NANO Diamond Coated Die For Wire

Bore size: 0.3 MM -45 MM

Production method: Using hard alloy as the substrate, the hole pattern is designed according to the drawing conditions, and then the processed mold is placed in a dedicated HFCVD vacuum furnace. Tantalum wire is passed through the mold hole, filled with a certain proportion of hydrogen and methane mixed gas, heated by electricity, and maintained at a specific pressure. A layer of diamond is vapor deposited in the mold hole, and then the mold is subjected to secondary processing and grinding to form a nano-sized diamond coating drawing mold.

Characteristics: Nano coated diamond molds have the characteristics of diamond, high hardness, good wear resistance, good compressive and tensile strength, and low friction coefficient.

Usage characteristics: Suitable for wet and dry pulling. The mold has a long service life, which is more than 20-30 times that of ordinary hard alloys and 5 to 10 times that of PCD molds. When the mold is scrapped, the aperture changes very little, the working surface smoothness is high, and the dimensional accuracy is high.

Superior cost-effectiveness: The improvement of mold wear resistance can greatly enhance equipment efficiency and increase drawing speed; The mold has a long service life and does not require frequent replacement, greatly improving production efficiency and saving raw materials; Improve product quality; Save labor; Save electricity.  

Application:

Copper wire, aluminum wire, wire and cable, welding wire, low/ medium/high carbon steel wire, stainless steel wire, low/medium/high carbon steel wire, etc.
