An apparatus and a technique related to a composite member of two different composite materials is disclosed. Aspects include a technique which may include forming a first portion using a first composite material and forming a second portion molding a second composite material over the first portion. Aspects further include a millable frac or bridge plug may be created.

A seal configuration, mold and manufacturing process that inhibits undesirable elastomer migration onto critical radially inwardly facing portions of a plastic-lined dynamic sealing lip, for improved high-pressure seal operation.

A sealing structure for a front cover of an engine includes a front cover made of resin of an engine in which a through-hole, into which a boss part of a torsional damper is to be inserted, is provided, and a sealing apparatus to seal between the through-hole of the front cover and the shaft part. The sealing apparatus includes a support ring that is made of resin and has an annular shape, and an elastic body part that is made of an elastic material, has an annular shape and is attached to the support ring. The elastic body part has an annular seal lip that contacts the shaft part such that the shaft part is able to slide, and the support ring is bonded to the front cover.

A method for making a valve stem seal, comprising the steps of providing a metal retainer having a top portion and a body portion. The body portion having a first section and a second section. In a first state, the first section of the body portion is cylindrical and the second section of the body portion is cone shaped. Providing a hollow mold. Inserting the metal retainer into the outer mold piece, inserting the inner mold piece into the metal retainer, and then securing the inner and outer mold pieces to each other. Filling a cavity around the top portion of the metal retainer with an elastomeric compound. Removing the metal retainer and the formed rubber sealing element from the mold pieces, and pressing downward over the formed valve stem seal to compress the second section of the body portion radially inwardly.

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.

A sealing strip holder for manipulating and transporting a sealing strip preform in an at least partially automated production process, the sealing strip preform preferably having limp properties. To make the manufacturing process faster and less expensive the sealing strip holder comprises at least one clamping jaw which interlockingly and/or frictionally engages at least one surface portion of the sealing strip preform.

Disclosed is a water resistant joint sealing system comprising a coiled, coated precompressed core material. In one embodiment, the joint sealing system includes a fire retardant material put into the core material. In one embodiment, the fire retardant material forms a layer in, or between portions of material of, the core material.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A system of manufacturing a plurality of components at a location in which the components are used includes a computing device having a software program configured to generate at least one data file for the components and a non-transient memory configured to store the data file. Additionally, the system includes a three-dimensional printing device electrically coupled to the computing device. The three-dimensional printing device is configured to receive the data file and form the components in at least one of an axial plane and a radial plane during a single operation of the printing device.
