Marking systems are used widely for the purpose of identification and traceability. They are required in all major industrial sectors like automotive, railway industry, medical industry, plastic industry etc. Within these industries, there is a continuous rise in the requirement for traceability solutions. This traceability comes from markings which have data embedded into them. In an industrial process this data is used for inventory control as well as quality control. The dot peen technology is most commonly used technique for markings. The metal marking machine fall into several categories that include Dot marking, Scribe marking, laser marking, electrochemical marking, manual and press marking and engraved dies. Out of these, dot peen marking systems are popular in industries.

The dot peen marking machine creates a succession of dots to form digits, texts, logos or 2D data matrix codes. The machine works by striking a diamond or carbide stylus assembly, electromechanically against the surface of a part to be marked. The dots created in this fashion are essentially the result of pulsed current that runs through ...
... a solenoid, punches a mark towards the surface and subsequently returns the stylus to its starting position. The machine works at a rapid speed since every pulse takes only a fraction of a second. This results in the entire 2D data matrix code completed in only a few seconds. The evolved technology of dot peen machines allows for a constant and precise control of the impact consistency.

Major characteristics of Dot Peen Making Machine are:

• Highly economical, since no consumables are required.
• Multi-purpose: can be used for all sorts of surfaces
• Direct keyboarding prevents complications
• Utilizes singe source of energy
• High speed accuracy
• Marking of any given material, including hardened steel
• No requirement of compressed air.

Dot peen can be used for permanent marking of any surface material like metals or plastic parts, regardless of surface properties and working environment. So the technology is used widely in marking agricultural machinery, oil & gas industry, metal working industry, electronics components, transportation and logistics industries , construction equipment, etc. The unique component identification is widely required in automotive and aerospace industries. Dot peen technology is therefore used commonly in these industries. The Dot peen markers are available in three main categories, namely, Individual work stations, Integrated systems and portable hand held units.

Individual work stations: These are column- mounted machines. They work as a secondary marking process operating alongside production lines. They are designed to ensure a long shelf life and reliability irrespective of working environment.

Integrated systems: These systems are directly integrated into production lines. Such systems have a compact design, long-term reliability and high marking speeds. There are three different customizable options you can choose from.

Portable hand held units: Suitable for working environments where maneuverability and versatility is required. The E1 series of hand held units are the latest development of portable dot peen markers. They are designed for enhanced portability and maneuverability. The E10 series are upgraded versions of E9 series.

The dot peen technology can be used to permanently mark surfaces up to 63 HRC hardness. In addition, this technology does not cause any kind of stress on the surface that is being marked.
