Pulsed-Plasma Diffusion: the future-oriented surface treatment
Pulsed-Plasma Diffusion: the future-oriented surface treatment

Hard chrome-plating was the automotive industry's method of choice for wear protection treatment of large moulds. Oerlikon Balzers’ BALITHERM® PPD (Pulsed-Plasma Diffusion) sets a new industry standard for efficient and environmentally-friendly wear protection. PPD® technology uses no hazardous gases or chemicals - just hydrogen, nitrogen and electricity.

Whereas up to ten cycles of hard chrome plating are required, for example, during the lifetime of car body parts tools (each time using harmful chemicals), with BALITHERM® PPD they need only be treated once!

The industry’s largest tools can be accommodated by the INAURA system with its 33 x 10 feet (10 x 3 meter) chamber and 40 metric ton load capacity. A fully automated process ensures consistent and controlled wear protection treatment.
