Vacuum-tight components - MOESCHTER Group GmbH

Many technical processes such as semiconductor fabrication, medical technology or material testing are conducted in a vacuum. A high level of vacuum-tightness is a key requirement for many of the components used in these processes. In addition, the materials used must not degas in a vacuum.

DOCERAM high-performance ceramics, such as aluminium oxide, CERAZUR and VOLCERA, are ideally suited to these types of processes. Their densely sintered structure allows them to be used in ultra-high vacuums.

Sample applications include components made of high-performance ceramics that are used as insulators and mountings in coating processes.

Latest applications

Applications - Picking

Picking

In manufacturing and processing companies, components are picked and held in position in the different processing steps.

Applications - Sealing

Sealing

Pumps are indispensable components of many industrial processes used in plant operations. The unexpected failure of bearings and the occurrence of leaks due to failed seals lead to downtimes, high outage costs and major safety risks - especially if…

Applications - Fixing

Fixing

In an engineering context, fixing something means keeping a component in its intended position at all times, either cyclically or permanently.

Applications - Guiding

Guiding

Guiding means keeping something in position and is therefore roughly equivalent to positioning, directing and deflecting. For instance, lateral guide gibs can be used to deflect components on a conveyor belt in order to reposition them.

Applications - Positioning

Positioning

Positioning elements made from high-performance ceramics are used at various points in car manufacturing, including in car body construction.
