*NEW* Cincinnati now has a source for Industrial Metal Etching/Engraving and Marking.

Surface marking for medical use, deep engraving/etching for weapons, or anodize bleaching.

Why Laser Etching / Laser Marking / Laser Engraving?

    Where other forms of marking can fade or wear away over time, using lasers for etching or marking can last a lifetime. Our laser engraving process provides a permanent fast and effective abrasion-free and contact-free means of marking or etching many different materials and shaped surfaces.  At Liberty Laser, our top-of-the-line laser marking and laser engraving equipment delivers clean edges and fine detail, providing a superior quality laser mark with less waste by directing a laser beam as small as 0.002” in diameter

  Our laser software can import the following format files: .eps; .pdf; .cdr; .bmp; .jpg; .jpeg; .gif; .tiff; .png

  We can laser mark text message, serial numbers, company logo, part numbers, graphics, Bar Code, Data Matrix, and QR Code on all bare (plain), painted, and anodized metal surface finish.

More Materials–More Surfaces

    Whether you are looking to mark or etch metal, plastic, glass, leather, wood, or other surfaces, Liberty Laser is equipped to serve your needs in Cincinnati.  Environmentally friendly and responsible facility.

Environmentally Responsible Alternative to Other Marking Methods

    A Liberty Laser marking provides a permanent, clean alternative to chemical etching, silk screening, stamping, electro-etching, and pad printing.

Laser Marking / Laser Engraving can provide permanent marks on the following materials:

Aluminum  - Anodized Metals  - Plated Metals  - Painted Metals  - Stainless Steel  - Titanium  - Brass  -    Copper  - Ceramic  - Quartz  - Glass  - Black/White ABS  - Carbon Fiber  - Polycarbonate  - White PEEK  -  Polysulfone  - Silicon Wafers  - Colored Delrin  - Magnesium  - Most Crystal  - Most Plastics  - Most Woods  - and more…

Engraving can range from white to dark, with depth or just a surface etch or deep metal ablation, depending on the material and the settings used.  Barcodes, serial numbers, logos and other identifying information can all be engraved.

Laser Marking / Laser Engraving may not be done on the following:

    BeCu (Beryllium Copper) - carcinogenic when airborne
    PVC (Polyvinyl Chloride) - releases chlorine gas

Laser Etching / Ablating / Surface Removal

    Materials:  Anodized, Black Oxide, Painted or Coated Materials
    This type of mark is created by removing the surface coated layer of a material, such as burning the anodized layer off of aluminum.  This usually results in a bright or white colored mark when contrasted with the coating.  The mark is relatively smooth with minimum surface penetration.

Metal Engraving Processes:

Burning / General Marking

    Materials:  Steel, Stainless Steel, Aluminum, Brass, Copper, Titanium, Carbide
    This type of mark is created by aggressively burning the surface of the material.  Depending on the substrate, the mark will vary in color from medium brown to black or black/grey.  The surface of the material will feel rough to the touch and feature areas of rise and fall of material.

Annealing / Black Surface Marking

    Materials:  Steel, Stainless Steel, Titanium
    This type of mark is created by applying a large amount of heat to the surface the material while minimizing the aggressiveness of the mark.  The result is a solid black mark with a smooth surface finish with excellent contrast against the surrounding surface.  This process when properly done, removes little to no material. It is commonly used in the medical field for marking medical/surgical tools, implants and instruments where high contrast is desired and no crevices can be inherent in the surface of the product due to bacteria trapping. This method works best with metals with a carbon content, but is not very desirable if the marking area is very thin due to the amount of heat involved in this method. When marking thin wall areas using the laser annealing method, often times the material will become distorted within the marking zone and thus, parts with more than 1/32” thickness is recommended.

Deep Engraving / Material Removal

    Materials:  Steel, Stainless Steel, Aluminum, Rubber, Various Other Substrates
    This type of mark is created by removing material to create a mark that has depth.  The resulting mark has an embossed look.  The mark depth can vary from minimum to extreme depending on the time allowed for the marking process. Stripping small layers to get desired depth is preferred.

Frosting / White Surface Marking

    Materials:  Carbide, Aluminum, Stainless Steel, Chrome Plated, Nickel Plated, Galvanized
    This type of mark is created by frosting the surface of the material at high speeds.  This usually results in a bright or white colored.  The mark is may have a slight texture to the touch, but the surface or coating penetration is minimal if none at all.

Foaming / Color Change (Plastics)

    Materials:  Various Plastics
    This method is used in plastics where the color of the plastic changes under the laser beam as the material is heated by the beam.  This usually results in white, tan or dark colored mark depending on the plastic.  Some plastics do this naturally and others have additives that are engineered into the plastic compound to achieve high contrasting images when exposed to the laser beam. During this process, specific laser wavelengths are absorbed into the material in order to achieve this color changing effect. Typically no material, or a trivial amount, is removed from the surface. Many consumer electronics and medical devices contain this type of marking. Controlling the heat is very important.
