Riser tube for low pressure casting machine is one of important parts. The melting aluminium (with the temperature 700~900) is sent to mould cavity from riser tube by pressure every 3~5 minutes. This asks the riser tube to be resistant of high temperature and thermal shock, no-wetting by molten aluminium, good air tightness and long term resistance to thermal shock.

The features are as following:

1,Excellent thermal shock resistance

2,No infiltration with the non-ferrous metal

3,Excellent corrosion resistance

4,Low thermal-expansion coefficient

5,The service life of the aluminum titanate lift tube can reach 60 days , can enhance the production efficiency and reduce the cost.
