Marking and coding rules are not only valid for gold bars, but also for silver, palladium, and/or platinum. This can cause possible weight loss of the ingot. However, it is important to know that marking with lasers can be problematic with ingots due to the consequential evaporative-stress the material undergoes during its’ marking. Laser machines are software-driven and thus guarantee maximum flexibility in the marking process. This is the least used solution, but, thanks to new technologies and new types of lasers, it is considered a valid solution on some processes. This technology can only be used on ingots with perfectly flat surfaces. Scribe marking consists of a tip that “scratches” on the surface of the material being marked, thus producing a continuous line. Thanks to its’ pneumatic and electric characteristic, the dot peen machine is useful and adaptable to different types of markings: deep, continuous or “light/superficial”. This technology allows to mark ingots with maximum flexibility because of its software-driven and progressive electronic nature. #Johnson Matthey Gold Serial Number Lookup manualWith both manual or pneumatic operation, it is normally used with numbering heads for serialization of the ingot (as shown in the example photos). Is the least expensive and, at the same time, a fast and deep marking solution. Hence, the only marking technologies allowed are those which fully respect these characteristics.Īmong the various marking technologies, the most suitable are the following: The marking techniques imperially cannot alter or modify the shape, size and above all, weight of the ingot. Industrial marking, or commonly called stamping operation, is not easy. According to the rules imposed by London Bullion Market – the London market for gold and silver ( LBMA) each ingot must have certain specific information-tied markings, such as: This is done for security, coding and traceability reasons. By law, each gold bar, no matter the size or shape, must be mandatorily marked and serialized before being placed on the market.
