mobil-mark® marks a variety of materials.

The laser uses a wave length of 1064 nm and can be used in continuous wave (cw) mode, as well as in pulsed mode. Pulse peaks of up to 30 kW allow the use with high thermal applications, for example, steel heat coloration and engraving, and excellent discoloration of plastics. With the direct marking of parts of metal, plastics, rubber, latex, ceramics, wood, glass, as well as plastic films and foils, you achieve a durable, abrasion-proof and forgery-proof result. Depending on the material there are different procedures to be used. Regardless of which of the available processes you choose to use: the laser marking results are quite remarkable.

mobil-mark® marks a variety of materials.

We offer the following procedures for laser engraving:

Application procedure

During this procedure, special laser colors are being fused onto the part with the energy of the laser beam. The application height amounts to only fractions of a millimeter. In this manner lettering in different colors are created, while the surface is left almost unchanged. The application procedure is especially well suited for glass and ceramics.

Frothing and carbonization

During frothing gas bubbles are being created in the surface. A slightly elevated label emerges and a color change sets in. The gas bubbles generate a light, white or grey marking in plastics. During carbonization the conversion from plastics to carbon results in a dark marking.

Ablation procedure

A widely used technique is the lasering off or “shooting off” of color layers. This technique removes the paint from specific spots on a lacquered part, thereby generating markings, such as symbols and logos.

Annealing marking

The annealing marking is especially suitable for stainless steel. Depending on the material very high contrast is achieved and no ablation occurs.

Engraving

The engraving leaves an indentation on the part. The immense pulse energy of several kilowatts, which only lasts billionths of a second, shoots the material and an ablation, like the one resulting from sandblasting, is generated. Throughout, the material itself stays virtually cold, so that even very thin sheet metals can be labeled.

Marking with inert gas

Long-term tests prove it: Engraving in an inert gas atmosphere does not cause stainless steels to rust. Under certain conditions, stainless steel can oxidise under the influence of oxygen. Mobil-Mark’s special inert gas, on the other hand, does not contain oxygen and is introduced as a laser medium during the engraving process. The laser can be supplied with the gas in no time at all via a switchover unit. Finally, it ensures that corrosion processes are prevented, so that nothing stands in the way of long-lasting, high-quality engraving. See for yourself: The workpiece above was sprayed daily with a strongly chlorinated, alkaline foam cleaner in an inert gas atmosphere after the engraving by a well-known customer from the food industry. After a test phase of about two months, the engraving still looked the same as on the first day! Workpieces engraved in an air atmosphere corroded already after the first spray treatment for comparison.
