A method of manufacturing a vane assembly for an air vent includes comprising molding an intermediate member in a molding die, the intermediate member having a head portion and a stem portion extending distally from the head portion, the stem portion defining a gate for the molding, the intermediate member being an unreinforced polymer material, subsequently molding a vane body over the stem portion of the intermediate member in the molding die, the vane body being a reinforced polymer material, and after molding the vane body over the stem portion of the intermediate member, securing a facia to the head portion of the intermediate member to form the vane assembly.

A blow molded part is provided that includes a first portion consisting of a reinforced resin and a second portion consisting of a non-reinforced resin. The reinforced resin may be fiber-reinforced, and the non-reinforced resin may be a neat resin. In one form, the first portion and the second portion define first and second trim areas, respectively, and the second trim area is directly recyclable. In another form, the second portion comprises a material consisting of a non-reinforced resin and/or a reinforced resin, where the modulus of elasticity of the first portion is higher than the modulus of elasticity of the second portion. Furthermore, a method of forming a blow molded part is provided.

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.

The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.

A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

The present invention concerns a method for producing a flap (3) for a sealing device (1) of a motor vehicle, said method comprising the following steps: extruding a hollow profile section formed from an outer skin (310) made from a first material, cutting the hollow profile section to a predefined length (L) so as to form a flap body (31), fitting end pieces (30) at the ends of the flap body (31). The invention also concerns a flap of a device for sealing a front end air intake obtained by such a method.

It is an object of the present invention to provide a foam molding resin containing LDPE capable of enhancing foaming magnification. According to the present invention, there is provided a foam molding resin containing low-density polyethylene, wherein the low-density polyethylene has a melt tension of 100 to 250 mN and a shear viscosity of 350 to 450 Pa.Math.s.

An active apparatus for modifying aerodynamic properties of a vehicle, encompassing: an apparatus frame; an air flap mounted pivotably on the apparatus frame; and an electric motor for bringing about a pivoting motion of the air flap, the electric motor being embodied as a direct drive for the air flap.

A blow-molded foam is provided by foaming and blow-molding the resin material including a polyethylene resin. The foamed resin includes the antioxidant by 300 ppm or more in total. The antioxidant is preferably the combination of a phosphorus antioxidant and a phenolic antioxidant. The optimum amount of phosphorus antioxidant to be included is 250 ppm to 3000 ppm, and that of phenolic antioxidant is 250 ppm to 750 ppm. In the manufacture, the collected resin material and the resin including 300 ppm or more of the antioxidant are melted and kneaded and the foaming agent is mixed thereto to provide the foamed resin, and the foamed resin is blow-molded.
