High quality Aluminium Titanate Sprue Bushing Cup

Specifications

STA Aluminium Titanate Sprue Bushings, sprue cup, spure bush.

All components made from aluminium titanate are manufactured according to the customers'demands. Due to its material properties, aluminium titanate is a very good choice for components like riser tubes, dosing tubes for pressure die casting furnaces as well as sprue bushes for low pressure die casting.Especially sprue bushings made from aluminium titanate have several advantages over the commonly used steel-type sprue bushes. Because of the better insulation properties, it is widely used in the area of gate system.

Nozzles/Bushes as an insert or as a joint to the mould

Spouts, Nozzles, Stoppers/Plugs and Sliding Plates for the flow control of molten masses.

Aluminium Titanate Riser Tube or aluminium titanate Stalk Tube

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 .

Characteristics:

Excellent thermal shock resistance

No infiltration with the non-ferrous metal

Excellent wear resistance

Low thermal-expansion coefficient

The service life of the aluminum titanate riser tube can reach 60 days 

Application:

Aluminum Titanate riser tube / stalk tube can be used for the conveying , dosing of non-ferrous metal melts, especially for low pressure die casting of aluminium. The products can keep the purity of low pressure die casting products , and provide for the casting plants with high quality .

The aluminum titanate has higher melting point(1860°C±10°C),lower thermal expansion coefficient(RT—1000°C,α<2.0×10-6/°C) and excellent heat-shock resistance. Besides, the aluminum titanate don’t infiltrate with the metal melt(especially the non-ferrous metals) and glass melt. Therefore aluminum titanate can be widely used in the conditions of high-temperature resistance, heat-shock resistance and corrision resistance.

Riser tube Application:

    Aluminum Titanate riser tube made STA .ltd is used to transfer the molten aluminum from the Low pressure casting furnace to the wheel mould.
