Orodjarstvo Križaj

For more than four decades, Orodjarstvo Križaj has been at the forefront of small Slovenian companies in the field of manufacturing tools for aluminum die casting of the highest quality, including cutting tools. Since our founding in 1982, we have grown as a family business and evolved wisely, following industry trends while maintaining our commitment to excellence.

Core Competency

  • Production of die casting tools

    With a team of 12 dedicated professionals, we manufacture 35-40 high-precision molds each year. We're able to manufacture molds weighing up to 5 tons, either with single or multiple cavities.

  • In-house design

    With our mold design team, we develop custom die casting molds to meet your specific requirements. Whether it's new mold designs or repairing and improving existing molds, we're here to help.

  • Technological edge

    Every die casting tool we design is optimized through die casting simulations using Novacast software. For CAD, we rely on Creo software from PTC. Our material selection is flexible and adapts to your needs with certified materials and heat treatments.

  • State-of-the-art machinery

    Regular investments in state-of-the-art machinery, including the grand Hermle C400U 5-axis CNC machining center, ensure that we meet the highest standards of precision and quality.

Reputation Our reliability, in-depth knowledge and extensive experience have led to lasting partnerships with numerous satisfied clients. While we can only present a handful of completed projects on our website (for intellectual property reasons), our portfolio is far more extensive and includes all types of die casting tools of varying complexity.
