Superficial processes

The semi-automatic system for Inspection with Fluorescent Liquid Penetrants has been designed in such a way as to be able to use both the Washable Penetrant with Water and the Post-Emulsifiable Penetrant with Hydrophilic Emulsifier. In this way, it is possible to carry out inspections in accordance with the various methods envisaged by international standards.

We at A.Abete srl are an Italian company that operates in the precision mechanics sector with dedication and passion. Among our objectives, there are not only the production of components and assemblies for engines and structural parts of aircraft; others are goals to have and want to achieve. Innovation and development are two of them. We persevere in the research and updating of our machinery, in order to always be the exact answer to the needs of our reference market. The shot peening technique can be an example. This technology is one of the most critical surface processes in aerospace engineering. Shot peening, in detail, is a cold process which, by generating residual compressive stresses on the surface of the components (surface hardening), increases their resistance to fatigue. Our system is of the latest generation. Built in 2013, it is equipped with a single nozzle moved by a FANUC anthropomorphic robot and a revolving workpiece table. This makes it a seven-axis machine, capable of shot peening all surfaces, whatever their position, their complexity and their inclination, always guaranteeing an angle of impact of the shot between 45° and 90°, i.e. guaranteeing everywhere the achievement the peening intensity and coverage required.

The two separate galvanic lines, one for the treatment of aluminum alloys, one for the treatment of titanium alloys and steel, make it possible to rationalize and streamline production. In detail, it is possible to carry out the processes of Chromic Anodic Oxidation, Sulfur-Boric Anodic Oxidation, Sulfur-Tartaric Anodic Oxidation, Colored Chemical Conversion, Passivation of titanium, Passivation of steel. The automatic systems, which manage the work cycles via PLC, constantly monitor parameters such as temperature, PH, conductivity and the level of the tanks, guaranteeing full compliance with the customer’s specifications.

The automatic painting plant is divided into three distinct areas: a controlled temperature and humidity booth, a drying area, and a controlled temperature oven. The timed chain, which moves the pieces between the three areas, allows the work cycles to be programmed according to the customer’s specifications, so that the flash-off and paint polymerization times are always respected.
