Environmental Responsibility

The Stelmi process easily meets the most severe environmental control requirements. The conventional plating processes used by our competitors require massive, complex and expensive control equipment and offer limited security.

Water and air discharges

Stelmi's chromium baths are closed loop relative to wastewater which eliminates the need for special discharge permits. The plating machines work slightly under the atmospheric pressure and vent directly to our air control systems.

Solid wastes

The only wastes resulting from the process is the mud generated from the physical and chemical treatment of the water. Its volume is reduced to about 5% of those generated treating the waters of an equivalent conventional plating plant.

Chromium bath volume

Stelmi's continuous chromium plating technology uses no "pits" or below grade tanks. The process requires a bath volume which is one tenth of what is required for conventional plating equipment offering the same production capacity.

Chrome overlay

Continuous and automatic monitoring of the characteristics of the chromium bath, coupled with the smaller scale of the bath, guarantees a chromium layer that is completely homogeneous.

Less power installed

The Stelmi process helps to save energy. Due to the smaller plating baths and the use of anodes that conform to the shape of the bar, the Stelmi process demands one third less electrical power than conventional plating.
