Silicon Nitride Si3N4 Ceramic Riser Tube For Aluminum Processing Industry

The excellent oxidation resistance, thermal shock stability, and non-wettability to molten metals such as aluminum make silicon nitride (Si3N4) ceramic riser tubes an ideal material for the low-pressure casting industry. They are primarily used in low-pressure casting machines for aluminum alloy products, particularly in the casting of automotive, motorcycle wheels, and other components.

The use of silicon nitride ceramic riser tubes not only improves casting quality but also significantly reduces the operating costs of low-pressure casting. Their service life is 5 to 20 times longer than traditional riser tubes, which greatly reduces the frequency of replacements, ensuring continuous and automated production.

With years of experience in advanced ceramic production, Mascera has developed a high-quality, high-performance silicon nitride ceramic riser tube production system and has been supplying these tubes in large quantities. We can produce riser tubes in various specifications according to customer drawings and look forward to collaborating for mutual success.
