Which product to use?
Choosing the correct TherMark product for your marking needs depends on what your priorities and requirements are for both your mark and marking process. For some, the blackness of the mark is the determining factor, while for others a required production quota makes marking speed the most important consideration. In other situations, delivery method is a key factor: in some applications a liquid ink is not appropriate and a dry application method like a tape is preferred. Finally, some substrates are more challenging than others and require specialty products. The chart below gives some product recommendations based on a number of different considerations. We recognize that a combination of these factors will likely contribute to determination of the best product for your needs, so feel free to contact us for a consultation.
Black on Metal
TherMark’s LMM series laser marking materials are specifically engineered to create high quality black marks on a wide variety of metals. The contrast, resolution, and durability of these marks make TherMark materials ideal for Bar coding, 2D data matrices, product serialization, direct part marking, text labeling, part traceability, branding, and logos and decorative marking.
There is an appropriately formulated TherMark laser marking material for almost every metal surface. The process window for creating high quality marks may vary depending on substrate composition and/or thickness, application method, and laser type. It is important to note that TherMark materials will not mark over or through clear coat. If you wish to mark a metal with a coating or lacquer, this layer must be removed prior to application of TherMark material. In some cases dual pass operation may be a good solution to this problem, where the coating is ablated during the first pass of laser marking after which the TherMark material is applied for final marking. Metals that can be mark include stainless steel, brass, pewter, copper, chrome plating, galvanized steel, silver, nickel plating, aluminum, gold, anodized aluminum and titanium.
Due to the vast number of different metal alloys, the above list is not exhaustive.
Logos and decorative marking
TherMark materials offer clear advantages over every other type of marking in use today. For more information on how TherMark compares to direct laser marking, pad/screen printing, engraving, chemical etching, dot peen, and labeling, please click here.
