We provide an optimal casting quality

All castings send to the receiver have quality certificate. Care about quality and staying a reliable supplier is our main goal. We provide comprehensive testing of casting materials and finished products:

  1. iron's chemical composition analysis with emission spectrometer
  2. casting process control
  3. examination of castings quality:
    - chemical composition
    - strength and hardness
    - measurements and castings surface
    - examination of the castings microstructure
