ASK Chemicals Bendorf branch is located Bendorf / Rhein / Germany is manufacturing and supplying filters and feeding systems to the foundry industry.
The portfolio comprises a considerably wide and innovative range of inorganic and cold-box bonded, highly exothermic, or isolating risers that are available in fluorine-free or low-fluorine versions.

The mini-risers are available with rigid pins or spring pins and therefore they are suited to different applications on various molding lines and in various different molding processes.

The portfolio is rounded off by ceramic foam filters and pressed filters that are optimally adapted to the respective material or molding process.

The simulation of the casting process provides foundries with relevant information for the optimization of gating and feeding systems. In-gate-systems, riser geometries and positioning of the risers are optimally adapted.
