Technological information

This section contains our technical articles: how ultrasonic cleaning works, dedicated technical solutions developed for our customers, etc.


What is the difference between magnetostrictive, piezoelectric and multifrequency ultrasound?

Its basic principle makes magnetoelastic ultrasound is one of the oldest ultrasound technologies. However, in the past it was very inefficient.

Piezoelectricity was discovered later and this is very cheap and is also imported cheaply from Asia. This explains why many manufacturers turned to piezoelectricity.

Coating is a varnishing process where we apply a layer of varnish to a lens in order to make it more resistant or to give it special properties when it reacts with light...

Dip coating consists of immersing a lens in varnish, which makes it possible to ensure that both sides of the lens have the same properties. As a general rule, applying varnish makes lenses stronger and scratch-resistant.

This sector represents nearly 20% of the group's turnover.
Our method, which combines ultrasounds and the chemical action of a cleaning product, allows us to achieve a high level of performance.

It is this high level of quality that allows us, in the aeronautics industry, to respond to markets for the production of new parts but also in the field of maintenance.

FISALABS conducts research within the group.
Among their latest developments, the Machine Controller Unit (MCU) is a powerful control and management HMI that enables you to program FISA machines.

What is the purpose of the Machine Controller Unit (MCU), and why was it developed ?

The MCU is a machine control and management HMI that has been entirely created by FISA.
