Practical application proves that silicon nitride ceramic SG-28 is very suitable for the riser tube & stalk of low-pressure casting;
Compared with commonly used cast iron, aluminum titanate, silicon carbide and other materials, silicon nitride ceramic has the best thermal shock resistance and a service life of more than one year;
Due to the low wettability to aluminum liquid,it reduces the slagging of the inner and outer walls of the riser tube & stalk, which is convenient for daily maintenance;
Silicon nitride ceramic S-28 has excellent corrosion resistance, which can reduce the pollution of aluminum liquid, therefore, it will be beneficial to improve the quality of casting for customers.

Zhejiang Shangguijuli Special Material Technology Co., Ltd. is a leading manufacturer specializing in R&D and production of high-performance silicon nitride ceramic material in China.
