Volcera is a silicon nitride and is characterised by a range of properties that make it a very interesting choice for industrial applications. Thanks to its high strength and low thermal expansion coefficient, the Volcera material is ideally suited to alternating thermal stresses.

Even at temperatures of around 1,000 °C, components made from Volcera can still transmit very high forces and is therefore extremely well suited to soldering and welding applications.

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 - 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 - Blank holders

Blank holders

Blank holders serve to hold components securely in position in the application. They are typically held against a surface/contour.

Solutions - Welding device

Welding device - ModulMaster

Welding devices hold two or more (car body) components in position so that they can then be permanently joined together.

Solutions - Sensor protection

Sensor protection

Examples of sensor protection include wear caps, wear disks or wear plates, which are used to protect the sensor behind.

Solutions - Punching stamps

Punching stamps

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

Solutions - Idler pulley

Forming rollers

Forming processes place very high demands on the wear resistance and stability of the tools and mountings used. High surface qualities are required.

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 - Non-material-specific insulation solution

Non-material-specific insulation solutions

In many industrial applications, it makes sense to use multi-layered materials or material combinations.

Solutions - Workpiece carriers

Workpiece holder/carrier

The exact positioning of components is particularly important for series production. Here, multiple components are frequently welded, bonded, riveted, soldered, etc. at high cycle rates to form assemblies.

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.
