What we do
A niche industrial craft, mastered in continuous operation
We treat high-purity aluminium foil in a continuous electrochemical process, for use in electrolytic capacitor anodes. The foil is etched, formed and cut to each manufacturer’s specifications.
A specialist in this value chain since 1945, SATMA INDUSTRIES serves a demanding industrial clientele: capacitor manufacturers looking for a reliable, precise supplier able to deliver consistent volumes over time.
Etching
Continuous electrochemical etching of the aluminium foil, developing the microscopic surface area that drives capacitor performance.
Forming
Forming accelerates the electrochemical oxidation of the aluminium foil. This controlled oxidation creates the oxide layer that forms the capacitor’s insulator.
Cutting
Cutting and conditioning into coils at the widths and formats requested by the customer.
Products
