Question

How do we detect the quality of the wire drawing die?

Answer 1

detect following information: dimensional tolerances (including out-of-roundness), finish, concentricity (with specifications below 0.4mm), and transition zones. For the dimensional tolerance of the test method, soft lead or copper wire is used as the lead wire, and the outer diameter is measured by the micrometer. The smoothness and the low-level magnifying mirror are checked in each transition zone. more in wococarbide. The concentricity is directly drawn by the steel wire and the flatness is checked.
