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.
Gas nozzles
Ceramic gas nozzles made from silicon nitride are characterised by exceptionally long service lives. In certain applications, the ceramic actually prevents the adhesion of weld spatter.
Punching stamps
Punching stamps must repeatedly punch a contour in a predetermined geometry into a sheet.
