SiC-DC casting

hofmann CERAMiC has been producing DC casting solutions from silicon carbide since the 1950s. Our DC casting solutions make a great choice if you need consistent joint properties on high-stress areas of cast parts and need to reduce heat moderately to avoid cast deterioration. We achieve this through combining the composition of the casting compound, with our manufacturing technology.

SiC – DC casting by hofmann CERAMiC …

  • prevents undesirable hard peripheral zones
  • promotes homogeneous joint formation in the operating area
  • prevents buildup of condensate
    → results in a cleaner cast surface
  • prevents cavitation and blisters
  • lowers processing costs
  • available in all sizes and shapes

HIPERCAST®

With the development of a new high performance mullite-based ceramic with the type designation HIPERCAST®, hofmann CERAMiC has created an extraordinary dry-pressed filter. HIPERCAST® allows us to achieve performance values previously considered unattainable for individual filters.

This opens up whole new possibilities in the area of foundry manufacturing technology.

  • Pressed thicknesses up to 40 mm
  • Thermo-mechanical qualities offer great capacity reserves with regard to fracture resistance.
  • High savings potential for return materials and sand
  • Casting temperatures up to 1750°C can be handled with no issues
  • Flow quantities up to 15 t gray cast iron and up to 9 t spheroidal graphite iron per filter
    → actual stress limit unknown, since our tests have never been able to destroy a filter!

round hole filters

Our pressed ceramic round hole filters are produced in our proprietary dry press process, the only one of its kind in the world, and stand out by offering the following properties:

  • hydraulic properties can be calculated more precisely thanks to the exact geometry
    → reproducible mold filling with consistent cross-sections of flow
    → precise filter fit with exact installation dimensions
  • we can manufacture a suitable filter geometry for any application
  • well-calibrated casting systems help us achieve the best possible filtration results
