Founded in 1898, the Renault Group is a world-famous French automobile manufacturer. As part of a strategy for continuous improvement, Renault and Böllhoff select the RIVQUICK® 7.5 rivet for simpler assembly processes and enhanced productivity.
During the manufacture of the vehicle and the operations to assemble its various components, some parts of the vehicle involve many technical constraints, among which, in some cases, blind installation.
On some specific models, such as the Renault Mégane or the Dacia Duster, during the assembly operations, the operator can attach the rear window wiper mechanism or the soundproofing material to the under-engine fairing only from one side. Moreover, conventional attaching systems require fastener holes with tight tolerances so that correct and permanent joining can be ensured.
These joining operations are traditionally carried out with:
As part of a strategy for continuous improvement, Renault and Böllhoff have taken into account the product/process constraints associated with the materials to be attached in addition to the joining and installation equipment and have investigated new technical solutions to meet increasingly stringent quality requirements.
On several models of vehicles produced by the Renault Group, whether for the installation of the rear window wiper or the soundproofing material of the under-engine fairing, the requirement is the same: attaching a thick plastic component to a thin steel plate or a thin plastic wall. And this operation involves three essential criteria:
RIVQUICK® slotted rivets are designed specifically to meet the requirements of automotive applications. This is the option selected by Renault and Böllhoff. The version with integrated plastic ring is perfectly suited to the rear window wiper.
As a matter of fact, this technology offers major advantages:
As far as the joining process is concerned, bolted joints have been replaced with riveted joints. This now allows only one type of fastener to be used. In addition to eliminating the problem of operator accessibility for the installation of bolts and nuts, riveting is also simpler, faster and more economical.
In terms of product design, the RIVQUICK® rivet allows for fastener holes with significant scattering, thereby making the design work easier and offering considerable savings on the design and manufacture of the parts to be assembled
