General Hints for Machining Aluminium Enclosures

General Instructions for Machining Aluminium Enclosures

Please make sure that all residues of any coolants or lubricants used in machining are removed if plastic parts must be attached to aluminium enclosures (e.g. plastic cable glands, adapters, plugs, etc.). Coolants and lubricants can cause plastic parts to become brittle and split. Also, remember that when aluminium castings are machined, enclosed air bubbles, known as shrinkage holes, can be revealed. The casting process and alloys we use result in very few shrinkage holes.

Instructions for Machining Aluminium Plates

For reasons of design and stability, we offer aluminium front panels for many of our plastic enclosures. These panels are cut from anodised plate material, so the surfaces have an anodised layer, but the cut edges do not. Please remember that screen-printing or tampon printing on the anodised layer may not always adhere properly. When machining and imprinting front panels to customer specifications, we use aluminium plate material which, depending on the requirements, is only anodised after imprinting. The advantages are that all the edges are corrosion-proof, and any imprinting will not rub off.
