New technique for sealing automotive ECUs

The automotive industry is continuously demanding more economical solutions from its suppliers. Some suppliers respond by just cutting prices but Trelleborg’s approach is very different. It looks for innovative solutions and this offers its customers better value, especially in high-tech components.

Automotive electronics sector is growing

An important area of focus for Trelleborg Sealing Solutions is the growing automotive electronics sector. In 2004 the majority of controls on cars were mechanical, with less than 20 percent being electronic. By 2015, this is expected to shift to a 40 percent electronic and 60 percent mechanical split.

“A secure seal on an electronic control unit or ECU is vital,” says Marco Holst, Automotive Engineering Manager at Trelleborg Sealing Solutions in Stuttgart, Germany. “Failure can be a major safety issue, so the seal must be guaranteed to keep out moisture and any external media which may interfere with the electronic unit.”
