Lower coefficient of thermal expansion
Excellent thermal shock resistance
No infiltration with molten aluminum and other non-ferrous metal molten
In the equipment used in the production of cast aluminum alloy wheels, aluminum rod casting, slab casting, and aluminum alloy casting, it is necessary to use ceramic sprue sleeve bushing to form part of the low-pressure runner.
In the casting process, traditional metal sprue bushings have disadvantages such as inability to resist corrosion, fast heat conduction, difficulty in adjusting the casting process and large fluctuations, and are greatly affected by the environment and the temperature of the raw materials. Ceramic aluminum titanate sprue sleeve bushing has the advantages of corrosion resistance, strong heat preservation, high temperature resistance, etc., which effectively guarantees the temperature of the feeding channel, the production efficiency is significantly improved, and the quality of castings is significantly improved. The weight of waste solidified in the riser is only half of that of traditional metal materials.
