    Automotive Industry

    Piezoceramic sensors act as sensors for electronic controls and provide them with information about engine smoothness, position and direction changes of the vehicle. Electronic components based on ceramic substrates react to this information and regulate the engine management, safety systems, such as ABS and ASR, and release the airbag if necessary. In the engine area, heat-resistant ceramic parts, such as valve components, crankshaft support bodies, components for water and fuel pumps, ensure higher efficiency, less wear and lower noise. As a composite material, ceramic-metal composites open up new prospects in lightweight metal construction. Last but not least, modern halogen, xenon or LED lighting systems with ceramic components significantly improve visibility. And ceramic armor for ballistic vehicle protection provide the necessary safety of emergency vehicles. The use of ceramic cutting materials and precision tools in automobile production serves to efficiently produce vehicle components made of cast iron or hardened steels.
  • Welding Application

    Welding Application

    For the welding process, UNIPRETEC supplies advanced ceramics as the ideal materials for welding tools such as welding rollers, welding centering pins or gas nozzles. Parts made of advanced ceramics are with particular hardness and wear resistance, very high temperature resistance and chemical resistance. They enable a multiplied service life, shorten the overall set-up times, extend the machine running times and improve the quality of the end product. In other words, advanced ceramics in the welding process create added value. ▼ Silicon Nitride Weld Rollers for HP ERW Electric resistance welding (ERW) encompasses a range of joining techniques where faying surfaces are heated to the point of fusion via electrical resistance. This high-temperature process is mechanically intensive, requiring extremely strong and wear resistant materials that can withstand severe thermal shock. Although stainless steel welding rollers will provide significant improvements in terms of precision, they will fail due to thermal and mechanical breakdown far quicker than silicon nitride. The electrical conductivity of stainless steel welding rollers can also be problematic, contributing to material pick-up problems that are commonplace in non-ferrous metal joining. Silicon nitride welding rollers vastly outperform steel alternatives, with significantly improved thermal shock resistance and strength, notwithstanding the material’s non-conductivity. Silicon nitride ceramic material from UNIPRETEC features a compressive strength of up to 3,500 MPa and a thermal shock resistance of Δ900°C. This exceeds the requirements for seam welding, providing a number of advantages over conventional welding rollers, including better product quality, fewer weld failures, reduced roller maintenance requirements, and reduced cooling times. Subsequently, silicon nitride welding rollers can reduce HF-ERW power by up to 30% and can outperform steel components by a factor of up to 10x.

    Semiconductor Industry

    The technical advanced ceramics offer considerable advantages against metal and plastic. They maintain their dimensional stability in the high temperature range (> 1000 ° C). They are excellent electrical insulators. They show high wear resistance and do not degas under vacuum. In addition, the technical advanced ceramics are inert materials and corrosion resistant to gas, acid and plasma environment. Therefore, the ceramics are important materials in the wafer treatment process. UNIPRETEC offers various ceramic components for semiconductor industry.
