A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

A system and method for forming a seal member onto a substrate from a material is disclosed. The system includes a mold comprising an ultraviolet transmissible material, the mold having a first portion and a second portion operatively coupled to the first portion, the first portion having a first cavity, a second cavity, and a channel extending from an outer surface of the mold to the second cavity. The first cavity has a first shape that is complementary to a first side of the substrate and the second cavity has a second shape that is complementary to the seal member. The system also includes an applicator in fluid communication with the channel, where the applicator is configured to provide the material to the second cavity through the channel, and an ultraviolet irradiation device configured to irradiate the mold with ultraviolet light to cure the material when the material is provided to the second cavity, such that the seal member is formed on the substrate.

A plunger gasket with reduced surface contact area including a body, a first side defining a first side surface, a second side defining a second side surface, and at least one surface feature projecting outwardly from at least one of the first or second side surfaces. In example embodiments, at least one surface feature projects outwardly from both the first and second side surfaces. By reducing the surface areas of contact between gaskets during manufacture and processing, the incidence of unintentional cohesion may be reduced or eliminated.

A respiratory protection composite facepiece is disclosed and includes a polymeric rigid facepiece body portion having a first surface and a second surface and a silicone sealing facepiece element chemically bonded at least one of the first surface or the second surface. The first and second surfaces can be opposing major surfaces. A second silicone element is chemically bonded to at least one of the first surface or the second surface. Methods of making the same are also disclosed.

The present disclosure relates generally to the field of medical instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

A film-integrated gasket is provided in which a gasket body is supported by a gasket support body formed of a resin film and a film thickness t.sub.2 at a position where the gasket body is supported is set to be smaller than a film thickness t.sub.1 at an adjacent position thereto so as to satisfy a demand for low reaction force by reducing the compression ratio in the thickness directional in mounting. The film-integrated gasket can be provided with a portion compressed in the thickness direction at the position where the gasket body is supported, so that the portion sets a thickness difference. The film-integrated gasket can alternatively be provided with a portion where a plurality of resin films is stacked at an adjacent position to the position where the gasket main body is supported, so that the portion sets a thickness difference.

A sealing method for sealing an opening of a metallic molded body with a resin molded body, the metallic molded body having a cavity therein and an opening connected to the cavity, includes a step of irradiating laser light onto a joining surface on a periphery of the opening of the metallic molded body in an energy density of 1 MW/cm.sup.2 or more and at an irradiation rate of 2000 mm/sec or more to roughen the surface, and a step of placing, in a mold, a portion including the joining surface of the metallic molded body roughened in the preceding step and sealing the opening with a resin molded body formed by injection molding or compression molding of a resin.

A method of making a sealing article that includes a body and a coating layer disposed on at least one surface of the body. The body comprises a polymeric elastomer such as perfluoroelastomer or fluoroelastomer. The coating layer comprises at least one metal. The sealing article may be a seal, a gasket, an O-ring, a T-ring or any other suitable product. The sealing article is resistant to ultra-violet (UV) light and plasma, and may be used for sealing a semiconductor processing chamber.

A mandrel for a molding process includes a first portion and a second portion that form a mandrel having a channel between the first and second portions. At least one locking pin is configured to urge the first and second portions away from each other to establish a gap in response to inserting the locking pin into the channel along a respective end of the mandrel. A molding apparatus and method of forming a matrix composite component are also disclosed.
