Electrostatic bars

11/28/2007 10:03 AM

I am looking for information or manufacturers of electrostatic systems to apply sheets of paper to stainless steel coils, in cut-to-lenght lines, after leveling, and before shearing, to reduce scratches during the stacking process of the cut sheets.

Christian,

This must be a tough one. Usually, there are almost instantaneous replies on this forum. Quite a few of them are real knowledgeable experts or at least have some good ideas as to where to go for your information.

I am somewhat interested in this and am looking forward to some answers.

Good luck.

Randy

Hello Christian Bargsted

I was some 20 years ago, Quality Assurance Officer in a factory which did considerable work on sheet metals, including stainless steel sheet punching and forming.

I have never seen paper used as a separator between sheets of stainless steel to reduce scratching.

The main reason is that paper is hygroscopic, thus drawing moisture between the sheets, causing localised marking of the polished stainless steel sheets.

Stainless steel sheet metal is generally covered on one side with an easy-peel-off plastic sheet, which has a temporary adhesive on the back of that flexible plastic sheeting material.

The other reason paper would not be used (in my opinion) is that the stainless steel sheet would discharge the electrostatic charge on the paper, as it touched the metal.

I'll have a sleep on this one, see what else I can locate in the dark recesses of my mind.....
