Bonding objects together
A method of bonding a first object to a second object includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object including a proximal surface, applying a mechanical pressing force and a mechanical excitation capable to liquefy the thermoplastic material until a flow portion of the thermoplastic material is flowable and penetrates into structures of the second object, and stopping the mechanical excitation and letting the thermoplastic material resolidify to yield a positive-fit connection between the first and the second object. The second object has a region of low density, wherein the protrusion penetrates the region of low density at least partly before the thermoplastic material is made flowable, and wherein the first object includes a protruding portion after the step of letting the thermoplastic material resolidify, the protruding portion at least partly penetrates the region of low density.
Decorative part for a motor vehicle
The invention relates to a decorative part (11) for a motor vehicle and a method for the production thereof, having a carrier part (18) and having a covering part (12) made of a single-pane safety glass, which are connected to each other, wherein a bonding agent layer (17) is applied over the entire surface on a fixing side (16) of the covering part (12) opposite the visible side (14) of the decorative part (12), and a layer made of a thermoplastic elastomer (26) is provided over the entire surface on the bonding agent layer (17), by means of which the carrier part (18) is fixedly connected to the covering part (12), wherein at least one sealing lip (34, 51) is moulded on the TPE layer (26).
Method of folding edges of trim parts
A method of folding edges of trim parts includes the following steps. Place an inner surface of a substrate against a panel support so that an upper end of the substrate is disposed above a top end of the panel support. Press a backup blade against an outer surface of the substrate beneath the upper end of the substrate. A folder tool of an edge folding apparatus is urged against the inner surface of the upper end of the substrate in a horizontal direction which laterally folds the upper end 96 of the substrate. Remove the backup blade from the outer surface of the substrate. Then urge the folder tool of the edge folding apparatus against the inner surface of the substrate in a vertical direction and downwardly folding the upper end 96 of the substrate.
Method for producing a trim part of a motor vehicle
A method for producing a three-dimensionally shaped trim part of a motor vehicle, which has a visible side and a mounting side. A flowable material is injected with pressure into a chamber of an injection molding tool, which has at least two mold shells, which, when assembled, form the chamber with a negative mold of the trim part, wherein at least one first of the mold shells forms the visible side and at least one second of the mold shells forms the mounting side of the trim part. The material is hardened in the chamber. A gas pressure is generated that acts in a planar manner between the second mold shell and the material during the hardening. The hardened material is removed as a trim part from the chamber of the injection molding tool.
Attachment part for connecting to a structural part
An attachment part for connecting to a structural part. The attachment part has an attachment part longitudinal axis, and a weld portion to be welded to the structural part by torsional ultrasonic welding. The weld portion has a contact surface for contact with a torsion sonotrode, and a weld surface for connecting to the structural part. The weld portion is delimited, at least portionally, by an inner vibration decoupling zone. The inner vibration decoupling zone, at least portionally, surrounds an inner portion of the attachment part.
Elastomeric composite polyurethane skins
An elastomeric composite polyurethane skin having an average flexural modulus, measured in accordance with ASTM D790-03, smaller than 35 MPa is disclosed. The elastomeric composite polyurethane skin includes a first aliphatic polyurethane layer made from a first polyurethane reaction mixture having at least one isocyanate compound with at least two NCO-groups which are not directly attached to an aromatic group, at least one isocyanate-reactive component (B1), and at least one catalyst component (C1) substantially free of lead, and a second aromatic polyurethane layer made from a second polyurethane reaction mixture having at least one aromatic isocyanate compound (A2), and at least one isocyanate-reactive component (B2).
Liftgate reinforcement arrangements
A liftgate structure having a structural inner panel with an outside surface and an inner surface having a lower perimeter surface area extending across substantially the entire width of the structural inner panel. The structural inner panel includes a wiper motor housing recess formed on the inner surface. A plurality of brackets are connected to the outside surface of the structural inner panel, where each of the brackets has at least one friendly hole. The liftgate structure further includes a tether having 2 ends each having at least one over molded retainer for connecting the tether to a wiper motor housing positioned within the wiper motor housing recess of the structural inner panel. Additionally the tether is positioned through each of the at least one friendly holes of the plurality of brackets.
Composite sidewall and cargo body having same
A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a recess. The core thickness at the recess is reduced compared to a maximum core thickness, and the recess defines a support surface. A pocket is formed in the recess, with the core thickness at the pocket being less than the core thickness at the recess. A logistics insert is attached to the support surface of recess so that, at the recess, the logistics insert extends across the pocket.
Sound protection panel for cladding a wall of an automotive vehicle
The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.
METHOD FOR PRODUCING COMPONENTS OF AN OUTER SKIN OF A VEHICLE
A method for producing components of an outer skin of a vehicle with a film, which is back-molded at least from one a front side or rear side with clear plastics material, includes subjecting the film to a thermoforming process in order to generate the desired three-dimensional form. The film is subjected to further steps for preparation of the back-molding, including providing the film at least partially with a color layer. The film includes regions, through which other colors are intended to show through and be visible from the front side, or electromagnetic waves are intended to pass. The film may be punched-out in the regions to define punched-out portion in which components are inserted. The components are attached to the film by adhesive and/or overmolding on the rear side.
