Metal meets organic: The new Gardo® Hybrid technology for phosphate-free cold forming operations
The Gardo Hybrid technology is the first ever cold forming process for steel without phosphates, based on a conversion coating. With this innovative technology Chemetall, the global leading surface
treatment company, responds to the market requirement for an environmentally-sound cold forming technology, combined with a high forming performance.
The Gardo Hybrid technology replaces the zinc-phosphate layer by a phosphate-free metal-organic one. This innovative conversion layer provides the same excellent properties and behaviors like a traditional zinc-phosphate. However it fulfills more stringent safety and environmental requirements: the product does not contain any heavy metals and the formation of the metal-organic layer consumes less energy.
Gardo Hybrid can be easily integrated into current cold forming operations since no major modifications to the lubricant, treatment line or application process is needed. The reason for this is that the tribological system was not changed; it is still divided into two parts: the conversion layer providing the unique surface and the lubricant on top
Gardo® Hybrid advantages at a glance:
- Less energy due to lower treatment temperature
- Less consumption
- Reduced sludge formation
- No activation needed
- Free of heavy metals, except iron
- No major change in treatment lines required
- No additional equipment needed
- Safety, health and environmentally-friendly
