Logos, model names, and lot no's are marked on drills, taps, and reamers used for machine tools.
Conventional Method & Associated Problems
In the past, the client used etching, however markings sometimes became illegible over time. This caused problems because some users could not correctly identify the model name and made orders for the wrong replacement tools.
Advantages of laser markers
The MD-H uses thermal laser marking to give semi-permanent inscriptions that do not deteriorate.
Semi-permanent characters can even be marked on curved surfaces.

Logos and lot no's are marked on high-grade scissors on the production line.
Conventional Method & Associated Problems
The client previously used electrolytic corrosion marking. However, this made it difficult to improve productivity because the process was completed manually. When stamping was used, the stress applied to the products after hardening increased the defective ratio.
Advantages of Laser Markers
The MD-H can automate the marking process and significantly improve production efficiency. The non-contact laser marking method used by the MD-H does not apply stress to targets. The client was able to eliminate defective products created through marking.
A laser marker applies no stress to targets which require hardening.

In the past, the client used an inkjet printer, but sometimes the surface of the cans are oily which prevents the ink from adhering, and causes the print to fade. The client also felt that the black characters were too conspicuous and requested a more inconspicuous printing method.
Advantages of Laser Markers
The MD-H uses thermal laser marking, ensuring clear marking even if the material surface is oily. The laser even engraves the mark into metals, ensuring that characters will not fade. The power of the laser can be freely adjusted to change how the target is marked, enabling less conspicuous marking.
Marking is unaffected by oil on the target surface.

Logos and management no's are marked on bobbin cases used for industrial sewing machines.
Conventional Method & Associated Problems
The client previously used a stamper. As the demand for industrial sewing machines increases in overseas countries (in this case, Asia), more imitations have been appearing. The client felt it was necessary to make its original products identifiable after export and to improve its production history management methods.
Advantages of Laser Markers
The MD-H allows laser power adjustment to inconspicuously mark permanent characters. This is effective in preventing imitations.
Laser marking ensures imitations can be reliably differentiated.
