Hello all, I am tasked with helping with the start up an aluminum tube bending department at an extrusion shop. I am mandrel bending and using a lubricant on the inside of tubes. Afterwards they must be cleaned with a detergent and rinsed to remove lubrication before going through heat treatment process. My expertise lies in years of tube bending and not with cleaning. My problem is how do I stop the aluminum from oxidizing and losing it's luster during this operation? Any an all suggestions will be greatly appreciated. Thanks in advance.
