Product Description

Silicon nitride is an important industrial ceramic material . It is a kind of super hard material, which has lubricity and wear resistance.Due to these excellent characteristics , silicon nitride are widely used for non-ferrous metal foundry industry eg,silicon nitride riser tube .

Silicon nitride riser tube is the key part of the low pressure casting machine for casting the aluminum alloy products(especially the products of the automobile and the motorbike ).In aluminum low pressure die casting process ,used for dosing and conveying of molten aluminum .In low pressure die casting process ,molten aluminum is transported by pressure from holding furnace through riser tube into a mould every 3-5 minutes .

Silicon nitride Riser tube made by Taisheng have excellent characteristics are as following :

1.High strength & good compactness

2.Low thermal expansion coefficient

3.Excellent thermal shock resistance

4.Low wetting by molten aluminum and non-ferrous melts.
