Compatible Materials: Laser
|Material||Color of Marking||Compatible for Engraving|
|Anodized Aluminum||White, Black||Yes|
|Hardcoat Anodized Aluminum||White||Yes|
|Electropolished Stainless Steel||Black||Yes|
|Painted Metals||White, Gray||Yes|
|Annealing||Dark surface marking. Used primarily on uncoated steel and aluminum.|
|Etching||Very light engraving - small removal of material|
|Engraving||Removal of material to depth. Used primarily for steel and aluminum. Limited use for plastics.|
|Ablation||Removal of coatings like anodize|
|Color change||Used mostly on plastics to produce a contrasting mark|
|Foaming||Used on plastics to create a raised surface marking|
|Bleaching||Used only on Hardcoat anodize (primarily black). Creates a white marking by altering the dye. Does not remove anodize.|
|Masking||Used to remove anodize in specific areas for grounding purposes.|
A marking technique that does not penetrate below the material surface. This technique is ideal for industrial part marking and metal part marking, on delicate materials.
The difference between the laser marking technique and engraving or etching is that marking does not penetrate below the material surface, which is ideal for applications involving thin or delicate materials. Engraving penetrates more deeply into the substrate.
Yes, most plastics can be laser marked. If the properties of the plastics dictate that they cannot be laser marked, the plastic can be modified via chemical additives to ensure it is laser markable.
Yes, laser marking can be done on irregularly shaped surfaces to apply barcodes, QR codes, logos, and other identifying marks.
Laser marking systems generate less heat than other laser part marking processes. Though this method does not penetrate the surface materials and other processes are better for permanent marking.
