SPECIAL PROFILES

FIAV L. MAZZACCHERA S.p.A. produces profiles with particularly complex geometry and shapes, in all types of steel.
The benefits of the technological solutions set up by FIAV are countless: utmost dimensional accuracy, reduced raw material and labor costs, and less investments in production systems and facilities. FIAV customers may purchase small amounts of profiles, which helps to avoid excessive and undesired stocks.
In some cases, this promotes the development of new prototyping products by the customer through pre-series or mini-series at more affordable costs.

CASE HISTORY

A customer brought 2 technical drawings of a profile that could not be produced since the geometric and metallurgical features were not compatible with available technologies.

FIAV’s technical department team worked closely with the customer, it studied and offered alternative solutions until it found the ideal geometric solution that perfectly balanced component functions and production technologies. The geometric study was followed by a long prototyping and metallurgical research and development phase allowing FIAV to develop the required profile and to start production.

The production of inserts for gasket joints is one of the main application areas for FIAV special cold-drawn profiles.

FIAV, together with the customer, deeply examined the regulations on water transport and relevant safety systems. The profile had to be incorporated in the water transport pipes, ensuring their long-lasting assembly. After examining the geometries requested by the customer and coming to the conclusion that they were not feasible, the technical department worked alongside the customer to find the geometric solution that could guarantee the safety standards required for the correct functioning of the water transport pipes.
