Important Criteria’s of A Dies for Drawing Wire

In finishing process of metal wire production, wire diameter shall be determined by dies hole. Conventional dies are carbide wiring drawing dies. Those have demerits of short lifetime. Our diamond wiring drawing dies have attracted manufacturers’ attention due to their long lifetime. Materials in dies hole are mono-crystal or sintered diamonds that are most hardest materials altogether materials on the world. Sintered diamond, is also called because the polycrystalline diamonds, is produced in burning process with metal binder.

Concerning dies in natural diamond, the stones need to be selected consistent with precise criteria’s (weight, purity, tension and stress…) so as to best withstand the pressures of the wire drawing process and to maximize the quantity of republishing which will be done. Concerning polycrystalline dies (PCD), the selection of suppliers for these blanks is important so as to realize the simplest balance between surface fi nish and longevity. PCD blanks are regularly tested before being approved.

Respect and repeatability of the geometry

The required geometry must be achieved and be identical from one die set to subsequent for multiline machines. This reduces the risks of early wear and wire breakages.

Profi l blend

The junction between angle changes within the die got to be smoothed out and blended together, thus eliminating sharp angles. this may avoid the creation of metal dust and swarf which might contaminate the lubricant baths.

Polishing

A polishing of quality (mirror fi nish) allows to scale back stress and defects on the wire during the drawing process. Polishing quality will determine the wire surface fi nish and is important for the fi nishing dies during a set.

Mounting powder

The mounting powder, during which the diamond is inserted, must be robust and even have properties to get rid of heat generated by drawing. it's decisive to urge the simplest die’s lifespan.

There are some sorts of wire drawing dies made by diamond, and therefore the important point that determines coiling efficiency could also be mounting method of diamond into base materials. We use the high-level technologies of mounting diamond with super-hard metal, so these dies get the drawing wire length up to 1.5?3.0 time, and dies lifetime up to three times as compared with the opposite Diamond wire drawing dies. Our sintered Diamond wire drawing dies are often applied to thicker diameter wire, and circularity error are often minimized due to no directivity in crystal.
