(2) The strength at normal temperature and high temperature is high, one of the functions of the sagger is load bearing, and the strength of the sagger must withstand the load of the product and the sagger. (3) Good thermal conductivity and low heat storage property.
The sagger is usually produced by using mullite, cordierite, magnesia alumina spinel and the like as main raw materials. Because the granularity of the raw materials is different and the hardness is higher, when the conventional hydraulic press metal die forming method is adopted for production, the die and the materials move relatively to generate friction, so that the die abrasion is caused to a higher degree. When the abrasion of the die reaches a certain degree, the surface quality and the dimensional accuracy of the machined workpiece are seriously affected.

In actual production, multiple sets of molds are often backed up with each other, and the effectiveness of the molds is low. There is an industry to develop isostatic pressing mold to improve the wear resistance of the mold, but the use of isostatic pressing method requires the use of expensive isostatic pressing equipment and the cost investment is high.
It can thus be seen that there is a need for further improvements in the art.
