PROPERTIES

Round hole filters made of aluminium silicate ceramics with mullite as the main component are used for casting aluminium and its alloys as well as for iron casting. Higher-quality filters made of corundum-mullite ceramic with an aluminium oxide content of over 70 % are the right choice for steel casting and are widely used. In our range you will find pressed ceramic round hole filters with round, rectangular and square outer contours. The filters are characterised in particular by a precise geometry, which thus ensures an optimum flow result, and a particularly high temperature resistance of up to 1700 °C. A variety of types are available depending on the flow rate, casting speed and filter capacity.

Filters are always installed as close as possible to the casting after the sprue system and before the gate. The resulting laminar flow is important for high quality cast products. Ideally, the filter is installed vertically in a horizontal duct. A reservoir is formed in front of the filter, which is used to absorb the impurities and to homogenize the material and the temperature.
