Ceramic Sagger

Refractory Sagger

The Ceramic Sagger / Ceramic Setter Plate offers an all in one solution for firing of either components or powders. These saggers can be stacked directly on top of each other at Temperatures up to 1650 C. Reduced wall thickness over traditional high alumina or mullite refractory saggers can lead to increased product loading, further weight reduction, decreased cycle time.

 

We producce saggers for the application of temperature range up to 1750°C. We coordinate the respective sagger type and quality with our customers, depending on the chemical, thermal and geometric requirements.Our long years of experience in manufacturing saggers guarantees long service lives and high-speed heating cycles.

 

 

Applications:

 

1.For firing of heavy loads pressed mullite and mullite-alumina plates have excellent resistance to sagging. Engineered compositions make smooth and flat surfaces possible while maintaining excellent thermal shock properties. 

 

2.For small parts firing, Innovacera offers machinable, low mass alumina fiber based compositions that eliminate the need for costly hard tooling. This allows manufacturers to customize setter configuration without costly mold charges. Low mass setters exhibit excellent thermal shock properties and by reducing the mass of the overall furnace load. This enables rapid furnace turnaround for firing parts that can withstand rapid cooling rates.
