The channel systems in castings have become increasingly complex, which makes their testing extremely difficult and sophisticated. One can select the appropriate testing technology depending on the design of the individual castings and channels, which can be visible light, infra radiation or gas-based. This latter, our so-called GasStream solution is also suitable for the testing of full or partial blockages of parallel channels. The GasStream solution is patented.


  • testing based on visible light
  • testing based on infra radiation
  • gas-based testing (GasStream)
  • inline or offline design
  • a stand-alone application or may be integrated into QualiLine-C


  • detection of lack of channels owing to sand-core cracking
  • detection of partial or full blockage owing to sand-core cracking
  • detection of residual sand-core in the channel

Our systems in operation

  • an infra device that tests the channels of four- and six-cylinder castings
  • LightStream solutions integrated into QualiLine-C machines
  • GasStream inspection systems built into production lines
