3M and DSM to meet with lightweight construction experts
The new lightweight design material combination for applications in the entire powertrain, which was first presented at the end of 2012, opens up new possibilities for more energy and weight-efficient vehicles. It is manufactured using two high-performance materials - Stanyl polyamide 46 from DSM and Fluoroelastomers from Dyneon, a subsidiary of multi-technology company 3M - in an economical two-component injection moulding process.
Besides the significantly reduced weight in comparison with the metal components traditionally used, the two-stage manufacturing process provides further economic and environmental advantages. The cycle time for the process is a mere two to three minutes per component. Including the vulcanisation and curing process, the components are ready for installation after just two hours. Moreover, auxiliary materials are no longer required, thus eliminating the costs for the purchase and disposal of these. Both components afford excellent mechanical stability, can withstand high temperatures even for extended periods, and are resistant to the chemical impact of aggressive media such as oil and fuels.
This makes the new material combination ideal for components such as crankcases, seals and gaskets, both dynamic and static. In addition, this innovation provides more freedom for new construction designs and assembly techniques as well as the integration of functions.
