For thegovernment contractors, willing to submit their items to UID registry, theDepartment of Defense has implemented ISO marking standards. The ISO/IEC 15426section 2 of the MIL-STD-130M standard handles the classification of 2-Dimensional bar coding. However, the Department of Defense gives priority tothe levels or plates mode of marking instead of direct part marking. As per theauthorization of DoD, only 20% of the UID markings will be by direct partmarking and the rest 80% will be on nameplates or levels. For bar coding, thetraditional nameplates are made up of several metals such as stainless steel,brass and aluminum. Anodized aluminum blank nameplate is considered standardform as it offers better durability. These long-lasting aluminum nameplates areused for bar coding for their sunlight and heat resistance quality and betterabrasiveness.
In fact,the durability of the anodized aluminum nameplate material is due to itsflexibility and thinness. Apart from being quite strong, the metal islightweight and they posses the quality to easily bend around the products. Againthe aluminum nameplates are anodized to make it resistant to excess heat, abrasionand chemicals. The anodized aluminum blank nameplates are also ideal foraerospace industries, commercial and industrial use as they can survive harshclimatic conditions and extended exposure to UV rays with little damage. Apartfrom the basic metal colors, the nameplates can be coated with several othervibrant metallic colors such as gold, purple, copper and dark blue, but thecolor is chosen once the nameplates are anodized.
Theanodized aluminum blank nameplate can resist temperature up to 900'F-1200'F asthey are made of durable anodized aluminum. Apart from this, the anodic layerof the aluminum protects the item info as well as the logo from chemicalabrasion and high temperature. Also the nameplate offers the clarity of theproduct code info and the logo. The aluminum nameplates are widely used for thelow tooling costs of decorating and serialized numbering on them. The adhesivesare generally not recommended for the nameplates as they are required to resisthigh temperature. Rather the anodized aluminum blank nameplates ought to beused with holes or mechanical fasteners.
Often, theanodized aluminum blank nameplates are personalized as per the requisite of themanufacturers. Of late, a new form of anodized metal nameplate, also known as photoanodized metal nameplates, has been widely in use. These superior qualitynameplates possess the features to resist extreme environmental conditions,increased heat (more than 1000F), and more harmful UV rays. These nameplatesare also coated with anodic layers of aluminum that makes them as durable andsafe as the anodized aluminum blank nameplates. Along with the basic mechanicalfasteners, the new kinds of photo anodized nameplates come withpressure-sensitive adhesive.
Asthe photo anodized metal nameplates can reproduce logos, black copy andbarcodes photographically, they are more useful than the anodized aluminum blank nameplate. They ensure reliable and accuratereads. Apart from the specially matched adhesives they have optionalintensification process to resist increased heat and advanced image resistancefor different environmental conditions.
