NANO Diamond Coated Die For Tube

Hole 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.

advantage:

High precision size control, stable size of wire and pipe, and long-term consistency of size.

The inner hole of the mold is bright, with good self-lubricating performance, low surface friction coefficient, smooth surface of the product, and can reduce equipment wear and tear.

By saving raw materials, the length of the products produced is much longer than the wire produced by traditional molds.

No maintenance mode, no need for maintenance, reduces downtime detection and mold replacement times, greatly improves production efficiency, and saves labor costs.
