The expertise

The continuous electrochemical treatment of aluminium foil is a niche process: we master it end to end, in our own plant.

Process

One continuous production line

The SATMA process, step by step
  1. Etching

    Continuous electrochemical etching: the foil surface is textured at microscopic scale to multiply its effective surface area.

  2. Forming

    Forming accelerates the electrochemical oxidation of the aluminium foil. This controlled oxidation creates the oxide layer that forms the capacitor’s insulator.

  3. Cutting

    Cutting to the specified widths, final inspection, conditioning into coils and packing ready for shipment.

Quality

Inspection at every key step

Product quality is our first concern. Inspection takes place at every key step of the process, from incoming material control to final control before shipment.

The laboratory works hand in hand with the production team: checking methods integrate each customer’s specific requirements, for continuous quality monitoring aimed at the customer’s final satisfaction.

R&D

An in-house laboratory, focused on tomorrow’s foil

R&D is an integral part of the company: refining the oxide layer, tuning the foil thickness, adapting to evolving customer specifications. Successful developments are integrated into the production lines.

Our work also covers the recovery of by-products from the aluminium surface treatment, used in particular as flocculants for water treatment.

Quality and energy management

ISO 9001:2015

Quality management

This certification frames our quality management system and the control of our processes. It is part of a continuous improvement approach and lasting customer satisfaction.

ISO 50001:2018

Energy management

This certification structures our energy management approach and the monitoring of our energy consumption. It supports our continuous improvement actions on the energy performance of our industrial site.

Operations

A demanding industrial site, running continuously

Our activity is energy-intensive and relies on chemical products under strict control. People safety and environmental impact management condition the daily operation of the site, whose transformer station was renewed in 2015.
