A method of injecting a sealing gel into a predetermined structure for a work piece is provided. The method includes the following steps: providing a molding tool with an insertion structure shaped with respect to compliment the predetermined structure, enclosing a local region of a recess of the work piece with the molding tool, injecting a fluid sealing gel into the molding tool, and dismantling the molding tool after the sealing gel has cooled to a solid state.

A method of manufacturing a substrate integrated gasket includes an application step of applying an adhesive agent onto a surface of a substrate with a predetermined pattern which corresponds to an extending shape of the gasket to be formed, and a step of filling an uncured molding material into a cavity defined between the substrate and an inner surface of a metal mold by setting the substrate within the metal mold and mold clamping and curing the uncured molding material. The application step forms an adhesive agent main application area of the adhesive agent extending along an extending direction of the cavity, an adhesive agent partial application area coming into close contact with the metal mold in an outer side of the cavity, and an adhesive agent non-application area reaching a position in an inner side of the cavity from a position in an outer side of the cavity.

Methods of fabricating a manhole insert gasket on a manhole insert flange of a manhole insert include fabricating a gasket mold, inverting a manhole insert having a manhole insert flange, placing the manhole insert on the gasket mold with a mold space overlying the manhole insert flange, preparing a gasket material, placing the gasket material in the mold space, finishing the manhole insert gasket by curing the gasket material and removing the manhole insert from the gasket mold. Manhole inserts having a manhole insert gasket characterized by enhanced sealing capability and longevity are also disclosed.

A process for producing gaskets by curing a liquid molding material applied over a plate by a dispenser, wherein in order to improve accuracy in the cross-sectional shape and/or height of the gaskets, the process comprises the steps of: using a dispenser to coat the upper surface of a plate with a liquid molding material, and form a coating layer extending endlessly in a prescribed pattern; and overlapping a molding jig on the plate, the molding jig having in a lower surface a molding groove extending endlessly in a prescribed pattern corresponding to the coating layer, correcting the cross-sectional shape of the coating layer to a cross-sectional shape that corresponds to the molding groove, and curing the coating layer.

Disclosed is a method for manufacturing a substrate-integrated gasket using screen printing. The method includes: a step for forming, on a surface of a substrate by means of screen printing, a coating layer of a paste for forming a gasket; and a step for hardening the coating layer by pressing, at a predetermined height, a coating layer correction member to the coating layer. The cross-sectional shape of the coating layer formed on the surface of the substrate is corrected by means of the coating layer correction member, and in such state, the coating layer hardens to be a gasket, thereby forming a gasket having a highly accurate cross-sectional shape.

A manufacturing method of a gasket adhering to a resin member, the method includes mixing a plurality of liquid materials stored separately and molding the gasket that is made of a mixture of the plurality of liquid materials. The mixture constitutes a liquid silicone-rubber composition that contains a base resin, a crosslinking agent, a curing catalytic agent, a hydrophilic silica filler, and a silane-coupling agent. The hydrophilic silica filler and the silane-coupling agent are contained in different liquid materials before the plurality of liquid materials are mixed.

The purpose of the present invention is to improve the handling and usability of rubber only-type gaskets. To achieve said purpose, a gasket molding is obtained by combining a rubber only-type gasket body with a film carrier obtained from a resin film that holds the gasket body in an unbonded state. The gasket molding is characterized in that: in addition to a gasket-holding section for holding the gasket body, the film carrier has temporary tacking sections that are surface-treated to temporarily tack the gasket body to said film carrier; the gasket body has temporary tack-receiving sections that are temporarily tacked to the temporary tacking sections; and the temporary tacking sections and temporary tack-receiving sections are removed from the film carrier and the gasket body when the film carrier and gasket body are punched into the product shapes.

A polymer sheet includes a polyurethane core. The polyurethane core has a first major surface and a second major surface opposite the first major surface. The polymer sheet can have at least one functional layer overlying a major surface. The polymer sheet has a thickness t.sub.PS. The polyurethane core has a thickness t.sub.PC. In embodiments t.sub.PC can be at least 0.3 t.sub.PS. The polyurethane core can have at least one of the following property: (i) a Scratch Resistance Rating, as further described herein, of not greater than about 10 wt %, (ii) an elongation at break of at least 200%, (iii) a tensile strength at break of at least 0.3 MPa, (iv) a loss of tensile strength of not greater than about 30% when exposed to UV light according to standard SAE J1960 (Rev. August 2003).
The polymer sheet can be used for gaskets or bonding tapes.

A belt molding includes: a molding body, which includes an inner wall, an outer wall, and a connection wall that connects an upper end of the inner wall and an upper end of the outer wall; a design lip, which is formed at the upper end of the inner wall of the molding body; and a design portion, wherein the design portion includes a first portion, which covers at least a part of the molding body, and a second portion, which covers at least a part of the design lip, and wherein a step is formed between the first portion and the second portion, such that a level of a surface of the first portion is different from a level of a surface of the second portion.

Mold for producing a panel assembly comprising a panel and a gasket, which gasket is adhered to the panel, and extends along at least a portion of the periphery thereof, the mold comprising a first mold part and a second mold part that are formed such that the panel can been closed thereby forming a closed cavity the inner boundaries of which are formed by a first mold surface, a second mold surface and the periphery of the panel, and wherein the second mold part comprises a resilient lip extending along the periphery, the resilient lip being provided for being displaced by an applicator device to provide access to the closed cavity.
