A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14. The mask body 12 includes a supporting frame structure 16 and a filtering structure 18. The frame structure is injection molded onto the filtering structure 18 such that the frame structure 16 becomes bonded to the filtering structure 18. A mask body having such a support structure allows the filtering structure to follow its configuration closely, providing improved aesthetics and collapse resistance to the resulting article.

A method for producing a thermoplastic resin molded article having a thermoplastic resin foam substrate and a functional member joined by welding to the foam substrate is provided. In order to prevent the occurrence of dimples on the surface of the molded article at the joined portion of the functional member, the molding of the functional member is performed while a pressure-resistant sheet is placed at an extended portion of a molten resin feeding gate provided at the bottom of a cavity for forming the functional member.

A diffuser assembly includes a flexible diffuser membrane and a diffuser body. The flexible diffuser membrane defines a circumferential bead. The diffuser body defines a circular plate underlying the flexible diffuser membrane, and an edge ring covering a covered portion of the circumferential bead. The edge ring defines an inside surface that conforms to an outside shape of the covered portion of the circumferential bead. The edge ring is integral to the diffuser body. Such a diffuser assembly may provide a disposable diffuser assembly option with many advantages over conventional technologies such as improved ease of installation, lower weight, and lower cost.

A frame for a vehicle sliding sunroof or tilt-slide sunroof is proposed, comprising at least one single-piece frame base element (22), that is embodied as a plastic injection-molded piece and comprises at least one front frame piece (24) and two side stringers (26, 28) that are directed in the vehicle's longitudinal direction. For formation of a light and stiff frame, the frame base element (22) according to the invention is embodied as a composite component, and provided with at least one profile- or cup-shaped inserted piece (38, 40) that serves as a reinforcing element.

The process comprises injecting a melted plastic material into a mold in which a plate part (10) is arranged with at least one hole (13) inter-placed between first and second cavities (21, 22), then withdrawing the plate part (10) from the mold with at least one reinforcing rib (30) of plastic material adjacent one side (11), and at least a projection integral to the rib (30), projecting on the other side (12) through the hole (13), and finally deforming said projection by application of heat and pressure to form a fixing head (32) with a grip configuration (33). The composite structural part is integrated by the plate part (10) and the reinforcing rib (30) firmly connected thereto by means of said fixing head (32).
摘要:
Integral structures are formed using a combination of both metal and plastic and including fastening means to secure the plastic to the metal. Several types of fastening means are disclosed. Ribbed structures in which metal is suitably joined with injection molded plastic are also contemplated herein.

A method of constructing a frame (10) for a filtering screen from a polymer material is described in which a wire frame reinforcement is wholly encapsulated during the frame moulding process so that two parallel spaced apart wires extend through each of the intersecting orthogonal ribs (14, 16) which define the open area of the frame (10) across which the wire-cloths (158, 159) are stretched. The surfaces of the frame (10) in which the wirecloths (158, 159) are embedded are formed with ridges (22, 30, 32) and the crests of the latter extend to different heights. The crest are softened by heating during the manufacturing process and the wirecloths (158, 159) stretched over the frame (10) are forced into the softened crests after which the assembly is allowed to cool and cure. The frame (10) is re-usable by stripping wirecloths (158, 159) from the top of the frame (10) and fitting fresh wirecloths over the plastics material and heating the regions which are to encapsulate the fresh wirecloth.
摘要:
A method for manufacturing a plastic speaker grill is provided. The method includes the steps of providing a base member having a first side and an opposing second side and defining a thickness therebetween. The base member has a plurality of spaced blind holes wherein the first side is in communication with the plurality of blind holes and the second side defines a surface that is generally uniform and uninterrupted. The method further includes cutting the base member proximate the second side to remove a portion of the base member and define the speaker grill, and in response to cutting the base member, exposing the blind holes wherein the blind holes define apertures that extend completely through the speaker grill. A plastic speaker grill is provided having tightly-spaced and miniscule apertures.
摘要:
A method and apparatus for molding a plastic element having a body with a surface from which at least one rib extends and an insert at least partially arranged against the surface and under the rib. The method carried out by the apparatus includes the steps of: (a) installing the insert against a wall of an injection cavity, the wall having at least one slit extending at least partially opposite at least one part of the insert, the slit being adapted to form the rib of the plastic element; and (b) injecting molding material into the injection cavity to create the body and the rib of the plastic element. A support element is positioned in the slit, against the insert, to support said insert during the injection.
