Marking coloured aluminium parts
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 giftware 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.
