As a producer of black or bright metal bars, you are confronted with customer demands for high quality products - and for good reason, since semi-finished products are often used in safety critical parts for public transport, automobiles, construction, etc.
The NOVAFLUX flux leakage system can help you find cracks reliably and reduce scrap and material expenses effectively. It detects cracks as small as 0.1 mm in depth.
