In direct process comparison  of a compressor housing cast in gravity casting and low-pressure casting, significant advantages of the Kurtz low pressure technology become obvious. Benefit from our experience - we will be happy to discuss your project!

Advantages of Kurtz low-pressure technology:


  • Extremely reduced cycle material

  • Considerably lower costs for cleaning, rework,
    and re-melting of returns

  • Increase in output (more reproducible process,
    more independent of external influences)

  • Enormous flexibility in casting and feeding of parts
