Sialon ladles

We manufacture all types of sialon ladles for automated high pressure die casting machines.

These ceramic ladles offer a superior service life compared to cast iron ladles, which means considerably less downtime for manufacturing.

Because of its strength and corrosion resistance, ceramic ladles has proven to be very effective in high pressure die casting machines.

With regards to Sialons, 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.

Silicon Nitride ceramics (such as Sialon ladles) 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 for high pressure diecasting machines.

Description

Sialon II ™ ladles (silicon nitride) are strong ladles for high pressure die casting machines and the best choice when it comes to non-wetting and mechanical strength properties.
