At the same time, we introduce our new ultrasonic extrusion dies technology. The combination of this new sialon silicon nitride ceramic die and the ultrasonic technology will result in a up to 70% FASTER production compared to non-ultrasonic treatment.
Silicon Nitride ceramic extrusion dies are used for the extrusion and drawing of non-ferrous alloys in the metal extrusion industry.
With regards to Sialon ceramics, there is substitution of silicon by aluminum with corresponding atomic replacement of nitrogen by oxygen, to satisfy valency requirements.
The resulting ‘solution’ has superior properties to the original pure solvent, syalon, silicon nitride or Si3N4 extrusion dies.
Silicon Nitride ceramics have found extensive use in non-ferrous molten metal handling, particularly aluminum and its alloys, including metal feed tubes for aluminum die casting, burner and immersion heater tubes, injector and degassing for nonferrous metals, thermocouple protection tubes, crucibles and ladles.
