IFGL Refractories

Foundry

IFGL provides innovative solutions and technical ceramics products related to the foundry industry, and is the specialist in the field of mold filling and solidification.

With more than seventy years of experience our group company Hofmann Ceramic GmbH support customers in calculating, designing, constructing, and simulating casting systems. We use precise simulation software to analyze casting systems in order to discover potential areas of improvement during mold filling and solidification and optimize the casting system early on in the development phase. This lets our customers benefit from shorter development times and lower costs, as well as consistent product and process quality.

Round Hole Filters

Pressed ceramic round hole filters are produced with Hofmann’s proprietary dry press process, the only one of its kind in the world.

Features :

  1. Reproducible mold filling with consistent cross-sections of flow
  2. Precise filter fit with exact installation dimensions
  3. We can manufacture a suitable filter geometry for any application
  4. Well-calibrated casting systems help to achieve the best possible filtration results

HIPERCAST®

Hipercast is a high performance mullite-based highly durable ceramic filter for steel and heavy casting applications.

Features :

  1. Pressed thicknesses up to 40 mm
  2. Good thermo-mechanical properties with high fracture resistance.
  3. Casting temperatures up to 1750°C
  4. Flow quantities up to 15 t gray cast iron and up to 9 t spheroidal graphite iron per filter

EXHOF feeder heads

Hofmann Exothermic feeder heads have low fluorine and low sulfur composition and inorganic binding systems which significantly reduce smoke production.
Our development team work on new feeder head geometries that will offer solutions for complex customer requirements.

Features :

  1.  Guarantee high suction capabilities
  2. Low feeder head height suitable for narrow areas
  3. Don’t require breaker cores
  4. Outstanding mold seal under the feeder head neck
  5. Suitable for all molding lines
  6. Non-hygroscopic
  7. Excellent joint formation with low space requirements
  8. Available in all sizes

SiC-DC casting

DC casting solutions gives consistent joint properties on high-stress areas of cast parts and reduce heat moderately to avoid cast deterioration.

Features : 

  1. Prevents undesirable hard peripheral zones
  2. Homogeneous joint formation in the operating area
  3. Prevents cavitation and blisters
  4. Available in all sizes and shapes
  5. Lower processing costs
