Sprue bush is also known as sprue cup and insulating sleeve. It is a part on the low pressure casting machine for a-lloy wheel and other similar casting. Sprue bush is used to form low pressure runner.

Aluminium titanate sprue bush has good corrosion resistance, strengh, airtightness and thermal shock resistance.

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.
