SEDEX foundry filters have been used by the foundry industry for more than 25 years. During this time, the filter and its application have been continuously improved in co-operation with leading foundries around the world. The use of SEDEX foundry filters is a guaranteed way to produce quality, cost effective castings. For these reasons the use of SEDEX has become state-of-the-art in many foundries. The most used foundry filter world wide is the confirmation of the ability of SEDEX to fulfil customer demands. Success builds trust.

The application of SEDEX foundry filters for the production of the most demanding castings ensures that the full mechanical and dynamic properties of the casting alloy can be achieved. The use of conventional gating systems, even with generously dimensioned runner bars, is not sufficient to retain enough slag and suspended reaction products to meet
the high quality standards of today‘s castings. These demands can be readily and consistently achieved with the help of SEDEX foundry filters.
