The improvement of the mechanical properties, especially the fatigue strength, that we were able to achieve by increasing the residual superficial stress, is the most remarkable effect that characterises our process and on which our Company continues its research activities.
The technique requires a significant knowledge and control of the process, because there are many variables to consider.
A second important treatment is polishing. This does not influence the mechanical properties but reduces the level of roughness to very low values (even Ra < 0.1), so as to facilitate any pneumatic and/or hydraulic sealing requirements.
Vito Rimoldi has always been particularly sensitive to environmental issues. For this reason, as the tumbling process requires the use of a significant amount of water, we designed a closed-loop line that reduces the use of water to the bare minimum.
Moreover, it does not require the use of chemical components that are difficult to treat and manage, helping to ensure a low environmental impact.
Our added value
What we can offer can be summarised in four main points:
- In-depth knowledge of the production process
