Ionbond™ 40 a-C:H:W

Versatile PVD DLC coating for use in metal forming and plastic injection molding applications

Ionbond 40 is a DLC coating with excellent toughness, a low coefficient of friction, and good galling resistance. These characteristics make it a coating well suited for forming tools for galvanized, prepainted or aluminized sheet steels. The higher levels of toughness in Ionbond 40, which results in an improved resistance to cracking, compared to other carbon based coatings makes it a preferred coating in forming of nonferrous materials where pressures are high.

The low coefficient of friction of Ionbond 40 allows it to be used in plastic injection molding applications where sliding friction contributes to tool failure. Ejector pins, slide cores, and tools for bottle closures are common examples of where Ionbond 40 is used in plastic injection molding.

Ionbond 40 is deposited between 160° and 250°C. The process allows a wide variety of tool materials to be coated below the respective tempering temperature which ensures that no softening or dimensional changes occur.
