DuPont Shows How Collaboration Generates Better Performance, Lower Cost

19.10.2012
DuPont Performance Polymers is featuring an innovative automotive jounce bumper component to show how design, materials and processing can converge to deliver added performance and lower cost.
The featured jounce bumper is part of a vehicle’s shock-absorber system designed to absorb impact and dampen noise, vibration and harshness (NVH).

DuPont, working with a team from Ossberger, capitalized on the flexibility attributes of DuPont™ Hytrel® thermoplastic elastomer and a unique Ossberger blow-molding technology to simplify the component from four pieces that require subassembly to a single piece. This alone significantly reduced cost, size and improved performance.

The featured jounce bumper is part of a vehicle’s shock-absorber system designed to absorb impact and dampen noise, vibration and harshness (NVH).

“Materials are critical in component design and the best results happen when the three primary phases in product development – design, materials and processing - converge,” said Patrick Cazuc, Automotive Director Europe, DuPont Performance Polymers.

Beyond Materials

In developing this component, DuPont worked on design, using non-linear Finite Element Analysis (FEA) techniques and specialist software, as well as processing, including rapid prototyping and laboratory testing at the DuPont European Technical Centre. By using an Ossberger machine, the thickness profile was tightly controlled, facilitating optimum energy-absorbing properties with a maximum compression ratio.
Proven Performance

These jounce bumpers made of Hytrel® have been tested by automakers on a variety of vehicles over tens of thousands of kilometres. According to an independent vehicle testing institute: "Jounce Bumpers of Hytrel® bring higher comfort and steering feedback, together with better road handling compared to PU (polyurethane) parts. Wheel rebound is also reduced with higher attenuation of low impacts. The front axis roll angle is also reduced."

“The new Jounce Bumper is an example of DuPont listening to market needs and developing a superior solution, while providing all the necessary collaborative support needed to bring an idea from design to commercialisation,” Cazuc concludes. “More to come on this new development.”

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...

Im Focus: Transparent - Flexible - Printable: Key technologies for tomorrow’s displays

The trend-forward world of display technology relies on innovative materials and novel approaches to steadily advance the visual experience, for example through higher pixel densities, better contrast, larger formats or user-friendler design. Fraunhofer ISC’s newly developed materials for optics and electronics now broaden the application potential of next generation displays. Learn about lower cost-effective wet-chemical printing procedures and the new materials at the Fraunhofer ISC booth # 1021 in North Hall D during the SID International Symposium on Information Display held from 22 to 27 May 2016 at San Francisco’s Moscone Center.
