silicon nitride ceramic riser tube for low pressure die casting
Riser tube is the key part of the low pressure casting machine for casting aluminum alloy products(such as aluminum wheels,other aluminum alloy products), In die casting process ,molten aluminum(700-900)is sent from riser tube to mould cavity evert 3-5 minutes .Silicon nitride Riser tube made by Taisheng have excellent corrosion resistance, low thermal-expansion coefficient ,its service life is 5-20 times longer than usual material , after using ,it can improve the quality of aluminum alloy products and reduced cost .
Applation:
Conveying of non ferrous matal melts
Advantages:
non-wetting property
