Sample Solutions

Solutions - CAD portal

CAD portal

Our components from high-performance ceramics can also be configured on-line. All product variants are stored in our CAD portal - you can make adjustments quickly and easily by entering the parameters for your welding process.

Solutions - Slide rings

Slide rings

Slide rings and mating rings are the two main components of a slide-ring seal. The slide ring and mating ring are in constant contact. However, they do not touch one another but slide over each other.

Solutions - Bobbin cores

Bobbin cores

Bobbin cores are usually round parts with a large groove into which a copper coil is wound. This coil induces a magnetic field in the centre of the coil.

Solutions - Vacuum-tight components

Vacuum-tight components

Many technical processes such as semiconductor fabrication, medical technology or material testing are conducted in a vacuum.

Solutions - Dosing components

Dosing components

The dosing systems used in the field of dosing technology are being continuously optimized and advanced.

Solutions - Flow measurement

Flow measurement

One of the most important variables in industrial measurement technology alongside temperature, pressure and force is flow measurement, which is one of the fundamentals of process automation.

Solutions - Punching stamps

Punching stamps

Punching stamps must repeatedly punch a contour in a predetermined geometry into a sheet.

Solutions - Goods carriers

Goods carriers

Goods carriers are used to hold other products, such as circuit boards. In many cases, they must be electrically insulating, wear-resistant and designed to cope with thermal shock to enable smooth handling.

Solutions - Heat insulation board

Heat insulation board

DOTHERM and ISOCOS offer heat protection plates that are precisely adapted to the respective process requirements in terms of material, compression strength, temperature resistance and dimensional stability.
