Ceramic Sprue Bushings

201411282011131962Application:

They form the “entrance” to the mold in Low-Pressure-Casting Material:

Materials:

Aluminum Titanate: Al2TiO5

Advantage:

excellent thermal shock and corrosion resistance
low wettability with non-ferrous molten metals
low thermal conductivity

Sprue bushings made AT have very low wettability by molten aluminum, good chemical resistance and a very low thermal expansion. Therefore these kind of nozzles are very resistant to thermal cycling of several hundred degrees. The nozzles have excellent insulating properties which is highly advantageous in the area of the gate system.
