A method for forming an in-mold coating multi-layer coating film includes: forming an uncured first in-mold coating film by injecting a specific first in-mold coating material composition (X) between a molded base material and an inner wall of a first film coating mold; heating and curing the uncured first in-mold coating film; separating the first film coating mold from a surface of the cured first in-mold coating film; providing a gap between the surface of the cured first in-mold coating film and a second film coating mold; forming an uncured second in-mold coating film by injecting a specific second in-mold coating material composition (Y) between the surface of the cured first in-mold coating film and an inner wall of the second film coating mold; and heating and curing the uncured second in-mold coating film.

A ladder having a first rail having a bottom and a web, a first flange attached to a first end of the web and a second flange attached to a second end of the web. The ladder having a second rail. The ladder having rungs attached to the first rail and second rail upon which a user steps to climb the ladder. The ladder having a foot having a plastic body with a recess which receives the end of the first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has an edge positioned about the body with perforations, and a rubber tread disposed along an underside of the base and extending through the perforations and along the edge on the top side of the base to form an overmolded portion of the tread that attaches the tread to the base without any mechanical or other types of fasteners. The rubber tread forms a bond with the underside of the base and the edge on the top side of the base. The foot for a bottom of a rail of a ladder. A method for placing a ladder. A method for producing a foot for a bottom of a rail of a ladder.

A method for imparting hand-tearability to an organic polymeric film by impinging a multiplicity of ceramic microblades on a major surface of the organic polymeric film. The resulting microfractured organic polymeric film can be used as a hand-tearable tape backing for a hand-tearable adhesive tape.

A manufacturing method and structure for a composite material racket frame includes the following steps: (a) Resin impregnation: Impregnate a composite material with resin; (b) Wrapping the core mold with composite material: Use a core mold in the shape of a racket, made of polymethacrylimide (PMI) or expanded polypropylene (EPP) material; then wrap the composite material around the core mold to form a composite material layer. The mutually wrapped composite material layers and core mold together form a semi-finished product; (c) Heating and pressurizing: Place the semi-finished product into a mold with a cavity, and heat the mold to a preset temperature. After heating, the core mold expands due to heat, forming internal pressure within the semi-finished product; (d) Cooling and curing: Stop heating and allow the semi-finished product to cool until it reaches a cured state, and (e) Finished product formation: Remove a finished racket frame from the mold.

A polymer molded article including: a base portion; and a surface layer portion thermally bonded onto the base portion, wherein the polymer molded article satisfies the following requirements: 1) Gs>Gb where Gs is a rigidity of the surface layer portion, and Gb is a rigidity of the base portion; and 2) Tms<Tp where Tms is a melting point of the surface layer portion at a joint portion with the base portion, and Tp is a molding temperature during the thermally bonding.

Provided is a resin molded body including: a resin porous body that contains a carbon fiber nonwoven fabric and has continuous voids; and a skin layer formed of a thermosetting resin composition. In this resin molded body, the continuous voids have a porosity of 50% by volume to 97% by volume, the skin layer has a porosity of 5% by volume or less, and the thermosetting resin composition is embedded at a depth of 50 m to 1,000 m on the resin porous body side of the resin molded body. Also provided is a method of producing a fiber-reinforced resin molded body, the method including, in the order mentioned: the preform forming step of forming a preform using a resin porous body that has continuous voids and a flexural modulus of 10 MPa or more based on the ISO178 method (1993); the sealing step of forming a closed space that encloses the preform with a molding die and/or a film; the injection step of injecting a thermosetting resin composition into the closed space; and the curing step of maintaining a temperature equal to or higher than a curing temperature of the thermosetting resin composition. This method provides a resin molded body that contains a porous structure and is excellent in surface quality and productivity.

A foam part for a vehicle seat having a textile layer and a foam body made from a polyurethane foam. The textile layer may be designed as a three-dimensionally formed non-woven layer. The non-woven layer may have a grammage of 800 to 1200 grams per square meter. A method for producing the foam part and for providing the vehicle seat having at least one foam part are described.

A method for forming an in-mold coating multi-layer coating film includes: forming an uncured first in-mold coating film by injecting a specific first in-mold coating material composition (X) between a molded base material and an inner wall of a first film coating mold; heating and curing the uncured first in-mold coating film; separating the first film coating mold from a surface of the cured first in-mold coating film; providing a gap between the surface of the cured first in-mold coating film and a second film coating mold; forming an uncured second in-mold coating film by injecting a specific second in-mold coating material composition (Y) between the surface of the cured first in-mold coating film and an inner wall of the second film coating mold; and heating and curing the uncured second in-mold coating film.
