An inlet duct for an internal combustion engine includes a duct member made of a compression molded fiber material. The duct member includes a main body and end portions provided on opposite sides in an axial direction of the main body. The main body includes at least one high-compression portion and at least one low-compression portion, which is made through compression molding at a compression ratio lower than that of the at least one high-compression portion. The at least one low-compression portion extends throughout a length in the axial direction of the main body.

The invention relates to a method for producing a body component (1) for a motor vehicle (2), said body component (1) being made of a main body (3), formed from a batt that is embedded in a plastics matrix, and comprising at least one air-removal device (4), in particular for removing air from an interior (5) of the motor vehicle (2). The air-removal device (4) comprises at least one ventilation opening (7) that can be reversibly sealed by means of at least one ventilation flap element (6).

A method for producing a densified material includes: obtaining a film including at least one first layer of plastic material and one second layer with a composition distinct from the first layer, the first layer having a first melting temperature, or obtaining pieces of such a film; compressing the obtained film or the obtained pieces of film through at least one die of at least one extruder, and obtaining a profile of densified material, the extruder including at least one rotary endless screw pushing the obtained film or pieces of film along a screw axis; and optionally cutting the profile in order to obtain granules of densified material, the compression step being carried out at a maximum compression temperature for the obtained film or pieces of film, the maximum compression temperature being less than the first melting temperature. Also disclosed are installation and use of the densified material.

Disclosed herein is a baffle for regulating air flow around an object. The baffle can be of unitary construction and can be made by a single shot injection molding process. The baffle can have an edge portion that is more flexible than the base portion. The baffle has also can have a base portion with a base portion thickness and an edge portion with an edge portion thickness that is less than the base portion thickness. A method of making a baffle by an injection molding process is also disclosed.

An air extractor manufacturing method includes, among other things, molding at least one flap in a sealed position against a housing of an air extractor. The housing has a first material composition and the at least one flap has a second, different material composition. An air extractor assembly includes, among other things, a housing having a first material composition; and a flap having a different, second material composition. The flap is moveable relative to the housing between a sealed position and a pressure releasing position. The flap is molded in the sealed position and coupled to the housing when molded.

An interior component of a vehicle includes a basic body (10) on which there is arranged a decorative element (14) which is produced in an extrusion process and which has a different surface nature than the basic body (10).

Disclosed herein is a baffle for regulating air flow around an object. The baffle can be of unitary construction and can be made by a single shot injection molding process. The baffle can have an edge portion that is more flexible than the base portion. The baffle has also can have a base portion with a base portion thickness and an edge portion with an edge portion thickness that is less than the base portion thickness. A method of making a baffle by an injection molding process is also disclosed.

Generation of a balloon-shaped air bubble is suppressed. A foam molded article according to a mode of the present disclosure is characterized in that in a situation of being divided into two equal parts in the thickness direction T of the foam molded article, the average cell diameter 1 in the thickness direction T on the inner surface side A of the foam molded article is 1.2 times ((1/1)=1.2) or greater of the average cell diameter 1 in the thickness direction T on the outer surface side B of the foam molded article and that the surface roughness Sm of the inner surface of the foam molded article is 1000 m or greater.

An assembly method for assembling a structural element and a functional element constituted of a first functional element part and a second functional element part. The method includes the steps of (a) bringing into contact the first functional element part, the second functional element part and the structural element in at least one assembly zone, with the first functional element part being in contact with the second functional element part, and the first functional element part and the second functional element part being respectively in contact with the structural element in the assembly zone, and (b) welding of the first and the second functional element parts on to the structural element in the assembly zone in a single welding pass in a manner so as to simultaneously attach the first and the second functional element parts to the structural element.

Provided is a duct that does not cause defective molding and has a highly sound absorption inner surface which can effectively suppress noise. A duct includes a tubular duct main body and a sound absorption member disposed on the inner surface of the duct main body. The duct has at least one of configurations (1) to (3): (1) the duct main body has a sandwiching part having a pair of opposite wall surfaces, and a side edge of the sound absorption member is sandwiched between the wall surfaces of the sandwiching part; (2) the sound absorption member is pasted to the inner surface of the duct main body with a resin film therebetween; and (3) the sound absorption member and duct main body have parts which are not fused to each other.
