A method for manufacturing a fuel tank using a polyketone, according to the present invention, comprises: a cover injection-molding step for injection-molding an upper cover and a lower cover through an injection-molding machine; a cover assembly step for disposing the upper and lower covers, which have been injection-molded through the cover injection-molding step, at upper and lower positions, respectively, and then assembling the same; and a cover welding step for welding the contact surfaces of the upper and lower covers, which have been assembled in the cover assembly step, with a laser. Accordingly, the present invention may provide a fuel tank made of a polyketone and a manufacturing method therefor, in which a pair of upper and lower covers are simultaneously molded and extracted, assembled through a machine, and then directly welded to each other, whereby it is possible to achieve automation, mass-production, and a marked reduction in cost, and necessary rigidity is satisfied by only the rigidity of a polyketone material without any separate reinforcing object, whereby it is possible to achieve weight reduction of a fuel tank.

The present invention concerns an assembly method for assembling at least a first part 1 and a second part (2), each one of said first and second parts (1,2) comprising at least a first bonding lip (5,9) with a bonding surface (3a,3b). The method comprises the steps of inserting the first bonding lip 9 of the second part (2) between the first bonding lip (5) and a guiding lip (11) of the first part (1) until engaging an oblique front face (12) of the guiding lip (11), closing the bonding surface (3b) of the first bonding lip (9) of the second part (2) against the bonding surface (3a) of the first bonding lip (5) of the first part (1), wherein the first bonding lip (9) of the second part (2) is guided towards the first bonding lip (5) of the first part (1) by the oblique front face (12) of said guiding lip (11), and bonding the bonding surface (3a) of the first bonding lip (5) of the first part (1) to the bonding surface (3b) of the first bonding lip (9) of the second part (2). The present invention also concerns an assembly A obtained by this method.

Provided is a resonator made of synthetic resin provided in an intake path of an engine. An air chamber forming the resonator is formed by melt-welding a circumferential wall portion of a first box forming body and a circumferential wall portion of a second box forming body, while abutting the circumferential wall portions against each other, the first box forming body including a bottom surface portion and the circumferential wall portion surrounding the bottom surface portion, and the second box forming body including a bottom surface portion and the circumferential wall portion surrounding the bottom surface portion. A circumferential groove is formed on an upper end portion of the circumferential wall portion of the first box forming body, and a circumferential protrusion is formed in an upper end portion of the circumferential wall portion of the second box forming body, the circumferential protrusion being melt-welded to a groove bottom of the circumferential groove by being received in the circumferential groove during abutment. An upper end surface between an outer wall surface in the circumferential wall portion of the first box forming body and the circumferential groove is located above the upper end surface between the inner wall surface and the circumferential groove.

A method for reliably attaching a liquid-repellent filter to an air vent of a resin molded article in which an electronic part or any other component is accommodated, and a thermally processing tip and a thermally welding tip used in the method as well as a molded article are provided. A thermally processing tip 22 is used to form a filter attachment surface 14, onto which a filter 18 is dropped, at the inlet or outlet of an air vent 16 formed in a thermoplastic resin molded article 13, and a filter fixing rib 15 is formed around the attachment surface 14. The porous filter 18 is then dropped onto the filter attachment surface 14, and a thermally welding tip 2 is used to melt the filter fixing rib 15 in such a way that the melted resin is caused to flow onto and cover a circumferential edge portion of the filter 18 and penetrate the body of the filter 18. Thereafter, the melted resin penetrating the filter 18 and the melted resin covering the circumferential edge portion of the filter 18 are so cooled as to solidify, whereby the filter 18 is fixed to the filter attachment surface 14.

Joints for joining panels (60, 62) together, such as for joining honeycomb sandwich panels used in aerospace applications, and methods of joining said panels are disclosed. In some examples of disclosed joints, a first panel and a second panel can be joined together to form a joint. The first panel (60) can be a flat panel that includes a rabbet (80) formed along a first longitudinal edge, and the second panel (62) can be a curved panel that includes a notch (86) formed along a second longitudinal edge. In forming the joint, a portion of the rabbet (80) can be positioned within the notch (86), and the flat panel (60) and curved panel (62) can be oriented at a non-parallel and non-perpendicular angle to one another. Adhesive (99) is applied along the rabbet (80) and/or the notch (86) in order to secure the joint.
摘要:
An air duct pipe (2) for a combustion engine, particularly for a motor vehicle, consisting of at least two pipe parts (4, 6) that are fabricated of a plastic material by means of injection molding and that are connected to one another along an interconnecting line (8) that consists of an interconnecting duct (10) that is formed by interconnecting parts (12, 14) for each respective pipe part in the area of the interconnecting line (8). The pipe parts (4, 8) are connected to one another and sealingly joined to one another by injecting said plastic material into said interconnecting duct (10). The interconnecting parts (12, 14) comprise inner interconnecting parts (16, 18) that are designed so that they form a uniform interconnecting surface (20) on the inside of the air duct pipe (2) and are adapted so as to absorb pressure from the interconnecting duct (10) during the injection of said plastic material into the interconnecting duct. Said interconnecting parts (12,14) comprise outer interconnecting parts (22, 24) that are adapted so as to mechanically keep the pipe parts interconnected.
