Piezo-ceramic components act as sensors for electronic controls and provide them with information on the vehicle’s quiet engine operation, position and changes in direction. Electronic components based on ceramic substrates react to this information and control motor management, safety systems like ABS and ASR and release the airbag when necessary. In engines heat-resistant ceramic parts like valve components, backings in the crankshaft housing and components for water and fuel pumps ensure increased efficiency, less wear and lower noise emission. Ceramic-metal composites open up a world of new possibilities in light metal construction. Not least, modern halogen, xenon or LED light systems with ceramic components significantly improve visibility, and ceramic armor components designed for ballistic vehicle protection deliver the required safety for military and emergency vehicles. The use of SPK® ceramic cutting materials and precision tools in automotive manufacturing ensures the efficient production of vehicle components made of cast iron or hardened steels.
