Autophoresi Chemical Coating

ZINCO-CROMATURA srl installed the first Autophoresi ACC® 866 plant in Italy in December 2000 on licence from HST.
With this new technology, patented by HST, you obtain ionic self-separating plating on metal and composite surfaces that are highly elastic and resistant to corrosion.
Autophoresi is a coating that can also be applied on surfaces that are hard to reach with the usual plating systems.
The plating is based on the CHEMICAL REACTION between the reactive bath and the ferrous surfaces immerged in the same that are covered uniformly regardless of their shape.
This treatment has the properties of guaranteeing protection on parts with cavities, protuberances and straight or shaped pipes, in which case the protection is also applied inside the same as well as outside.
Plastic or rubber parts aren't coated so it is possible to treat objects that have already been assembled with these materials, considering that the highest temperatures of the process don't exceed 100/120°C.
Threaded nuts and bolts can be treated normally because Autophoresi doesn't leave deposits on the threads, but respects their conformity.
For the car industry, this treatment has integrated the traditional rust-prevention system and also in this sector, Autophoresi can be used on parts with complex shapes.

The Autophoretic treatment is an ECOLOGICAL process.
The parts treated with the Autophoresi ACC® 866 process are treated without:

  • organic solvents

  • sulphates, chlorides and heavy metals

  • limits of penetration caused by the Faraday cage

  • thermal influence

Parts treated with Autophoresi are at the end of the productive process, ready for packing and therefore it is possible to avoid having semi-finished parts sitting in the warehouse and also simplify bureaucratic procedures and costly warehouse management.
This gives you an idea of the enormous economic advantages that the client has by choosing the Autophoretic coating for their articles.
