A wheel assembly, a wheeled device and a method of manufacturing a wheel assembly. The wheel assembly includes a core and an outer portion coupled to the core. The core includes a body and one or more projections extending from the body. Material of the outer portion may be positioned radially between the body and a portion of the projection to limit radial movement of the outer portion relative to the core. The projection may define a bore and/or an undercut. Material of the outer portion may encompass the projection and fill the bore and/or the undercut. Engagement of the material of the outer portion and the projection(s) may limit relative movement between the core and the outer portion radially, axially, circumferentially, etc.

Plastic panels which are useful as automotive interior trim panels, interior door panels and the like decorative and structural panels, are made by a method which provides an underturned edge onto the panel. The method includes positioning blanks into a mold cavity over top of a mold ring. The blanks are secured to the mold ring and the blank is secured to the mold cavity via a vacuum. The two piece mold is mated together and a substrate is injected into the mold cavity. The cavity is opened, the ring is lifted and the formed part is removed from the mold.

A resin article is made between an outer concave mold part and an inner convex mold part that can fit together so that respective surfaces form a substantially closed mold cavity. This is done by first lining the surface of the outer mold part with a liner sheet and then fitting the lined outer mold part to the inner mold part to form the substantially closed mold cavity. A portion of the surface of the inner mold part is positioned to form a pocket open inward into the cavity and this pocket is filled with a mass of fluent synthetic resin. The surface portion is then pressed inward while the parts are fitted together and without otherwise relatively moving the mold parts to force the resin mass from the pocket into the cavity until the inner-part surface portion lies substantially flush with the rest of the inner-part surface.

An elongated, substantially “C” cross sectioned part and method of making same are provided wherein the part may be injection molded and covered with a paint film on the showside part portions. The method includes the provision of a mold cavity having an inclined nadir wall boundary and moving the female mold away from the stationary male mold part an angle of about 1-20° relative to the widthwise or Y direction. The part includes a plastic substrate and an optional paint film having one edge thereof terminating along the nadir wall behind the show surface of the part.

Door systems and methods of making a door that provide added security in a vehicle, such as a commercial aircraft. An example door system includes a door, a source of pressurized fluid, and a frame. The door includes an injection-molded polycarbonate base, a plurality of hinge inserts embedded within the injection-molded polycarbonate base, and an inflatable seal. The source inflates the inflatable seal. The frame includes hinges that attach to the plurality of hinge inserts.

An injection mold for producing a plastic injection molding having a layer of plastic molding material on the front of a metallic support. The injection mold has a first mold half over the front of the support with a mold cavity therein for holding the injected plastic material which forms the layer on the front of the support. The injection mold has a second mold half at the rear of the support with another recess for being filled with pressure fluid for pressing the front of the support against the first mold half, which seals the cavity for the injected plastic molding material to prevent leakage and to keep the line of the plastic material layer around the mold cavity on the support sharp. The pressure fluid may be supplied to the rear of the support before the molding composition is injected into the cavity at the front of the support. The pressure fluid at the rear of the support may be the same material that is applied on the front of the support. The recess in the second mold half at the rear of the support is adjacent but alongside the cavity defined in the first mold half above the front of the support, and their adjacent edges are either directly one above the other or each slightly overlaps the other recess.
摘要:
A moldable wire thread insert for reinforcing a screw-in opening of a component has the following characteristics: a cylindrical spiral made of a helically, wound wire, the neighboring coils of which are arranged such that a closed cylindrical spiral wall is present, while at least one end of the cylindrical spirals has a fastening flange, which extends radially outwards over the cylindrical spiral wall and with which the wire thread insert is anchorable in the component and/or one end of the cylindrical spiral is designed in a planar manner in order to form an even axial front surface of the cylindrical spiral.
