Clamping Rails For BMW
The project at a glance
The clamping rail for our customer, BMW, is part of a complex system component used in the bodywork area, including the MINI Cooper. As a structural element, it affects the preservation of dimensions, stability and assembly accuracy of the vehicle structure. A characteristic feature of this design is the high level of production, in which several process steps are combined into a ready-to-assemble serial subassembly.
Technical implementation of the project
The Challenge
When carrying out body projects — for example for the BMW MINI Cooper — we were faced with the challenge of creating a functional clamping rail as a complex system component. The project required the precise manufacture of three separate components, their exact positioning relative to each other and a permanent connection. In addition, the process required the preservation of a strictly defined sequence of follow-up operations. Even slight deviations in the geometry or sequence of processes would negatively affect the functionality and the ability to install the subassembly in the vehicle.
Solution
Thanks to the integrated production in MM Systemy, all process steps are precisely matched to each other. Three individual components are manufactured in our stamping plant department on the Arisa 800 LD servo press and then spot welded on the Lewa line. The next steps include cataphoretic painting (KTL) for corrosion protection and precise pasting with EPDM gasket as part of the assembly. The result is a ready-to-assemble subassembly, mass-produced with full repeatability and seamlessly integrated into the automotive manufacturing process.
System production from a single source
The uniqueness of this project lies in the controlled synergy of several production technologies. Only a precise combination of stamping, welding, coating and assembly makes it possible to maintain consistent serial quality at such a great depth of production.
“When we supply the terminal rail for the MINI Cooper, we offer a component that is part of a larger component in the front section of the vehicle. This project shows how within our group we realize complex components from a single source.”
