    Labels suitable for 100 Deg C

    Hi, I have a spot for label on this product that has a operating temp around 100C I don't want the label to by itself peel out or deform due to temp. There is no way to open the product in field to replace labels. So I request suggestion on label material or any special stick on labels Thx C1

    Seq of operation

    The blind holes you are seeing on the print are holes ready to take a thread forming screws. Now Iam feeling confident to try the anodizing at the end if the operation. Thanks. Is it right that during the process they immerse the entire extrusion into a chemical tank?

    TVP we are the end user & its OK to have layer inside holes if its as little as rn1957 was talking about. I am actually concerned if the anodizing can leave much thicker deposits like sometimes it happens in powder coating.

    Extrusion of screw holes

    Is there a good reference to design extruded holes for tapping holes for screws. Here is an image of the hole I am referring to. The one that goes right thru the middle of the extrusion. http://www.hercules-online.com/catalog/doors_and_windows/3/aluminum_extruded_profile_136.html Thx C1

    Open in read only mode

I don't intent to make changes while I have it open and at the same time have the file available for others who may want to open in writable mode. In our office we use a spread sheet parts log file and more than 20 guys use it. If I am using it...

    Powder coating quality control

    I think a measuring gadget is very much necessary to tell by how much its off. Say for example RAL 8007 & RAL 8011 appear to be same. But in reality they are different.
