company news about Ultrasonic plastic riveting technology in the automotive industry

1. Annular airbag cover riveting

The airbag walnut wood veneer cover is made by arranging a plastic hollow rivet on the back of the decorative board and then riveting it together with the stamped thin metal plate skeleton. The airbag walnut wood veneer plate combines the surface handleability of the plastic component with the rigid metal structure of the stamped metal, and has the characteristics of good elasticity, no sharp edges, uniform stress distribution, simple and light structure, etc. In the event of an accidental collision, the product can maintain structural integrity without sharp fragments, not only can prevent collision and energy absorption, but also effectively reduce material consumption and reduce the weight of the body. Provides better security.

2. Lamp plastic riveting

The application of riveting technology in the internal circuit of the ceiling lamp in the car. The reserved studs on the plastic seat of the ceiling lamp pass through the pre-punching holes on the metal sheet, and then the metal plate conductors are riveted by the hemispherical round caps, and the parallelly placed metal pieces are separated by the vertical ribs to make them insulated and shackled. This can effectively prevent the vibration of the metal piece conductor from falling off, and fundamentally eliminate the short circuit phenomenon.

3. Door trim riveting

The trim panel skin component that is riveted to the press-formed wood fiber door frame uses an air core riveting column (tubular hot pile) for the outer flange riveting process. Due to the large contact area of the eversion edge and the high connection strength, the loosening, falling off or tearing caused by long-term vibration can be effectively avoided, so that the whole component can more effectively realize the functions of sound absorption, noise reduction and thermal insulation. Effectively improved the interior environment. In the narrow part near the edge, the vertical rib riveting process is adopted to increase the contact area of the rivet cap, and the phenomenon of tearing and falling off when the force is applied at the edge is prevented, thereby effectively overcoming the shortcoming of the poor stretching effect of the wood fiber board. , and finally combined with plastic parts into a structure.

4. The back of the speaker assembly.

The black part is the inner support/snap structure, the material is ABS+PC plastic alloy, the speaker decorative panel grille is metal mesh, and the frame trim is made of metal silver-gray ABS plastic. The assembly combines the good visual effect of electroplatable ABS plastic with the high strength and high impact resistance of ABS+PC plastic alloy. The red arrow in the figure points to the riveting point. The pre-molded riveting of the ABS decorative cover passes through the corresponding hole in the ABS+PC alloy structural member, and is connected by a flat head riveted joint for better performance. Can reduce weight and processing costs.
