Introduction to CVD Diamond Coated Wire Drawing Dies

The super-hard CVD diamond coating has brought a revolutionary leap in the service life of dies. The CVD diamond coated wire drawing die uses a tungsten carbide die as the substrate. First, it undergoes a fine die repair process and a special pretreatment process. Subsequently, with the help of ultra-vacuum equipment, multiple layers of diamond films at the micron to nanometer level are coated. After coating, it is polished and sleeved to finally become a high-performance finished product.

Application Scope of CVD Diamond Coated Wire Drawing Dies

This wire drawing die has extremely wide applicability. It is suitable for the drawing operations of various gas-shielded welding wires, high-carbon steel wires, medium and low-carbon steel wires, stainless steel wires, copper-aluminum wires, and various special-shaped pipes and wires. It has no restrictions on the processed materials and can meet diverse production needs.

Performance and Characteristics of CVD Diamond Coated Wire Drawing Dies

Die Service Life and Physical and Chemical Properties of the Coating

It has an excellent die service life, and its coating has outstanding physical and chemical properties.

Die Characteristics

· Super-strong Film-Substrate Adhesion: The special pretreatment technology creates super-strong film-substrate adhesion, significantly extending the service life of the die.

· Extra-long Service Life: With its extra-long service life, it greatly reduces the die change frequency, reduces production interruptions, and improves production continuity.

· Ultra-fine Nanoscale Polished Surface: The surface polished at the ultra-fine nanoscale can effectively improve the quality of the wire, making the surface of the drawn product smoother and more delicate.

· High Drawing Speed: It can achieve ultra-high-speed drawing, increase the drawing speed, greatly improve production efficiency, and help enterprises increase production capacity.

· Simple Cooling Method: No special cooling device is required. Only water cooling can ensure the ultra-long service life of the die, reducing equipment costs.

· Ordinary Lubrication Requirements: No special lubricating medium is needed. Using a clean ordinary lubricating medium can ensure the long-term stable service of the die, simplifying the production process.
