PLUGG II - From Concept to an Idustrial Jointing Technology
Purpose and goal
The aim of the project was to develop an efficient process for mechanical joining based on PER (Plug Element Riveting) of multimaterial. The technology was taken from the test stage to an industrially applicable process. PER has been demonstrated on a relevant lightweight component in a robotic-based industrial-like joining cell for hybrid joining in combination with adhesive bonding. The feeding system for the plug was developed. It needs some modification in order to be introduced into serial production. Process parameters and a simplified calculation model have been developed.
Expected results and effects
The most important result is that we have been able to demonstrate an efficient and safe process for serial production with hybrid joining of materials that cannot be joined with conventional riveting. With the developed joining process, it should be easy to see how PER can be introduced in series production. When there is an industrial application for serial production, the last steps can be taken. Our hope is that PER will be used within a few years to solve challenging joining concepts. PER opens new opportunities to design and join future lightweight constructions with mixed materials.
Planned approach and implementation
The project group was well balanced with expertise from equipment and materials suppliers together with OEM, college and institute. The various activities have been coordinated at 12 project meetings, in addition to working meetings and other contacts. Process parameters have been evaluated in the hybrid joining cell at RISE IVF, where the industrial process was also demonstrated. Much work and evaluation has also been carried out at Volvo Cars in Olofström and Gothenburg. The feeding system was developed by ESSVE. HiS and Volvo have contributed input to the simulation model from IVF.
