There are loads of direct part marking methods, however the appropriate method for marking a element is selected by as certain factors. Direct part glom is an important approach of regarding parts. The UID data of the item is directly etched on the surface of the item for permanent UID glom of the item. Generally, the industries like automotive, aerospace and electronic brands ultimate for direct component marking system of their items for reliable peekaboo solution. Assuring warranty, safety also satisfying regulatory solution for their requirements, the administer part marking enhances the item tracking and bridle of loads of jurisdiction and personal assets. Different types of direct part marking methods are Electro-chemical etching, dab peen, forge or mold, Cast, adhesive dispensing, Abrasive blasting, Stencil, Lique metal jet, LaserShot peeing, Laser marking, Engraving/milling, tapestry. However, these methods are selected carefully for each of the marking requirement. preference of Direct Part Marking MethodsThere are various methods of direct part markings. But, all the methods are not applicable to all kinds of parts or items. In fact, the contractors need to select the appropriate method for stare the parts depending on various factors. Functional Aspects of the PartIf the parts are used seeing safety critical applications such as in air-craft engines or high-stress systems, the contractors should prefer to use non-intrusive marking methods. body of the Item or the PartsThe geometry of the part is responsible to decide the method of direct component marking of the item. owing to instance, if the surface of the component is bent it is difficult to carry the UID data making it awful in that control part leer. A tedious surface is always suitable for the method.Texture of the Item SurfaceIt is easy to etch the 2D data matrix code on a rough attend thanks to direct component gander where as difficult for a highly intense surface. In case it becomes vital to tag the part with DPM, the note of the surface is strapped before the strategy is applied. Size of the Part/ItemThe application of the UID and 2D data matrix code are not based on the size of the items. In fact it is the size of the codes that are unshakable by the size of the items. In case the part is too minor the size of the codes are adjusted accordingly and the methods also certain hence that can produce the required result. operating Environment of the influence and their Life SpanAs it is important to have permanent marking solution with the direct component marking, the marking methods are determined according to the working environment. For instance, if the part is more malignant to heat, the efficiency and durability of the marking should be selected accordingly. Also, the functional life-span of the items differs for at variance items, which influences the selection of marking method for the items. Width of ItemsThickness of the items are one of major matters of consideration while direct element marking. Otherwise, adept are chances of deformation of the parts curious their functionality. With most of the gaze methods, the marking intensity doesn’t exceed 1/10 of thickness of the item.
