New project!!
Cleaning process carried out by degreasing, pickling and passivating by immersion, managing to eliminate all impurities with which we receive the pieces, so that they are impeccable when delivering to our client.
The piece (copper) shown below is the way it has been received at our facility. In the main image you can see the part ready to deliver to the customer after processing. 
In the following images, we show you two more pieces in which you can see the change of them, being treated by the cleaning processes that Libein uses. 
The materials to be treated are copper and stainless steel.
