Quality Inspection
★ Flaw Detection
Corresponding tests for each process of Tungsten wire. Under flaw detection, there are Grade A (2 crack points per 100 meters), B, C Grade. The more cracks, the more easily the filaments are broken during processing. We will choose different standard according different request for quality grade.
★ Equipment
A rolling mill introduced from Germany, which it can be deeply process the rod core, which can make the inside struction more uniform. Unlike the early traditional technology, are mainly surface processing.
★ Property
Online measuring device in the wire drawing process, which can monitor the overall diameter uniformity..
