Silicon Nitride Riser Tube

Product Description

Silicon nitride riser tube is the key part of the low pressure casting. Â It is the ideal materials of the metallurgy industry because of excellent characteristics. After using, it can not only improve the quality of the casting products but also reduce the cost. The service life is 5- 20 times longer than the traditional tube, so the replacement of the riser tube is reduced and the continuous of the production is ensured.
