syringe. The cylinder has an opening. The invention further relates to an injection-molding tool for producing the cylinder, the injection molded tool including an outer mold component and an inner mold component, which together define a clearance which determine the injection-molded part and the cylinder. The outer mold component and the inner mold component are designed such that the clearance is formed without an obstacle for plastic between the outer mold component and the inner mold component.

A method of manufacturing a door skin and a fuselage wall having a doorway and a member extending into the doorway for abutting the door includes placing a first sheet of uncured composite material on a mold plate to define the door and fuselage skin, disposing an insert over the first sheet overlapping a desired periphery of the door, placing a second sheet of uncured composite material on a peripheral portion of the insert and over the first sheet adjacent the peripheral portion of the insert to form the member, curing the sheets and bonding the sheets together adjacent the insert during the cure, removing the insert from between the sheets after cure, and separating the door skin from the wall skin after cure by moving a cutting tool through the first sheet and without penetrating the second sheet around the desired periphery of the door. An assembly for manufacturing the door skin and a fuselage wall is also discussed.

A structure for use in a compressible resilient pad. The structure contains both axially elastomeric strands and relatively inelastic strands co-extruded in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

A method of forming an elongated composite element includes providing an elongated tubular member and establishing a plurality of holes through an outer wall of the elongated tubular member. A polymeric resin is provided that comprises a curable material that, when uncured, comprises a fluid material and that, when cured, comprises a substantially rigid material. The uncured polymeric resin is extruded along the elongated tubular member, whereby the polymeric resin flows at least partially through the holes and is disposed within the inner cavity and at an outer surface of the outer wall of the elongated tubular member. The polymeric resin is cured to form the composite element whereby the cured polymeric resin limits flexing of the at least one elongated tubular member and the elongated composite element.

An anti-graffiti window film covering system that includes multiple polymeric film layers. Each layer includes a unique visual indicia to identify the number of sheets remaining in the system.

In one example, a method includes positioning a tool in a mold, forming a parison of melted plastic, closing the mold around the parison and tool such that part of the tool is positioned between a portion of the mold and the parison, creating a blow molded structure by inflating the parison so that the melted plastic comes into contact with an interior portion of the mold and into contact with the tool, and after the mold is closed, operating the tool to form an integral compression molded element within the mold, and a parting line formed by the mold in the blow molded structure forms no part of the integral compression molded element.

A method is described. The method is a continuous manufacturing method of an acoustic transmission loss panel resonator core. The acoustic panel is a double-wall panel construction with two sidewall panels and a resonator core. The resonator core is formed from a roll of film. One or more rollers form interconnected resonator chambers in the film. The resonator chambers are in a rectangular lattice shape. The resonator chambers are continuously formed from a single sheet and then bonded to the second sidewall. The resonator core is then attached between first and second sidewalls. The resonator core defines an air gap between the resonator core and the first sidewall.

A method of manufacturing a part using a cutting machine includes placing a non-porous sheet on a surface of a material cutting machine, removing material from the non-porous sheet to form a plurality of sections of the part, and while the non-porous sheet is present on the material cutting machine, forming fastening holes within the sections. The method further includes removing the sections from a remainder of the sheet, placing the sections together such that each section of the part abuts another section, and inserting fasteners through the fastening holes of the sections.
