Blue Ridge Metals has a variety of wire drawing machines to meet our customer needs. But when it is imperative that the wire be certifiably free of surface defects, Blue Ridge Metals offers a rigorous quality assurance system. Our wire draw eddy current machines examines wire in its prefabricated stage and identifies detrimental surface flaws to a minimum of 0.10mm (0.004 inches). The defect material is marked in such a way that the defective locations can be identified with paint spray markings. Marked material can then be split or rejected during the cold-forming process.
Eddy Current Testing
In some cases the surface can be corrected through the use of wire peeling. The wire peeling process is designed to eliminate seams, surface defects and imperfections such as mill flaws, scratches and decarburization.
