摘要:
A method of manufacturing a molding product of an image sensor unit having a molded product with a substantially rectangular parallelpiped outer shape and incorporating a substrate on which photoelectric conversion elements are arranged in line, includes the steps of forming a frame on the molded product to surround a periphery of the substrate, forming a plurality of caulking projections substantially linearly arranged on an upper surface of the frame in a longitudinal direction, with each caulking projection having a proximal portion extending from the frame, and forming a plurality of antiwarping grooves, with each groove being proximate to one of the caulking projections but spaced apart from its respective proximal portion. Additional steps include fitting the substrate to be fixed in the frame of the molded product, and bending the caulking projections by heat and pressure to fix the substrate in the frame.

The invention relates to a method of fastening first and second thermoplastic parts of a motor vehicle, the first part having a protuberance projecting from a face and the second part having an engagement surface, the method consisting in bringing the second part into contact with the face of the first part, in heating the protuberance, and in plastically deforming the protuberance towards the second part so that the second part is gripped between the face of the first part and an end portion of the protuberance.

A method for fabricating an automotive trim which is mounted with an ornamental member, in which an ornamental member which is not molded by any preliminary forming process is secured on a surface of a door trim main body with a bonding die set so as to closely follow a complicated surface profile of the door trim main body, extraneous parts of this ornamental member is cut by a thermal cutting blade attached to the bonding lower die, and the peripheral edge of the ornamental member is finished by a pressure bar.

A method of producing a laminated panel having a backside formed of a normally rigid substrate, such as a polymer/filler composition, in an essentially self-supporting thickness of typically between 1 and 10 mm and a frontside formed of a differentially segmented cover layer, e.g. having segments of differing materials and/or colors, bonded to said substrate by laminatingly interconnecting, typically at elevated temperatures and pressures, a layer of said substrate in a moldable, e.g. thermally plastified state and a differentially segmented sheet for forming said cover layer; the sheet has at least one seam line between adjacent segments; in order to compensate the effects of an off-set between the position of the seam line of the segmented sheet and the desired position of the seam line between segments of the laminated panel the novel laminating method includes the step of forming a fold to protrude from the backside of the final laminate; the fold consists of a folded double layer of the segmented sheet as an inner fold portion and of an outer fold portion formed of the substrate; the folded double layer has a length corresponding to at least about 100%, typically between 100 and 300%, of the self-supporting thickness of the substrate and embeds the seam line of the segmented sheet within the fold so that the visible junction between differing segments on the frontside will be defined by the visible end of the folded double layer.
摘要:
A method and apparatus is provided for forming a power distribution system during a punching operation. A planar member of conductive material is located proximate to the substrate upon which the power distribution system is to be formed. A punch used to form the conductors from the planar member and deposit the conductors on the substrate. The action of the punch causes mechanical interference between the conductor and the substrate thereby securing the conductor to the substrate.
摘要:
Method and apparatus for blow molding double-walled containers from thermoplastic polymers in which the inner and outer container parts are simultaneously molded in a single tandem mold in the same molding cycle to produce special single-piece molded container intermediates. The intermediate is then cut apart along specially provided cut lines to provide a continuous inner container and a multipiece outer container in which the inner container nests. Loose, molded or batt-type insulation may be employed in annular space between the outer shell and the inner container. The outer container parts, bottom and top, are designed to snap-fit together. A carrying or pouring handle may optionally be molded into the outer shell part, or spout to the inner, or they may be added as separate pieces.

Collapsible toothpaste and like dispensing containers having flexible body walls and externally threaded discharge necks are formed by wrapping a sheet of flexible material about a mandrel and fastening overlapping side edges together to provide a tubular body shell having a longitudinal seam, and then inserting and clamping one end of the formed body shell between nested mechanically interengaged inner and outer head structure elements.

Apparatus for the joinder of edge portions of sheet material into a sealing joint by arranging sheets with edge portions to be joined in aligned superposed relation and providing a blank of thermoplastic material having a shape and dimension corresponding to the shape and dimension of the edges to be joined including first and second platen elements movable toward and away from one another and shaped to contact and fold said blank about the edges of said sheets.
