A method for producing a laminated moulded part comprises a pressure moulding of a blank to form a moulded part in a moulding cavity between a first moulding tool unit and a second moulding tool unit, introducing of a laminating element into the moulding cavity after the pressure moulding of the blank, and a bonding of the moulded part with the laminating element in the moulding cavity.

An optical element includes a first substrate having a first surface, a resin member disposed on the first surface, and a second substrate disposed above the resin member with a joining member interposed therebetween. The resin member has a first region contacting the joining member and a second region surrounding the first region and not contacting the joining member. An inclined portion having a thickness increasing from a starting point located in the second region toward an outer circumference of the resin member, is disposed in the second region. A tangent of the first surface, orthogonal to a normal of the first surface passing through the starting point, and a straight line passing through the starting point and a point at which the inclined portion has a largest thickness, form an angle of 25 or more and 45 or less.

The present invention relates to a process for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating comprising a novel moulding and spraying step, wherein said HMA material, preferably HMPSA material, can be easily handled, packed and transported for further use. In addition, the present invention relates to a corresponding device for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating.

A method for manufacturing a composite includes providing a first template including a cutout for a first layer of the composite, disposing the first layer in the cutout, and disposing a tablet, provided with an adhesive, on the first layer such that the first layer adheres to the tablet. Next, the tablet is removed, together with the first layer adhered thereto, from the cutout, and an adhesive is applied to a side of the first layer facing away from the tablet. A second template is provided that includes a cutout for a second layer of the composite, and then the second layer is disposed in the cutout. The tablet, together with the first layer adhered thereto, is disposed on the second layer disposed in the cutout of the second template, and the tablet is removed, together with the composite produced from the first and second layers, from the second template.

A metal cap in which a linear to be held to a cap body and separable from the cap body can be formed by a series of operations for forming the cap body and press molding the liner. The liner of the metal cap has a double-layer structure including a barrier layer on a top panel wall side and a sealing layer on the inner side of the cap body, and the barrier layer is temporarily bonded to the top panel wall with a weak adhesive at the time of molding the barrier layer and separated from the top panel wall by the natural cooling of the barrier layer after molding.

Disclosed herein is a vehicle spoiler, and more particularly, a vehicle spoiler with improved adhesive strength between a fixing member and a spoiler body due to a structure of the fixing member which is provided with an adhesive surface surface-treated in an embo shape and a protrusion formed to protrude at a predetermined height in a vertical direction of the adhesive surface, and a manufacturing method thereof. The vehicle spoiler includes a spoiler body installed in a vehicle trunk in a width direction and formed in a plate shape, a fixing member which is coupled to a lower surface of the spoiler body in a vertical direction and which includes an adhesive surface having one surface undergoing surface treatment and a protrusion formed to protrude at a predetermined height in a vertical direction of the adhesive surface, and an adhesive applied to the adhesive surface of the fixing member.

A seat trim cover for an automotive seat is formed into a 3-dimensional shape by compression molding a laminated moldable foam in a 3-dimensional. The laminated moldable foam comprises at least a layer of cellular polyurethane foam compression moldable in a temperature range of about 220? F. to about 260? F. The 3-dimensional mold is heated to a temperature range of about 150? F. to about 320? F. The layer of cellular foam is adhered to a cover material layer and pre-cut into a pre-laminated blank prior to molding into the 3-dimensional shape. Optionally, seat heaters or other components can be integrated with the laminated foam prior to compression molding the seat trim cover.

Methods of producing polymer-metal hybrid components that are bonded by CO-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong CO-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (CO) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed CO-M bonds at the interface.

A method for trim preparation of car interior parts includes the steps of cutting out templates of natural jute or linen fabric primer and a second natural cotton fabric or fiber paper, and impregnation of the fabrics with a water-based adhesive resin in each of the fabrics and drying thereof. The method also includes the steps of fabric pressing, forming a structure by adding an adhesive layer and a decorative sheet, applying primer on the decorative layer and drying it, and applying at least one layer of varnish onto the primer layer and drying it.

A cover (1), in particular a backrest cover or a lateral cover for a vehicle seat, is molded from a covering material layer (2), in particular from a covering material blank (2.1) and from a carrier material layer (4), in particular from a carrier material blank (4.1). An adhesive non-woven (3) or an adhesive layer is disposed between the covering material blank (2.1) and the carrier material blank (4.1).
