Part Marking & Decoration

The process of Part Marking & Etching is a broad category. Some techniques are permanent, whilst others are temporary and wear off over time. The general purpose of Marking is to give a components traceability and to provide information to the user.

The type of Part Marking depends on factors such as material type, part function, part geometry, surface finish, part size and coating thicknesses.

When part function is being considered, these general rules should be followed:

• Laser, dot Peen and Chemical Etch provide a permanent mark.

• Laser and Dot Peen can produce engraved marks for wear resistance.

• Non-Contact Marking is preferred if the part is small or mechanically delicate.

• Non-Intrusive Marking methods are recommended for parts used in safety-critical applications like aircraft engines or high pressure and high stress systems.

As mentioned above the main processes are:

• Laser Marking & Etching

• Plasma Marking & Etching

• Chemical Etch Part Marking

• Engraving & Scribe Marking

• Dot Peen Marking

• Abrasive Etching & Marking

• Printing
