Silicon Nitride Components | Hardware Parts 
Ruihong's silicon nitride components, in the high temperature and high pressure working environment of aluminum casting, not only can maintain good mechanical strength and heat conduction properties, but also they do not react with aluminum liquid, do not stick to aluminum slag, and have extremely excellent heat shock, wear and corrosion resistance. It can replace imported products from Japan and has a higher cost performance. We are confident that our products will minimize molten aluminum liquid impurity pollution, while the service life in hot and cold chamber aluminum casting equipment is longer, so as to help you produce higher quality aluminum castings, improve production efficiency, and for you to significantly reduce labor maintenance costs, increase profits.
