CVD Coated Carbide Draw Dies
We recommend our Multi-layer TiN/TiCN/TiC/TiN CVD coated carbide drawing dies. This multi-layer CVD coating has excellent bonding properties that make it a great choice for heavy load applications and longer runs. It will increase die life and reduces galling.
What Is CVD Coating?
Chemical Vapor Deposition (CVD) is an atmosphere-controlled process conducted at elevated temperatures (~1925° F) in a CVD reactor. During this process, thin-film coatings are formed as the result of reactions between various gaseous phases and the heated surface of the carbide within the CVD reactor. As different gases are transported through the reactor, distinct coating layers are formed on the tooling substrate. The final product of these reactions is a hard, wear-resistant coating that exhibits a chemical and metallurgical bond to the carbide. Generally speaking, CVD coating is sometimes referred to as a High Rockwell Lubricant with a high micro-hardness (2400-3400 HV), typically in excess of 80 HRc, and it typically exhibits a low coefficient of friction of 0.15 to 0.35. CVD is an additive process, with an average thickness of 0.006 mm – 0.009 mm, or 0.00024” to 0.00035”.

ROUND DRAWING DIE SPECIFICATIONS
The maximum I.D. size for industry standard round die inserts are only to be used as a general guide and may vary depending on drafts taken and the material being drawn. High nibs are generally used in connection with heavy drafts or where longer bearings are needed. Also, case sizes we recommend are customizable to meet our customers’ needs.
