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.
A critical ceramic part between riser tuber and down mould.Bushing can make alloy liquid smoothly filling mould without inclusions and help exhaust in the cavity for avoid secondary oxide slag during casting.
Advantages:Excellent thermal shock resistance
No infiltration with non-ferrous melts
Excellent corrosion resistance
Insulating properties
Low thermal expansion
Service life:5-7days
Excellent thermal shock resistance
Application:aluminum casting
