Ceramic seal and regulator technology has a positive impact on the productivity, dependability, aging characteristics and operating costs of industrial equipment and household appliances.
“Conventional materials often fail to perform under operating conditions marked by aggressive environments, high pressure and high temperatures.”
CeramTec offers a broad spectrum of materials to create the technical ceramics used in manufacturing appliances and other consumer goods. Alumina can be used whenever insulation is required, whereas silicon carbide excels in thermal conductivity and silicon nitride provides strength and durability. In instances where expansion coefficients are key, zirconium oxide is the material of choice.
What all of these ceramic materials have in common is their unsurpassed wear resistance and chemical resistance to aggressive media that flow through components at high temperatures and under high pressure. This means that components made from these materials satisfy even the most stringent requirements when it comes to functionality, long service life and cost effectiveness in equipment and mechanical engineering.
“Chemical resistance, efficiency with gas-tight seals and diamond-like hardness are compelling arguments for using ceramics in seal and regulator technology.”
Under ideal circumstances components can be axially demolded, making it possible to use the affordable pressed disk method of production. CeramTec can also manufacture more complex molds using injection molding. Grinding, polishing and rotofinishing are some of the mechanical finishing options available for ensuring tight tolerances and improving surface finish quality.
Bearings, seals, regulator discs and seal rings made from technical ceramics are the first choice for every pump used in household appliances and electrical appliances – including washing machines and dishwashers. But no matter what areas of household appliance engineering, mechanical engineering, pharmaceuticals or the food and beverage industry, and no matter what the variety of different media used: discharging, pumping, regulating, controlling, measuring, grinding, blocking, sealing, compressing, insulating or mixing – ceramic components help increase service life, expand applications, lower operating costs and develop new market segments for products.
