Dot Peen Technology – Dot peen technology functions by electro-mechanically, diamond shaped pointed stylus which is used for scratching letters through its pointed end. As a result a sequence of dots is formed to create logos, texts, codes and digits. A current runs through the stylus, creating a pulse resulting in action, which means that entire data code can be imprinted in seconds. The dot peen technology is very unique due to its constant measurement of the current which flows in the pulse. The characteristics of this technology are – it gives high accuracy, it is speedy and cost effective, it can print on any material and compressed air is not required during its operation.
