Marking machines are used for marking purposes on metal items to imprint logo, bar code, high speed character, production labels, signing of vehicle parts, emboss marking or graphics. These machines are used to carve symbols, data or text on the items for permanent identification.

Marking machines can be used for –
• Road markings
• Metal marking on rings
• Marking on name plates or number plates
• Marking on uneven surface
• Cylindrical markings on pipes
• Markings on hard plastic items and hexagonal parts
• Code marking and reading
• Circular markings on flat and narrow items
• Cylindrical marking without rotation of the item and embossing
• Automated markings on machinery on different heights

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.
