Controlled Roughness

Background

The treatment that contributes to improving the adhesion of a subsequent coating of the component.

PREPARING THE SURFACES
This treatment etches a series of microscopic peaks and valleys on the surface of the piece. The etching, and consequently the roughness obtained, contributes to improving the adhesion of a subsequent coating of the component.
For this reason, the artificial change caused by the blasting of the surface is called “anchoring”. Each coating requires anchoring with specific characteristics. In general, thinner coatings require “soft” anchoring, while for very thick coatings the etchings generated by sandblasting are usually deeper to increase the adhesion. Hence the need to have a specific treatment of “controlled blasting” that makes it possible to achieve and maintain goals over time.

OUR ANSWER
Our machines are designed and built to respond with maximum efficiency to the high quality required to successfully perform this particular controlled sandblasting treatment. The systems dedicated to this specific treatment are equipped with control systems that can continuously monitor the basic parameters for the proper execution of the process, to ensure its constancy and uniformity over time.
