Summary First time to allow variable geometries in a "continuous" extrusion process for this type of application. The process allows flexibility to make separate part numbers in the same extrusion. Weight Savings: None. Cost Savings: 20% Cost Avoidance: Reduced flash improving the quality of the parts right off the line thus avoiding cost of trimming.
Most Innovative Feature First time to allow variable geometries in a "continuous" extrusion process for this type of application.
Other Innovative Features The process allows flexibility to make separate part numbers in the same extrusion.
Forming Process Corrugation extrusion, not a newly invented process, but the first time adapted for this automotive application area.
First time process used? Yes. Never before has anyone tried to adapt this technology for a boot application requiring mounting/sealing at both ends.
Previous Process Used Same materials were previously used, but only via the extrusion blow molding process.
Tooling Innovations This will be described during the presentation. Drawdown considerations were intricate.
New Material Developments None were required.
Weight Savings None.
Direct Cost Savings Introduction of this part immediately saved ~20% for the customer. Consequently, the entire market price has been lowered and subsequent savings are 10-15%.
Indirect Cost Savings The corrugation process reduces flash improving the quality of the parts right off the line thus avoiding cost of trimming.
Translates to other Vehicles? Yes. Additionally, the process will be employed to make steering column closeouts, again shifting the dynamic of how parts are made and costed.
Safety Benefits None.
Environmental Benefits
