Foundry technology
Round hole filter
Our pressed ceramic round hole filters are produced using a unique dry pressing process developed in-house and are characterized by the following properties:
- hydraulic properties are more precisely calculable due to the exact geometry
- reproducible mold filling due to consistent flow cross-sections
- precise filter seat due to exact installation dimensions
- a suitable filter geometry can be produced for every application
- filtration results at the highest level are achieved with properly tuned casting systems
- available in round, square or rectangular shapes
The right filter for every challenge!

Exothermic EXHOF-L feeders
To meet our commitment to environmentally conscious action, we offer our customers highly exothermic feeders. In addition to a low-fluorine and low-sulfur composition, our feeders are characterized by significantly reduced smoke emissions due to the modern, inorganic binder system.
- environmentally friendly, low-smoke formulation
- also available with low fluorine or fluorine-free on request
- available in all sizes and shapes
- highest performance with consistent quality
- transparent and traceable documentation of all feeder batches
The right feeder for every application!

SiC chill molds
Our chill molds are always used when uniform structural properties are required in highly stressed cast part areas where the necessary heat must be moderately extracted to avoid casting degeneration. This is achieved through the composition of the mass in combination with the manufacturing technology used.
- prevent undesirable hard edge zones
- reduce machining costs
- promote homogeneous microstructure formation in the effective area
- available in various sizes and shapes
- reusable
