DYNA-BLUE PLUS™
Give Your Tooling a Second Life.
And a Longer One.
When standard nitriding or PVD coatings wear out too quickly, DYNA-BLUE PLUS™ is your answer with a deeper, more resilient surface treatment that enhances finish, combats wear soldering, and resists fatigue—proven to last 2–10x longer in even the harshest die casting environments.
What Is DYNA-BLUE PLUS™?
Enhanced surface finish for better release and material flow with longer tool life, even on used tools.
DYNA-BLUE PLUS™ is a powerful surface treatment that combines low-temperature Ferritic Nitrocarburizing (950–1050°F) with a proprietary surface enhancement designed to boost durability, improve material flow, and tool life to used tools.
This dual-action process forms a 75+ HRC compound layer and a nitrogen-rich diffusion zone deep into the steel—creating a wear-resistant surface with increased life, resists soldering and erosion, and enhances part release.
It’s particularly effective in aluminum magnesium die casting and forging tools—where soldering, erosion, and heat checking are everyday battles.
How It Works
DYNA-BLUE PLUS™ improves wear resistance, surface finish, and resists soldering and erosion even with high-silicon aluminum alloys. It can be reapplied and is ideal for reconditioning used tools.
