ALIT Technologies launches Drizzling, a new dosing and application system for the passivation of metal parts

ALIT Technologies is pleased to announce Drizzling, an innovative process for the application of chrome-free passivation products for all metals.

ALIT Technologies, a leading manufacturer of machines and products for the surface treatment of metals, is pleased to announce the launch of the dosing and application system Drizzling.

The treatment of metal surfaces ensures good durability over time and provides protection against oxidation and corrosion. There are various surface treatment processes aimed at this purpose. One of the most significant and widespread is certainly coating, which is only the last (but not least) step of a chemical process that includes several intermediate stages in which parts are degreased, pickled and passivated. It is in this last phase that the Drizzling system can make a difference.

Overview of the dosing and application system Drizzling

Drizzling consists of a complete dosing system capable of automatically managing the mixing of demineralized water, coming from a feed tank, with the exact quantity of passivating chemical product, thus obtaining an optimal and always fresh solution to be dispensed directly on the surface of metals. The use of special atomizing nozzles and compressed air enables the system to homogeneously produce and distribute a fine and light mist of passivating solution that completely envelops the product, even in 7-meter vertical lines for aluminium profiles.

This system is extremely compact and easy to install, and its main advantage is that it allows to apply a constantly fresh and contamination-free passivating solution to the products: a further reassurance for the customer, who can count on an improved performance of the passivating product.

Furthermore, the new dosing system developed by ALIT Technologies can be combined with chrome-free chemicals, including titanium and polymer-based ALFICOAT 748/3 from Alufinish GmbH, which guarantees excellent results in the passivation process both in terms of corrosion protection and paint adhesion.

The ALIT Technologies team previewed Drizzling at Aluminium, the leading trade show for the aluminium industry and its main fields of application, which took place from 27th to 29th September 2022 in Düsseldorf, Germany.
