Application of High power UV laser source marking on plastic

If the two scanning galvanometers are mounted at a 90-degree angle to each other, then a UV laser marking machine can mark both sides of the workpiece. The transition time of the laser beam moving from one scanning galvo to the other is about 50ms.

UV laser marking machine: discoloration

Marking on plastic electrical switches generally changes the color under the surface of the material, such as carbonization. When using a UV laser marking machine, black marking can be achieved by selectively carbonizing the subsurface of the plastic. The input of heat energy is limited to a small designated area, so that the marking content and the background material are clearly distinguishable and easy to identify.

The wavelength of the UV laser marking machine is 355nm. It provides a new method for marking plastic electrical switches. In addition to the characteristics of general marking machines, the additional outstanding advantage of successful laser is: one laser head can be installed with two scanning galvanometers. So the marking speed can be doubled, or the part can be marked on both sides. The fastest marking speed can reach 3000 characters/sec.

The application of UV laser marking machine has attracted much attention because it has created a new way of marking plastic materials. The energy output by the short-wavelength ultraviolet laser stimulates the photochemical reaction of the material, and the ultraviolet laser marking machine avoids the excessive input of heat and causes the material to be damaged. The main features of UV laser marking machine: fast speed and high resolution. When processing some sensitive materials, such as plastics containing flame retardants, UV laser marking machines can achieve high-resolution marking with the best surface quality and fastest processing speed. Compared with infrared and green laser marking machines, UV laser marking machines do not require any expensive laser-sensitive additives during material processing, which can significantly achieve faster processing speeds and better marking quality.

Mark the same content at the same time

Success Laser's UV laser marking machine for plastic applications Dual scan head system with synchronised beam splitter, each scan head outputs 1/2 of the laser energy. The two scan heads simultaneously print the same content on the workpiece, doubling the throughput of the entire system.

Mark the same or different content in sequence

Dual scan head system with asynchronous beam splitter, different content can be marked separately in sequence. The energy of the laser is not split, and all the energy of the laser is introduced into the two scanning galvanometers in sequence by the shutter. The marked content can be the same or different.
