Sample Solutions
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.
Dosing components
The dosing systems used in the field of dosing technology are being continuously optimized and advanced.
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.
Blank holders
Blank holders serve to hold components securely in position in the application. They are typically held against a surface/contour.
Sensor protection
Examples of sensor protection include wear caps, wear disks or wear plates, which are used to protect the sensor behind.
Punching stamps
Punching stamps must repeatedly punch a contour in a predetermined geometry into a sheet.
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.
Vacuum-tight components
Many technical processes such as semiconductor fabrication, medical technology or material testing are conducted in a vacuum.
Non-material-specific insulation solutions
In many industrial applications, it makes sense to use multi-layered materials or material combinations.
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.
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.
