Color Laser Marking Machine

Color Laser Marking Machine used to coloured parts are commonly used from decorative applications in a wide range of consumer goods and marking of these parts is generally achieved though the removal of the coloured anodised layer to reveal the base aluminium material either a white or silvery mark depending on process conditions. Commonly used in gift-ware and consumer goods, alphanumeric and marketing logos are typically marked.

 

The use of lasers for colour marking is not a particularly new technique as it has been recognized for over 10 years. This technique was originally identified as a viable process for use on craft metal work and jewellery. However, the process has had very little commercial impact in the intervening years. There is now a greater interest in this process as manufacturers of consumer goods are looking for new techniques and finishes to provide product differentiation. This application note looks at a variety of materials that are colour mark-able including titanium and stainless steel, and explores the benefits and parameters of the pulsed fiber laser in relation to this application area.

 

Benefits :

  • Significant improvement in the quality of the mark due to the stability and controllable of the laser source.
  • Beam intensity and spot size enable the use of small mark widths.
  • Output power stability over time enables complex mark patterns without power fluctuations – no weld defects.
  • High power density allows large marking areas to be processed rapidly.
  • Maintenance free (no replaceable parts).
  • 3-Dimensional marking can be easily achieved.
  • High repetition rate is achievable.
  • Low frequency (<20 kHz) – control of heat input; processing of thermally sensitive plastic can be controlled (increase in heat might cause the plastic to melt).
  • Low M² – the depth of field is high.

 

Features :

  • Enhanced Optical Tolerances Enable Plug and Play
  • High Reliability/ Stability – Standard 1 year warranty
  • Enhanced Interfaces can be used in combination
  • For Greater Flexibility And Advanced Pulse Control
  • Extended Hardware Control I/O
  • Serial Control via RS-232 and Ethernet
  • First And Last Pulse Equally Usable
  • Bitmap Marking Compatible
  • Status Monitoring And Safe Shut Down High speed marking (MHz repetition rate)
